The UFM-70 FS is a multi-functional ultrasonic flow metering system for non-invasive and non-intrusive flow measurements of liquids and liquid gases in fully-filled tubes. The UFM-70 FS works on the transit-time method and can be supplied with one or two measuring channels. This allows the flowmeter to monitor two separate pipes at the same time.

Also, the UFM-70 FS offers functions for measuring level, energy and pressure flows. This modular flow metering system can be customised for you, with different types of inputs and outputs. The system is provided with an internal data logger and software for recording and downloading the measured values. Thanks to its intuïtieve menu, Setup Wizard and Audible Sensor Positioning Assistant™, the flowmeter and sensors can be properly configured and installed within minutes. Optional transducer versions are available for ATEX-zones.
