Flow monitor, mechanical

1..90 m/s (adjustable using different paddle lenghts and setpoint knob), relay 24..250 V / 15(8) A, 108 x 73,5 x 70 mm + paddle 29x34...167 mm, screwed socket 1", suitable for liquid and gaseous media up to 120 °C

Datasheet

Mechanical flow control switch indicates liquid or gas flow by a changeover contact in pipes sized 1/2“ to 8“.

  • Indication of media flow at pumps, compressors, chillers, heat exchangers, and other technologies. 

The media flow actuates the measuring paddle which is mechanically linked to the switch. Sensitivity is set by a screw inside of the cover, see table. 

Mind the correct position of the switch in the pipe: install it vertically in a horizontal piping, before and after the switch there should be a calming section of min. 5x pipe diameter.
