2. Dry running protection - Wikipedia

   en.wikipedia.org/wiki/Dry_running_protection

   There are three different methods for detection of water shortage: Pressure switch on suction manifold or float switch/electrode relay in the supply tank: Dry-running protection with pressure/level switch. Measurement of inlet pressure in the suction manifold by means of an analogue pressure transmitter: Dry-running protection with pressure ...

3. Pressure switch - Wikipedia

   en.wikipedia.org/wiki/Pressure_switch

   Switch enclosures may also be required to be weatherproof, corrosion resistant, or submersible. An electronic pressure switch incorporates some variety of pressure transducer (strain gauge, capacitive element, or other) and an internal circuit to compare the measured pressure to a set point. Such devices may provide improved repeatability ...

4. Pressure tank - Wikipedia

   en.wikipedia.org/wiki/Pressure_tank

   The pressure switch turns the water pump on when it senses a pressure that is less than P lo and turns it off when it senses a pressure greater than P hi. While the pump is on, the pressure tank fills up. The pressure tank is then depleted as it supplies water in the specified pressure range to prevent "short-cycling", in which the pump tries ...

   Efficiency is optimised by changing the design of the system on both large and small scales. Heat pumps [7] and evaporative cooling [8] are efficient alternatives to traditional systems, however they may be more expensive or harder to implement. The job of an MEP engineer is to compare these requirements and choose the most suitable design for ...

7. Water tower - Wikipedia

   en.wikipedia.org/wiki/Water_tower

   The height of the tower provides the pressure for the water supply system, and it may be supplemented with a pump. The volume of the reservoir and diameter of the piping provide and sustain flow rate. However, relying on a pump to provide pressure is expensive; to keep up with varying demand, the pump would have to be sized to meet peak demands.
