The Impeller 220 PVCS flow sensor is an insertion style flow sensor constructed of non-metallic materials for all wetted parts. These sensors are designed for service in corrosive fluids. The metallic trim, in non-wetted areas, is 316 stainless steel. The sensor mounts in a 2" NPT thread and may be attached to the pipe with a saddle or other types of mounting hardware.

The 220 PVCS sensor features a six bladed impeller design with a proprietary, non-magnetic sensing mechanism. The impeller shape coupled with the absence of magnetic drag provides consistent accuracy and repeatability throughout the flow range of the sensor. As the liquid turns the impeller, a low impedance signal is transmitted with a frequency proportional to the flow rate. This signal can travel up to 600 m (2000 feet) between the sensor and the display unit without the need for amplification.
