Auditing & Calibration

Audits and calibration of your monitoring equipment where it’s installed, by experienced EDS technicians, so your data holds up.

At a glance

  • Open and closed channelFlow meters, level sensors and loggers
  • AnalyticalpH, EC, turbidity and nutrient analysers
  • On siteAudited and calibrated where it’s installed
  • A record of findingsAdjustments and recommendations documented

A drifting instrument costs you twice: once in readings you can’t trust, and again in the decisions made on them. Our technicians audit and calibrate equipment where it’s installed: closed channel, open channel, level, pressure, rainfall and analytical.

We’ve worked with most of the monitoring technologies available, so we know how each one drifts and how to put it right.

Calibration keeps a long record trustworthy. We’ve calibrated long-term sewer flow gauges across multiple Yarra Valley Water sites, keeping the data reliable for modelling and planning.

What we audit and calibrate

Open channel flowArea velocity flow meters, level sensors and loggers in sewers, drains and channels.
Closed channel flowMagnetic, ultrasonic and other full pipe meters.
Level, pressure and rainfallLevel sensors, pressure transmitters and rain gauges, and the loggers that record them.
AnalyticalpH, EC, turbidity and multi-parameter sensors, and nutrient analysers.

What an audit covers

  • The site: its hydraulics, access, and the condition of the installation
  • The instrument’s readings against an independent reference measurement
  • For flow meters, the relationship between depth and velocity
  • The logger, power supply and telemetry, so readings keep reaching you
  • A record of findings, adjustments and recommendations

Why it matters

  • Data that stands upReadings that hold up in a model, a compliance report or a capital works decision.
  • Problems found earlyA drifting sensor or a fouled site found at the audit, not months later in the data.
