Three products in one, and one record underneath them.

Each layer is normally bought separately, with a spreadsheet in between. In FlowSense they share one database, one set of units and one timeline. The figure in the board paper is the reading in the chamber, and you can trace one to the other in your browser.

Monitor

Live fleet status, site detail, alarms, telemetry and battery health, rainfall context, and early warning of blockages weeks before a pipe surcharges.

Monitor

Every site, every minute. Worst first.

The Overview opens with the sites that need attention, listed beside a map that shows where they are. Point at a row and its site is ringed on the map. Filter the map by what is wrong, then click through to the site.

  • Six figures across the topFive open their own list. Alarms to acknowledge are kept apart from any still breaching.
  • Since you last lookedOne line on what changed since your last visit: alarms raised, blockage warnings, sites gone quiet.
  • Needs attention, worst firstOne row per site with its reason: alarms newest first, then recent failures, then the backlog.
  • Where it isEvery site on aerial imagery, ringed amber while an alarm waits and red while one is breaching. Rain radar is one click away.
The FlowSense network map on aerial imagery, with the Layers panel narrowing it to alarms, telemetry, battery and hydraulic risk.

Every site, judged against its own usual.

FlowSense compares each site’s latest hour with its usual pattern for that day and time, learnt from its own record. It says plainly when a site is running above or below.

  • Small departures stay quietA move under 10% isn’t called out, so the list isn’t a wall of amber.
  • No reading, no verdictA site whose newest reading is more than a day old gets no verdict, not a guess.
  • Weather is not a faultRain in the last day is shown beside the verdict, so a rise after rain is never read as a problem.
  • Every channel, not only flowThe list shows whatever a site measures: pH, conductivity, rain, gas, pump runs, power.
The FlowSense Flow Analytics page: a card for every site with its 24-hour trend, latest readings and status.

Whatever the site measures, in the form that suits it.

A gravity sewer, a pump station, a trade waste discharge and an overflow chamber each get one page, laid out for what that site measures. Every chart zooms, pans and exports, and the link you send a colleague opens the same view.

  • A tile for each measurementSet against this time yesterday, with the daily volume, the hours it is based on, and the logger.
  • Pumps read as statesA pump shows how long and how often it ran, never an average.
  • Any window on one time axisEach measurement has its own pane, with pump runs and alarms drawn as lanes on the same axis.
  • Honest about gapsEvery trace breaks where the logger went quiet, rather than drawing across the gap.
A FlowSense site page: the verdict against usual beside the site’s name, then tiles for flow, depth, velocity and temperature.

The failing logger, named before it goes quiet.

A monitoring program fails quietly. A battery flattens, a modem stops answering, and the quarter’s report is already wrong. FlowSense watches the fleet itself, and puts what needs attention first.

  • A replace-by date for every batteryProjected from the site’s own discharge trend and battery chemistry. A dying logger becomes a planned visit.
  • Late, judged site by siteOffline means a site missed its own delivery deadline, so a twice-daily logger is never reported late at hour three.
  • Alarms that reach a personThreshold, no data and pump condition rules send email and SMS once, when the state changes. They go to people, not to addresses.
  • Monday, in the inboxEach reader gets a summary of their own network, waiting at the start of the week.
FlowSense Fleet Health: every logger on the account with its battery, delivery record and a replace-by date.
The FlowSense alarm queue: every rule that has tripped, unanswered first, with cleared alarms kept apart from those still breaching.

Blockages found in dry weather, weeks before they overflow.

A sewer drains almost empty overnight, and an obstruction shows in that trough long before anyone rings the council. Blockage Watch reads it twice a day, sets rain aside, and runs on every gravity sewer you monitor without being asked.

  • A decision, rankedWhat needs a decision first, with its case number, then the sites behaving normally.
  • The call that saves a crewThe level is up because more water is arriving: increased load, not an obstruction. No jetting.
  • The numbers behind itOvernight level and its trend, the headroom left in the pipe, evidence strength and dry days judged.
  • Tested on your own historyA one-click backtest replays the detector against the overflows already in your register. The hit rate you see is yours.

Pump Station Manager

Station flow from the pumps you already run. No flow meter.

A wet well fills as sewage arrives and empties as the pumps move it. So its level, the pump run states and its size make a flow record. EDS has built PSM on that idea since 1991. Today it’s one of the most used tools in FlowSense.

