The LevelWizard Open Channel Flowmeter is non-contacting and operates on the principle of timing the echo received from a pulse of sound in air, this provides a highly accurate calculation of flow from the measured head preceding the primary element.
Flow calculations to the British Standard BS3680 are available within the software together with calculations for a wide variety of othern primary elements. Also available within the unit is a customised 32 point calibration routine which also permits the flow measurement of non - standard flumes and weirs.
For channels without primary elements the LevelWizard even offers the facility of connecting a Doppler Velocity Sensor (available from iSOLV) and performing the calculations of Flow Q = Velocity x area for a wide variety of channel shapes.
Open Channel Flow Measurement
It has been specifically designed to measure influent and effluent water flow from all types of municipal and industrial treatment plants.
