重要な技術的利点
-
Non-Invasive Maintenance-Free Design: The W 400 measures flow bidirectionally without ever touching the fluid. This eliminates pressure drops and potential leak points. The use of specialized permanent coupling pads removes the need for periodic re-greasing, ensuring the acoustic signal remains stable over the device’s entire lifespan.
-
FlowDC for Compact Installations: Typical clamp-on installations struggle with turbulence caused by elbows or valves. The W 400 features the FlowDC (Flow Discharge Check) function, which compensates for disturbed flow profiles, allowing the meter to maintain accuracy with an inlet run as short as 2 x DN.
-
Scalable Cost-Efficiency: Unlike inline electromagnetic flowmeters, the cost of the W 400 does not increase significantly with pipe size. This makes it an exceptionally economical solution for large-diameter pipes reaching up to 4 meters (160 inches).
-
Heartbeat Technology: This integrated suite provides continuous self-diagnostics. It can detect issues such as internal pipe scaling or sensor misalignment by monitoring signal quality, allowing operators to verify the meter’s health without removing it from the pipe.
-
Integrated Web Server: The W 400 includes a built-in web server, allowing technicians to perform configuration, diagnostics, and data retrieval from any device with a web browser (via WLAN or service interface), greatly simplifying commissioning in hard-to-reach locations.
-
Broad Medium Compatibility: Because the measurement is independent of the liquid’s conductivity, pressure, or density, the W 400 can be used for everything from ultrapure demineralized water to raw sewage and industrial process liquids.
主な用途
