Description
Application
The Prosonic Flow W 400 is an ideal ultrasonic clamp-on flowmeter for safe, cost-efficient, and maintenance-free measurement of both conductive and non-conductive liquids. It provides noninvasive, bidirectional flow measurement regardless of pressure, density, and conductivity, without any interruption to the process. FlowDC technology ensures exceptional installation flexibility, maintaining the specified accuracy with an inlet run as short as 2 x DN, even when flow profiles are disturbed. The special coupling pads make the ultrasonic clamp-on system entirely maintenance-free throughout its lifespan. Heartbeat Technology continuously provides process transparency through diagnostic, verification, and monitoring features, allowing detection of build-up before it impacts operation.
Benefits
- Flexible Mounting: FlowDC minimizes required inlet runs, providing greater installation flexibility.
- Reliable Measurement Performance: Proven sensors combined with a maintenance-free mounting system ensure long-term stable signals.
- Low Capital Investment: Cost-effectiveness increases as the pipe diameter grows, accommodating pipes up to DN 4000 (160").
- User-Friendly Operation: The integrated web server allows complete remote access, and the device’s display provides convenient on-site interaction.
- Transparent Process Insights: Heartbeat Technology, with its built-in diagnostics, verification, and monitoring functions, ensures continuous compliance and process safety.
