Highlights
- Measuring Range: 0.1 to 10 m/s (0.3 to 32 ft/s), bi-directional
- Accuracy: ± 3 % of the flow value with a flow rate > 0.3 m/s (1.0 ft/s)
- Specially configured for pure water
- An ultrasonic permanent clamp-on flow metering solution for measuring the flow rate
- Processes can be monitored directly by a higher-level system via 4...20 mA, Modbus, pulse or frequency output
Fields of application
- Ultrapure water measurement
- Flow measurement for heat metering
- Chilled water metering
- Flow measurement for energy metering
- Monitoring of manufacturing processes
- New Water / Glycol Measurement
Details
The GF U1000 is a portable, clamp-on ultrasonic flow meter with a display, based on the time-of-flight measuring principle. It can either be used as a stand-alone flow meter or as an integral part of a control loop. The U1000 is very easy to install: clamp it on to the pipe, connect it to power and enter the pipe diameter. The clamp-on design allows the installation in running systems without opening the pipe, providing minimum downtime and maximum availability.
