The induced voltage is carried to the transmitter through the electrode circuit.
Flow switch principle of operation.
The tension of the range spring can be adjusted so that it is compressed at a certain pressure or setpoint.
In the presence of fluid flow controlled movement of the piston actuates an external hermetically sealed reed switch.
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.
Measured variable flow velocity of liquid media calorimetric measuring principle temperature rtd optional for two switch outputs or additional analog output measuring range flow.
Cost effective and in stock with same day shipping available.
The trip signal will indicate to the pump to turn on or turn off.
Flow switches are mechanical devices used in controlling the flow of air steam or liquid.
This piston is forced upwards by the inlet pressure against the range spring.
Flow switch working principle.
0 03 m s to 3 m s 0 1 to 9 84 ft s as relative value between 0 and 100.
As shown in the sectional view of the pressure switch above the inlet pressure is applied to the bottom of the operating piston.
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 induced voltage e is directly proportional to the velocity v of the fluid moving through the magnetic field b.
Thermal dispersion flow switch based on the principle of heat transfer the thermal dispersion flow switch consists of two temperature sensors.
Thermal dispersion flow switch is a precise flow sensing device for liquids.
The flow principle behind magnetic flow meters is known as faraday s law mathematically defined as e k b d v.
The principle of operation is based on heat transfer.
