Flow metering inserts CQ4

Range of flow inserts for ISCO Signature bubbler flow meter. They can easily be installed in the pipes up to 300 mm in diameter, swelling the tube.

Rubber and integrated inflation tube
4 models available for circular pipes from 150 mm to 300 mm
Connecting tube and elbow extension available
Accuracy of +/-5% for slopes less than 2.5%
circular and 60° V-notch shaped plate

Flow inserts with circular and V-shaped orifice

Operating principle

Measurement of very low flow rates in free-flow pipes, with choice of contraction type.
Simple to use and highly accurate.
Assemble the poles with the sleeve, connect the tubes to the pump and flow meter, set the zero point using air, then, starting from the inspection chamber, insert the sleeve into the pipe and inflate the rubber air chamber with the pump to ensure a tight seal.
