Micronics UF AV5500 Open Channel Flow Meter

Micronics UF AV5500 utilises a submerged ultrasonic sensor that is installed at the bottom of an open pipe or channel. Exposed materials are stainless steel so the sensor resists fouling and corrosion. Micronics UF AV5500 has no moving parts and no orifices, ports or electrodes.  A local display provides flowrate and total along with 3x 4-20mA outputs for flow, level and velocity. Two onboard control relays can be used for level alarms or low proportionate pulse output for samplers and chlorinators. Micronics UF AV5500 can be calibrated with the built-in keypad and menu system.  A built-in 26 million point data logger with USB output is standard. Intrinsic Safety Barriers for sensor and cable installation in hazardous rated channels is also optional (For Sensor mounting in Class I,II,III, Div. I,II, Groups C,D,E,F,G hazardous locations – unfortunately not European ATEX applications).
