GF Signet

GF Signet is the measurement and control arm of Georg Fischer's piping systems ecosystem. Unlike standalone instrument brands, GF Signet sensors, transmitters, and controllers are engineered from the ground up to integrate seamlessly with GF's extensive portfolio of plastic valves, pipes, and fittings. 

The product portfolio spans flow sensors (paddlewheel, magmeter, and ultrasonic technologies), pH/ORP and conductivity/resistivity sensors with patented measurement circuitry that eliminates the need for platinum plating, pressure and temperature sensors, level transmitters (ultrasonic and hydrostatic), and multi-parameter controllers including the 9900 SmartPro single-channel transmitter, 9950 dual-channel transmitter supporting up to 8 relays, and 8900 multi-channel controller with plug-in modular I/O.
