Georg Fischer / GF Signet Ultrasonic Flow Meters
GF Signet ultrasonic flow meters use sound waves as a reliable, accurate, and maintenance-free method to measure the velocity of a fluid from which the volumetric flow rate can be calculated. They feature no moving parts making them more reliable and accurate while providing maintenance-free operation. Best of all, Georg Fischer flow meters like the Portaflow 220 / 330 are portable, compact, and easy to set up.
