Open Channel Flow Meters

AVFM 5.0 Area Velocity Flow Meter (Portable version available - Stingray)

The AVFM Area-Velocity Flow Meter measures both Head and Velocity to calculate flow volume in an open channel or pipe. Calibration is simple: enter the pipe ID or channel width and the AVFM automatically computes flow volume and displays the flow rate.

The AVFM sensor mounts inside the pipe or at the bottom of a rectangular channel. No special compounds, tools or hardware are required. The sensor is a completely sealed ultrasonic unit with orifices or ports.

Monitor flow through open channels, partially full sewer pipes and surcharged pipes a flume or weir. Ideal for municipal storm water, combined effluent, raw sewage and irrigation water.

Uses a submerged ultrasonic sensor to continuously measure both Velocity and Level in the channel. The sensor is resistant to fouling and corrosion. It is tolerant of turbulence and high approach velocity. Can be configured with the standard submerged velocity level sensor, or with submerged velocity plus a separate non contacting ultrasonic level sensor.

OCF 5.0 Open Channel Flow Meter

The OCF-IV uses a non-contacting ultrasonic sensor mounted over a flume or weir to measure flow. It is accurate, reliable and verifiable.The separate, watertight electronics/display enclosure is mounted at a convenient location within 500 ft (150 m) of the sensor.

Use the built-in keypad for fast, easy calibration with menu selection of flume or weir and measurement units (e.g. gallons, litres etc.) Calibration values and data logs are passwordprotected and retained during power interruptions. Use the OCF-IV to display flow reports of daily minimum, maximum average and total flow, or to transfer data logs to a PC computer.

The OCF-IV continuously displays, totalizes, transmits and data logs open channel flow.
