Flow Switch Principle Of Operation

This piston is forced upwards by the inlet pressure against the range spring.

Flow switch principle of operation.

Measured variable flow velocity of liquid media calorimetric measuring principle temperature rtd optional for two switch outputs or additional analog output measuring range flow. The induced voltage is carried to the transmitter through the electrode circuit. The flow principle behind magnetic flow meters is known as faraday s law mathematically defined as e k b d v. Thermal dispersion flow switch is a precise flow sensing device for liquids.

Cost effective and in stock with same day shipping available. As shown in the sectional view of the pressure switch above the inlet pressure is applied to the bottom of the operating piston. The induced voltage e is directly proportional to the velocity v of the fluid moving through the magnetic field b. Flow switches are mechanical devices used in controlling the flow of air steam or liquid.

Thermal dispersion flow switch based on the principle of heat transfer the thermal dispersion flow switch consists of two temperature sensors. In the presence of fluid flow controlled movement of the piston actuates an external hermetically sealed reed switch. The fx series flow switch is the most reliable flow switch available. 0 03 m s to 3 m s 0 1 to 9 84 ft s as relative value between 0 and 100.

Flow switch working principle. Flow switch operating principle is based on a free floating magnetic piston which responds only to the motion of fluids within the line not to static or system pressures. The thermal dispersion principle of operation features no moving parts and provides an extremely reliable and repeatable switch for the most demanding industrial applications. Aflow switchoperates by conveying a trip motion relay reed switch paddle to another machine within the system usually a pump.

The principle of operation is based on heat transfer.
