Area Velocity Open Channel Flow Meter

The Pulsar Measurement AVFM 6.1 is an open channel flow meter with a submergible ultrasonic sensor, which is capable of measuring the flow of liquids through open channel systems, partially filled pipes, and surcharged pipes without a flume or weir.  The sensor is resiliant to fouling, corrosion and abrasion. The AVFM 6.1 can be configured with only the standard subermergible sensor, or with a separare non-contacting sensor for highly aerated fluids,  or fluids with a high concentration of suspended solids. The flow rate and total flow can be viewed on the device's backlit LCD display. 3 x 4-20mA outputs and 2 control relays are provided for connection to external devices. Flow rate, volume, run hours, and diagnostic information is available through the optional Modbus RTU serial communications.
