The Prosonic Flow W 400 is used for measuring conductive and non-conductive liquids and is the optimal choice for safe, economical, low-maintenance operation. With clamp-on installation and a built-in Ethernet server, installation and operation are very simple. Based on the FlowDC optimization algorithm, it ensures stable design accuracy of the flowmeter, unaffected by the flow conditions inside the pipe. It uses Heartbeat Technology, supporting self-diagnosis, self-verification and self-monitoring functions, and continuously provides fully transparent process information.
Advantages
Based on the FlowDC optimization algorithm, reduces the required upstream straight pipe length of the flowmeter
High cost-effectiveness: the larger the pipe diameter, the lower the cost of use (max. diameter up to DN 4000/160")
High long-term signal stability: installed outside the pipe, maintenance-free
Reliable measurement unaffected by the pipe material: GRP pipes and plastic pipes
Safe operation: equipped with a backlit display with touch key operation, no need to open the device during operation
Trouble-free remote access: supports web server
Uses Heartbeat Technology: comprehensive self-diagnosis, self-monitoring and self-verification
Field of application
Non-contact measuring principle, unaffected by pressure, density and conductivity
Bidirectional flow measurement of water, wastewater, process water and media in hydropower plants
