Flow switch GENERAL CHARACTERISTICS The flow switch CR type is designed to control the flow in pipes from DN25 to DN200. The simple installation and robustness make the instrument suitable for use in industrial plants, air conditioning and heating. The paddle has a displacement proportional to the flow that invests itself, this displacement is transmitted mechanically to a microswitch. The calibration is adjustable via an adjustment screw located inside the housing. Standard accessories of the instrument are 3 paddles for pipes from DN25 to DN80, a fourth paddle, optional, can be provided for diameters larger than DN 100. ● ● ● ● ● Low pressure loss. Adjustment of the switch point. Metal bellows seal. SPDT Microswitch 250V - 5A Can be used from DN25 to DN200 TECHNICAL DATA Process connection Accuracy Medium temperature  15% F.S.
