flow switch

BROTEK India has all in one, universal, intelligent Thermal flow switch, Its probe with heating element and two temperature sensor, when no flow both thermal sensor has fix temperature difference, and during flow, flow rate is directly proportional of temp. difference of thermal sensors,  Temperature difference signal measuring and control by high precision processor and when its reach at fixed set point switching contact change over,

Heat  switch is mass flow rate switch so its measure and control liquid, air and gas with same precision,
