PFM510
Simply the best digital explicit flow switch.
Hydro-Air PFM510 Digital Explicit Flow Switch adopts the principle of thermal diffusion, which is applied in flow detection to show the value of regional temperature difference corresponds to the size of flow. A heating module and a temperature sensing module are placed in the closed probe.
The temperature difference value of the heat transfer of the probe is closely related to the velocity of the measured medium. When the medium in the pipe flows at a stable velocity, the sensor module receives a fixed value that the heating module senses.
When the flow velocity in the probe changes, the thermal sensing module will send out the temperature difference signal, and it will provide the result of the corresponding velocity.
It does not have any moving parts as compared with mechanical flow switch. It will not fail due to corrosion, fracture, baffle deformation, etc.
