Doppler Flow Meters

The 3000 Series is a Clamp on Flowmeter using the doppler shift principle to obtain a flow measurement.  It is popular in some of the worst flow scenarios where certain inline meters are subject to frequent damage because of solids that erode inline sensors or where there are too many air bubbles in the line.

The EASZ-3000 is a mains powered non -intrusive microprocessor based clamp on ultrasonic flow meter for measuring the flow rate and total volume of liquids flowing through process and effluent pipelines. It is suitable for a wide range of liquids, including aerated water, liquids containing suspended solids, slurries and sludges.

The EESIFLO EASZ-3000 requires fluids with a minimum concentration of 100 ppm of solids or bubbles having minimum size of 100 microns and works on most pipes 1 inch and above.

The flowmeter utilises the non-intrusive Doppler principle to measure the mean velocity and is particularly useful as a fixed flow indicator or as a working tool to establish flow conditions in field or plant installations. Units of measurement available are m/s, ls, lm, lh, m3/sec, m3/m, m3/hr, ft3/h, ft3/s, usgps,usgpm, usgph, usmgd. The unit has built in logic to cut off measurement of flow readings on applications which are not suited for Doppler measurement. Each unit is factory calibrated and ready to install andmeasure flow rates within seconds.
