Series 228/250 Flow Sensors
The Data Industrial Series 228/250 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 than four bladed impeller designs 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 2000' between the flow sensor and the display unit without the need for amplification. All sensors except irrigation versions are supplied with 20' of Belden type 9320 two conductor shielded cable.
Series 228 Tee Sensors
The tee mounted flow sensors consist of a standard 220B or 220SS mounted in a 2" or 2.5" tee:
Model 228B - brass/bronze sensor mounted in a bronze tee.
Model 228CB - brass/bronze sensor mounted in a cast iron tee.
Model 228SS - stainless steel sensor mounted in a stainless steel tee.
Series 250B Tee Sensors
Available in five different sizes (0.5", .75", 1.0", 1.25", 1.5"). Removable sensor mounted in a cast bronze housing.
