Datasheets

Non-contact ultrasonic sensor that measures the liquid level in an open channel or upstream of a weir; the flow rate is derived from the geometry of the channel or weir. The measuring range and accuracy therefore depend on the channel or weir used. The instrument is 2-wire powered and features a 4…20 mA output, relay, LCD display and programming unit.

Features

Threaded connections G 1 ½, G 2, 1 ½" NPT, 2" NPT or flange DN80, DN125, DN150 / ANSI 3", 5", 6"
Polypropylene connections
Maximum pressure 3 bar absolute, maximum temperature 90 °C
Power supply 12…36 V DC, 2-wire
4…20 mA output and relay
LCD display and programming unit

Applications

Flow measurement in discharge channels, treatment plants and wastewater or irrigation networks using Venturi flumes or weirs.
