Flow Sensors - AC220SS
This sensor mounts in a 2" NPT pipe saddle or Thredolet® for installation in pipe sizes from 2 1/2 " to over 40". Positioning nuts on the three threaded retaining rods allow the sensor to be accurately positioned to the standard insertion depth of 1 1/2 inches into the pipe. When the insertion depth is maintained, and there is at least 10 upstream and 5 downstream diameters of straight uninterrupted flow, an accuracy of +/- 1% of full scale can be obtained between flow velocities of 1 to 30 feet/second.
