USM area velocity flow meter
Wastewater / effluent
Wall-mounted USM AV flowmeter for measuring flow in open channels, surcharged pipes and partially full sewer pipes without the need for a flume or weir. Ideal for fast and simple measurement of municipal storm water, sewer flow, waste water flow and irrigation flow.
The area velocity principle uses a submersible sensor fixed to the bottom of a pipe or channel that measures flow velocity and depth. By entering the channel dimensions the volumetric flow in the channel or pipe is computed and instantaneous flow and totalised volume is displayed.
With a 3” vibrant LCD graphics display and a 4-button interface, programming is extremely simple and user-friendly in both metric and imperial units. The USM-AVF comes complete with a 20-year internal datalogger, 4-20mA output, RS485 Modbus communications port and 3 fully programmable relays.
