Metal Electronic Flow Switch-SN11

PREV: Electronic flow switch-SN10B
NEXT: Digital electronic flow switch-SN12

Product introduction

Based on the thermal principle, the sealed probe contains two resistors, one of which is heated to act as a detection resistor and the other unheated to act as a reference resistor. As the medium flows, the heat is removed from the heated resistor and the resistance value is altered, with the difference between the two resistances being used as a basis for determining the flow rate. No moving parts, maintenance-free, easy to install, one model for a variety of pipe diameter requirements, switching volume continuously adjustable, very low pressure loss, compact structure, LED display flow trend and switching status.
