The +GF+ U1000 is a clamp-on (portable) 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.
