The Badger Meter Series 228 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 waterborne 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 feet between the flow sensor and the display unit without the need for amplification.
The Series 228 features four models. The 228BR consists of a brass sleeve and hex mounting adapter assembly inserted in a 2- or 2-1/2-inch bronze tee.
The 2-inch size includes copper solder adapters for mating to copper tubing. The 228CB features a brass sleeve and hex mounting adapter assembly
inserted in a 2- or 2-1/2 inch Class 150 cast iron tee. The 228SS consists of a stainless steel sleeve and hex mounting adapter assembly inserted
in a 2-inch 316 stainless steel tee. The 228PVC features a modified PVC tee with solvent weld socket end connections, and a removable PPS or PVDF
sensor insert. All models are preset to a specific height.
