The 220B brass water flow sensor and 220SS stainless steel water flow sensor are used in general to measure water flow in metallic or PVC pipes from 2-1/2″ to 40″ (6.4 to 101 cm) size. Each sensor can mount in a 2" NPT pipe saddle or Thredolet®. Positioning nuts on the three threaded retaining rods allow the sensor to be accurately positioned to a standard insertion depth of 1-1/2" 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% of actual flow rate can be obtained between flow velocities of 0.5 to 30 ft/sec. Ideal for Building Automation Systems, BAS, and HVAC applications, the standard 200 Series flow sensors are rated for water temperatures to 221 ℉. For higher temperature requirements, see the SDI Series.
