Open Channel Flow Measurement for Industrial Wastewater Treatment Plant

Industrial Wastewater Treatment Plant monitors effluent discharges with Pulsar Measurement.

At an industrial wastewater treatment plant in Asia, they needed to carefully monitor effluents and transmit the recorded data to the local government regulator. At the time, they did not have a flow meter installed so there was no way of accurately measuring the flow rate of the treated effluent at the wastewater treatment plant.

After a complete survey of the site, the local Pulsar Measurement partner recommended the AVFM 6.1 Area Velocity Flow Meter.

The AVFM 6.1 uses a submersible ultrasonic sensor that measures both level and velocity of flowing liquid to calculate flow measurement in an open channel or pipe. The unit can measure forward flow up to 6 m/s and reverse flow up to 1/5 m/s. The electronics and software sample and average flow rates to continuously provide stable readings.

The standard 26-million-point data logger was perfect for this application. With the ability to store time and date-stamped flow values at 1-second to 60-minute intervals. Daily flow reports are automatically created where total, minimum, maximum, and average flow rates are displayed on the LCD display. Transfer the log files and daily flow reports to any USB flash drive by connecting to the logger's USB output.

The AVFM 6.1 was easily installed at the open channel and the results allowed the wastewater treatment plant to read and record flow rates of their treated effluent and help provide accurate reports to the local government.
