2. Pressure switch - Wikipedia

   en.wikipedia.org/wiki/Pressure_switch

   Uses of pneumatic pressure switches include: Switch a household well water pump automatically when water is drawn from the pressure tank. Switching off an electrically driven gas compressor when a set pressure is achieved in the reservoir; Switching off a gas compressor, whenever there is no feed in the suction stage. in-cell charge control in ...

3. 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 ...

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 ...

5. Pressure measurement - Wikipedia

   en.wikipedia.org/wiki/Pressure_measurement

   Some pressure sensors are pressure switches, which turn on or off at a particular pressure. For example, a water pump can be controlled by a pressure switch so that it starts when water is released from the system, reducing the pressure in a reservoir.

6. Water tower - Wikipedia

   en.wikipedia.org/wiki/Water_tower

   The upper portion of water is skimmed off the top for everyday use while the water in the bottom of the tower is held in reserve to fight fire. When the water drops below a certain level, a pressure switch, level switch or float valve will activate a pump or open a public water line to refill the water tower. [7]

7. Pump - Wikipedia

   en.wikipedia.org/wiki/Pump

   The device uses the water hammer effect to develop pressure that lifts a portion of the input water that powers the pump to a point higher than where the water started. The hydraulic ram is sometimes used in remote areas, where there is both a source of low-head hydropower, and a need for pumping water to a destination higher in elevation than ...
