Series 228 Metallic Tee and Small Pipe Tee Type Flow Sensors OVERVIEW The Data Industrial Series 228 flow sensors from Badger Meter 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 2,000 feet between the flow sensor and the display unit without the need for amplification. All sensors except irrigation versions are supplied with 20 feet of 2-conductor 20 AWG shielded UL type PTLC 105°C cable. SERIES 228 TEE SENSORS The tee mounted flow sensors consist of a standard 220BR or 220SS mounted in a 2 inch or 2.5 inch tee.
