Prosonic Flow W 400 is the ultrasonic clamp-on flowmeter of choice for safe, cost-effective and maintenance-free measurement of conductive and non-conductive liquids. It measures flow noninvasively and bidirectionally, independent of pressure, density and conductivity, and without process interruption. FlowDC makes mounting as flexible as never before. The specified accuracy is maintained at an inlet run of only 2 x DN, even in the case of disturbed flow profiles. Special coupling pads make this ultrasonic clamp-on system maintenance-free during the entire product life cycle. Heartbeat Technology provides continuous process transparency with its diagnostic, verification and monitoring functions. This way, build-up can be detected before it affects operation.
Clamp-on meter with Heartbeat Technology and web server for the water and wastewater industry. Short inlet run thanks to Flow DC. Bidirectional measurement for water and wastewater as well as process water and hydropower plants.
