The series Impeller 200 flow sensor is an insertion style flow sensor constructed of metallic and non-metallic materials. These sensors are designed for service in corrosive and non-corrosive liquids.
The series can be installed in pipe sizes of 3” up to 40” (special models up to 120”) and includes a special potted version (IR models) for irrigation applications (enabling direct mounting in the earth).

The series 200 flow sensors feature a six bladed impeller design with a proprietary non-magnetic sensing mechanism. The forward swept impeller shape provides higher, more consistent torque and is less prone to be fouled by water borne debris. The forward curved shape coupled with the absence of magnetic drag provides improved operation and repeatability even at lower flow rates. This is especially true where the impeller is exposed to metallic or rust particles found in steel or iron pipes. As the liquid flow turns the impeller, a low impedance square wave signal is transmitted with a frequency proportional to the flow rate. The signal can travel up to 600 m between the flow sensor and the display unit without the need for amplification. All sensors except irrigation versions are supplied with 6 m of Belden type 9320 two conductor shielded cable.
