Reliable Measurement Technology
Unlike conventional open-channel flow meters that rely solely on water level measurement, the CLAP-24 measures the actual mechanical position of a pivoting flap installed within the flow stream.
As liquid flows through the measuring section, hydraulic force causes the flap to open. A precision accelerometer continuously measures the flap angle, allowing the electronic controller to calculate flow rate with exceptional stability and repeatability.
This innovative measuring principle minimizes maintenance while providing excellent long-term accuracy.
