Open Channel Flow Meters - Small Channels

The OCM III is a high accuracy ultrasonic flow monitor for open channels to complete system studies. In addition to monitoring flowrate in sewage works, the OCM III can monitor industrial discharge, rainfall/storm water studies, inflow/infiltration studies, and sewer system evaluations. The progr...

The ISCO 2150 Area Velocity Module is ideal for both portable flow surveys and permanent installations such as small streams, waste water effluent and irrigation channels.

The 2150EX Area velocity flow meter is intrinsically safe and is specifically designed for use in Zone 0 and Zone 1 potentially explosive atmospheres under ATEX Directive 94/9/EC.

The 4210 Ultrasonic Flow Meter is designed to provide flow measurement in a flume or over a weir, with automatic compensation for changes in atmospheric pressure to ensure accuracy.

The Isco 4220 Flow Logger measures depth using a differential pressure transducer. The venting system compensates for atmospheric pressure changes automatically and can measure pressure acurately even when covered with sand or silt

The 4230 Bubbler Flow Meter uses a bubble line submerged in the flow channel through which an internal air compressor forces a metered amount of air. By measuring the pressure required to force air bubbles out of the line (which is proportional to flow) flow rates can be determined accurately.

The 4250 Flow Meter's sensor directly measures average velocity in a flow stream with patented doppler technology. This system eliminates the profiling and calibration required by electromagnetic systems by continuously profiling the flow stream.
