Water Tank Indicator Advantages and Disadvantages
The primary function of a water level indicator is simply to gauge water levels in a water reservoir. However, the device can also be programmable to automatically activate a water filter when levels become dangerously low and automatically refill the water to the proper level. A water level indicator can either be mechanical or electronic. Mechanical indicators are those that use pressure or resistance to detect water level changes. Pressure sensitive indicators use an electrical signal to sense water level changes. Electronic indicators use an electronic relay that senses changes in water pressure. To measure water level with a mechanical water level indicator , the circuit diagram for the device needs to be prepared first. This includes all the connections as well as the source and drain connections for the device. Once the circuit diagram is ready, it can be wired to form a basic layout of the water level indicator. The completed circuit diagram can then be etched onto some t...
