Flow Switch Principle Of Operation

0 03 m s to 3 m s 0 1 to 9 84 ft s as relative value between 0 and 100.

Flow switch principle of operation.

In the presence of fluid flow controlled movement of the piston actuates an external hermetically sealed reed switch. The induced voltage e is directly proportional to the velocity v of the fluid moving through the magnetic field b. The induced voltage is carried to the transmitter through the electrode circuit. The thermal dispersion principle of operation features no moving parts and provides an extremely reliable and repeatable switch for the most demanding industrial applications.

The tension of the range spring can be adjusted so that it is compressed at a certain pressure or setpoint. This piston is forced upwards by the inlet pressure against the range spring. Thermal dispersion flow switch based on the principle of heat transfer the thermal dispersion flow switch consists of two temperature sensors. The flow principle behind magnetic flow meters is known as faraday s law mathematically defined as e k b d v.

Flow switch working principle. As shown in the sectional view of the pressure switch above the inlet pressure is applied to the bottom of the operating piston. The trip signal will indicate to the pump to turn on or turn off. The principle of operation is based on heat transfer.

Thermal dispersion flow switch is a precise flow sensing device for liquids. Learn more about the technology and operating principles behind gems sensors and controls broad portfolio of sensing products by accessing our operating principles for level pressure flow conductivity relays and barriers and ultrasonic products. Flow switches are mechanical devices used in controlling the flow of air steam or liquid. The fx series flow switch is the most reliable flow switch available.

Aflow switchoperates by conveying a trip motion relay reed switch paddle to another machine within the system usually a pump.
