Description
GF Signet 152 321 221 Industrial Vortex Flow Sensor w/ Union Nuts O-Rings Cap Manual
The GF Signet 152 321 221 is an industrial vortex flow sensor designed for liquid flow measurement in thermoplastic piping systems. It uses the vortex-shedding principle — as fluid flows past a bluff body inside the pipe, vortices are shed at a frequency proportional to flow velocity, which the sensor detects and converts to an electrical output. GF Signet (Georg Fischer Signet) sensors of this type are commonly used in process control, water treatment, chemical handling, and general industrial fluid management applications.

Applications
GF Signet vortex flow sensors are used in industrial process piping where accurate, non-intrusive flow measurement is needed in thermoplastic pipe runs. Typical applications include water treatment and distribution systems, chemical process lines, semiconductor fab ultrapure water systems, cooling water circuits, and agricultural or municipal water management. The union-style connection makes installation and removal straightforward without cutting the pipe, and the sensor's compatibility with PVC, PP, and PVDF pipe materials suits a wide range of chemical environments. GF Signet (a brand of Georg Fischer Piping Systems) has been a standard choice for flow sensing in thermoplastic piping since the 1980s, and replacement or spare sensors like this remain in active demand for maintenance of existing installations.
This GF Signet 152 321 221 Industrial Vortex Flow Sensor is new and unused. It comes in the original GF Signet box, which has been opened. All accessories are present and accounted for — union nuts, O-rings, sensor, cap, and manual are included. The sensor itself shows no signs of use or wear.
