The new AVFM 5.0 monitors flow through open channels, partially full sewer pipes and surcharged pipes without a flume or weir, and is designed for municipal storm water, combined effluent, raw sewage and irrigation water. It uses a submerged ultrasonic fouling- and corrosion-resistant sensor to continuously measure both velocity and level. It can be configured with the standard submerged velocity/level sensor, or with submerged velocity and a separate non-contacting ultrasonic level sensor. It includes a backlit flow rate display, a totalizer, three 4-20mA outputs and two control relays. Intrinsically safe sensors and a built-in data logger are optional.
