The Badger Meter Series 220 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 waterborne debris. The forward-curved shape, coupled with the absence of magnetic drag, provides improved operation and repeatability 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. All sensors except irrigation versions are supplied with 20 feet of Belden type 9320 2-conductor shielded cable.

The brass and stainless steel sensors (220BR and 220SS options, respectively) are used in most general flow-measuring applications in metallic or non-metallic pipes. The sensor mounts in a 2-inch NPT pipe saddle or Threadolet for installation in pipe sizes from 3 inches to more than 40 inches. Positioning nuts on the three threaded retaining rods allow the sensor to be accurately positioned to a standard insertion depth of 1-1/2 inches into the pipe. When this insertion depth is maintained, and there are at least 10 upstream and 5 downstream diameters of straight uninterrupted flow, an accuracy of ±1.0 percent of full scale can be obtained from flow velocities of 0.5 to 30 feet/second (±4.0 percent of reading within calibration range).

The non-metallic sensors (220PVS option), constructed of non-metallic materials for all wetted parts, are designed for service in corrosive liquids. The metallic trim, in non-wetted areas, is 316 stainless steel. The sensor mounts in a 2-inch NPT thread and may be attached to the pipe with a saddle or other types of mounting hardware.
