CS2 flow velocity sensors are suitable for continuous measurement of slight to heavily polluted media.
The pipe-shaped sensors are designed for installation in pipes from the outside using a nozzle. Combined with transmitter types such as NivuFlow 750 and an external level measurement the result is a complete flow measurement system.