The FlowSense Pump Station Manager: the station’s figures across the top, the wet well drawn to scale with its set-points, a briefing in words, and each pump’s delivery against its rating on a dial.
  1. 1
    The station’s figures first

    What arrived, what was pumped out, and the balance of the two over whole pump cycles.

  2. 2
    The wet well, in kilolitres

    An engineer’s section of the well, with its start and stop levels and the volume each cycle moves.

  3. 3
    A briefing, in words

    What is worth watching and what is for the record, each with a button to its evidence.

  4. 4
    Pump condition, with a date

    Each pump against its rating, a warning when its output slips, and remaining useful life as a range.

Two slopes and a well volume are enough. One slope gives the inflow, the other gives what each pump is actually delivering today. Five hours of wet well level, one station: a schematic, not measured data.
  • Station flow without a flow meterInflow from the wet well level, plus volume pumped, starts and run hours, with the well itself in kilolitres. No chamber work, no meter to buy, no confined space entry.
  • Pump delivery measured, not ratedEach pump’s delivery is the median of its measured days, set against its nameplate or its own first month. Pumps sharing a rising main are never judged against their ratings added up, since together they deliver less.
  • Pump condition, with the time each pump has leftOn dry days each pump is compared with its own reference. A slow decline, a sudden drop or a stopped pump raises a finding and an alarm. Remaining useful life is given as a range, to ISO 13381-1.

It needs very little: the wet well level signal, pump run states as numbers, and the well dimensions. Most stations already produce the first two, so this is usually the cheapest flow data an authority can add.

Analyse

Infiltration and inflow, in kilolitres.

“This catchment is wet” is not a business case. A volume, a peak, a lag and a percentage over dry weather flow is. FlowSense separates the storm from the sewage beneath it and reports what the difference is worth, per catchment and per storm.

  • A baseline that movesDry weather flow from dry days only, split by day type, so a weekend or wet winter is never blamed on the storm.
  • The three-way splitSanitary flow, groundwater infiltration and rainfall-derived inflow add up exactly to the metered total.
  • Catchment closureUpstream against downstream, aligned on travel time, so you know how much of the flow is accounted for.
  • A price on the waterVolumes priced at your own treatment and pumping rates, carried into the capital plan unchanged.

Check the instrument before you trust the number.

Every figure in FlowSense rests on the record being sound. So it scores the record first, names the weak channel, and shows its working when it repairs anything.

  • Depth against velocityEvery depth and velocity pair over the window, coloured by flow. Silt, surcharge, backwater and a failing meter each leave a different shape.
  • Three scores, named for what they scoreOperator health, telemetry and anomalies, with each channel’s completeness and gaps listed, not averaged away.
  • The full QARTOD test batteryGross range, climatology, spikes, rate of change, flatlines and cross-channel residuals, each with a recommended repair.
  • Repairs never overwrite a readingFilled gaps live only in the analysis and the export. The reading the instrument produced is always there to go back to.

Engineer

Severity painted onto the real network.

FlowSense traces infiltration and inflow along the gravity network, by catchment and flow direction, with a confidence for each estimate. The result: a ranked list of pipes worth sending a camera down.

  • Six methodsYou choose the method, and the platform says where your data can’t support it.
  • Along the pipesSeverity follows the way the sewer drains, not a circle drawn round a meter.
  • Confidence, 0 to 1Pipes far from a gauge fade, rather than pretend to a number.
  • Your GIS, as suppliedThe council’s sewer layer loads from the file it came in, and the map exports as an A4 report.
The FlowSense I/I heat map: severity painted along the sewer network over aerial imagery, with the inspection priority list of the pipes most likely to be sources.

A calibrated model you keep, not a report you file.

FlowSense runs calibration, validation and a dynamic wave network model as a project your engineers keep. When the question comes back next year, you run it again instead of commissioning it again.

  • Every storm scored on its ownSimulated peak within 15% below to 25% above observed, and event volume within 10% below to 20% above, to the CIWEM Code of Practice.
  • Honest about its own ceilingMeasured inflow carries noise from the baseline, so the workspace shows the best possible score beside the one achieved.
  • Dynamic wave hydraulicsPipes, pumps, gates and control rules, run from the network’s own dry weather state and exported to EPA SWMM 5.
  • The capital planOptions ranked by net present value, benefit-cost ratio and cost per kilolitre removed.

