EDS AVFS™

Engineered for Better Hydraulic Decisions

The EDS AVFS™ (Area Velocity Flow Sensor) is an advanced area velocity monitoring solution developed by Environmental Data Services for continuous flow measurement in wastewater, stormwater and environmental applications.

Purpose built for Australia's demanding operating conditions, the AVFS combines high performance ultrasonic Doppler velocity measurement, precision level sensing and intelligent digital signal processing within a compact, fully integrated sensor.

Designed for both temporary and permanent installations, the AVFS delivers reliable hydraulic data that engineers, operators and asset managers can trust when making critical decisions.

 

Designed for Real World Conditions

Unlike monitoring equipment developed primarily for laboratory environments, the EDS AVFS has been engineered specifically for the challenges encountered in modern water infrastructure, including:

  • Wastewater networks

  • Stormwater systems

  • Open channels

  • Partially filled pipes

  • High suspended solids

  • Sediment transport

  • Debris-prone environments

  • Remote telemetry installations

  • Long-term unattended monitoring

The result is a robust and dependable monitoring platform capable of delivering consistent performance in harsh field conditions.

Optimised 5° Beam Technology

The AVFS utilises a carefully engineered 5-degree Doppler beam geometry, optimised to maximise measurement stability and repeatability.

This design provides excellent performance across both low and high flow conditions while maintaining reliable operation in:

  • Gravity sewers

  • Open channels

  • Partially filled pipelines

  • Environmental monitoring applications

Combined with advanced signal processing algorithms, the AVFS delivers highly repeatable hydraulic measurements across a wide range of operating conditions.

Fully Integrated Architecture

Unlike conventional area velocity systems that require multiple external components, the EDS AVFS integrates sensing technology, processing electronics and communications hardware directly within the sensor body.

This integrated design provides significant operational benefits:

  • Simplified installation

  • Reduced wiring requirements

  • Compact footprint

  • Improved noise immunity

  • Enhanced reliability

  • Lower maintenance requirements

  • Direct RS485 integration

  • Future firmware upgrade capability

The result is a streamlined monitoring solution that is easier to install, maintain and deploy.

More Than Just a Flow Meter

The EDS AVFS has been developed as a complete hydraulic measurement platform, providing access to a wide range of operational and diagnostic data.

Available parameters include:

  • Water Velocity

  • Water Level

  • Instantaneous Flow

  • Average Flow

  • Totalised Flow

  • Wetted Area
