Electronic Water Pressure Switch Circuit
A water pressure switch is designed for sensing pressure of an incoming water flow from a source which may be a booster pump, and compare it with the water pressure inside the tank which is being filled by the booster pump water flow. When the water pressure inside the tank crosses the set threshold relative to the pump pressure, an in-built switch is tripped. The trip switch is configured with the booster pump electrical such that when it trips, the motor halts and prevents the tank from filling above the desired upper threshold. A reverse action is initiated as soon as the water level in the tank reaches below a certain lower threshold. Pressure switches are normally mechanical with their operations, and may not be easy to build or replicate at home by a hobbyist. Even an electronic equivalent of the same which might require a precise pressure sensor could be difficult to implement due to the many intricacies of the system. However a simple alternative for fulfilling the above...
