ULTRASONIC DISCHARGE MEASUREMENT SYSTEM FOR WATER TREATMENT AND DISTRIBUTION APPLICATIONS The PQ continuously measures the water or effluent flow through ducts, pipes and open canals in sewer networks, water treatment plants and industrial facilities. It combines two sensors in one system. The first determines the water level by means of a pressure probe or radar sensor, the second simultaneously measures the mean flow velocity with an ultrasonic Doppler sensor. FEATURES Flow velocity range 0.01 … 5 m/s Water level range with pressure sensor up to 10 m Water level range with radar sensor up to 15 m Extremely wide discharge range Versatile installation options Waterproof controller housing that is resistant to aggressive fumes and liquids Simple integration into existing data acquisition and control systems Easily linked to data loggers Multiple data interfaces: RS-485, SDI-12, Modbus, analog, pulse VERSIONS PQ with flow velocity sensor and pressure probe PQ with flow velocity sensor and contact-free radar sensor PV with flow velocity sensor only PLC INTEGRATION The PQ can be easily integrated into a process control unit (PLC) by its digital and analog interfaces.
