Open Channel Flow Meters

Open channel flow meters use an old, reliable technique for measuring water flow rates in channels, streams, and stormwater systems. It is also used in wastewater processing for monitoring effluent discharge. Weirs or flumes concentrate the flow into a known cross-sectional area. The height of the water in the channel, going over the weir or flume, is directly proportional to the flow rate.

    Overview of Ultrasonic Level Sensor 2270

    The type 2270 is a rugged, high performance ultrasonic level measurement sensor, having transducer and processing electronics incorporated in one single housing. Provides all the sophisticated echo detection features of the well accepted 2260 Ultrasonic Level Transmitters.

    For single and multiple tank applications 2-wire sensors are recommended using either HART protocol or 4 to 20 mA for the direct communication with a panel mount controller or a PLC.

    Either for liquid level measurement in sumps or tanks, for tank contents measurement, or open channel flow measurement, the 2270 Level Sensors provide the answer. Sensing ranges up to 8 m are available. PP and PVDF sensor bodies provide best chemical resistance in applications where concentrated chemical shall be detected.
