Valeport BFM001 & 002 Open Channel Flow Meters
The Valeport BFM001/002 flow meters provide cost effective and reliable flow monitoring in open-channels.
ISCO 4210 Flow Meter
The 4210 Ultrasonic Flow Meter from ISCO is designed to provide flow measurement in a flume or over a weir, with automatic compensation for changes in atmospheric pressure to ensure accuracy.
ISCO 4220 Flow Meter
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.
ISCO 4230 Bubbler Flow Meter
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.
4250 Area Velocity Flowmeter
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.
ISCO 2150 Area Velocity Flow Meter
Continuous Wave Doppler Flow Meter - Ideal for portable flow surveys and Permanent installations.
ISCO 2150EX ATEX Area Velocity Meter
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.
ISCO LaserFlow Flow Meter (MCERTS)
ISCO MCERTS LaserFlow Non Contact Open Channel Flowmeter for ultimate accuracy and minimal maintenance.