Commissioned with you. We set up every connection with your IT or SCADA people, using documents written for them. A connection isn’t done until a reading has arrived and been checked.

Eight things you won’t find together elsewhere in Australia.

No other platform sold in Australia carries a reading the whole way, from the chamber to the capital plan, on one record and in one subscription. Each of these answers a question an authority is asked every year.

  • One record, end to end

    The reading in the chamber and the figure in the board paper are the same number, never retyped.

  • Blockages read from the pipe

    Eight dry weather signatures that name the mechanism and the action, backtested on your own overflows.

  • Flow from every pump station

    Station inflow and pump condition from the level and run signals you already have.

  • Infiltration that adds up

    Sanitary, groundwater and rainfall-derived flow, summing exactly to the metered total.

  • Models you keep

    Storm-by-storm calibration, a dynamic wave network and a costed plan, in one workspace.

  • Data both ways

    Five ways in from your SCADA, and the validated record back out.

  • Every number shows its working

    “How this is calculated” on the figures that matter, naming the method and the standard.

  • Priced by the site

    Everything included, unlimited users, and no editions to choose between.

Built to the published standards, and tested against them.

Each calculation in FlowSense cites the standard it follows, where your reviewer can read it. The list comes from the running software, so a standard nothing uses can’t appear on it. Tests against the code check it on every release.

  • CIWEM UDG Code of Practice (2017)

    Storm-by-storm calibration acceptance bands, and dry weather flow as a daily pattern for each type of day.

  • WEF MOP FD-6 and WPCF MOP No. 36

    Dry weather flow as sanitary flow plus groundwater infiltration, from qualifying dry days only.

  • WSA 02 Sewerage Code of Australia

    Self-cleansing velocity, level of service checks, and Colebrook-White friction for each pipe.

  • AR&R 2019 and AS/NZS 3500.3

    Areal reduction factors, design rainfall temporal patterns, and the Rational Method for ungauged subcatchments.

  • QARTOD

    The quality control tests and flag vocabulary used to score each record before it is trusted.

  • EPA SWMM

    Dynamic wave routing, and the three-component RTK method for rainfall-derived infiltration and inflow.

  • ISO 13381-1

    A pump’s remaining useful life, counted down to a stated limit and given with its uncertainty.

  • NSW Liquid Trade Waste Guidelines (2021)

The instruments EDS supplies carry their own certification. The Detectronic LIDoTT range is MCERTS certified for flow metering and rated ATEX and IECEx Zone 0 for hazardous atmospheres. A certified meter keeps its certification when its readings reach FlowSense, which stores the field time and the raw value.

FlowSense is built to these standards and tested against them on every release. EDS does not describe the software as certified, accredited or endorsed by the bodies that publish them.

Since 1991, EDS has measured water and wastewater for

  • Bureau of Meteorology
  • Yarra Valley Water
  • Sydney Water
  • Hunter Water
  • Urban Utilities
  • Aurecon
  • Stantec

What councils and utilities ask us.

If your question isn’t here, our team will answer it on 1300 721 683.

Who owns the data?

You do. Export it in open formats at no charge, and if you cancel at renewal, all of it goes with you.

Do we need to install anything?

No. FlowSense runs in the browser on desktop, tablet and phone. Connecting your SCADA needs no agent, connector or gateway on your systems, and FlowSense has no control path into them.

Does it only work with EDS instruments?

No. FlowSense is vendor independent. It can collect from your own loggers, or take data from your SCADA by HTTPS, MQTT, API, SFTP or FTPS.

Where is the data hosted, and how is it secured?

In Australia, in DigitalOcean’s Sydney region. Sign-in supports two-factor codes, and you set each person’s access down to individual sites and channels. An audit trail records every sign-in, view, change and export.

Can the data go back into our SCADA or historian?

Yes. By scheduled CSV files over SFTP or FTPS, MQTT messages to your broker, or a read API. Signed webhooks fire when an alarm is raised or cleared, a forecast puts a site at risk, or Blockage Watch flags a blockage.

How many people can use it?

Unlimited users, with role-based access, and admin you can hand to your own team.

What does Blockage Watch not do?

It’s a statistical early warning from each sensor’s own history. It says the pipe reaching that sensor is behaving differently, for a reason rain doesn’t explain. It doesn’t locate the obstruction, and can’t see one downstream of the meter.

How do we get started?
