2. Pressure switch - Wikipedia

   en.wikipedia.org/wiki/Pressure_switch

   A pressure switch will have a hysteresis, that is, a differential range around its setpoint, known as the switch's deadband, inside which small changes of pressure do not influence the state of the contacts. Some types allow adjustment of the differential. [1] The pressure-sensing element of a pressure switch may be arranged to respond to the ...

3. DP cell - Wikipedia

   en.wikipedia.org/wiki/Dp_cell

   A DP cell is a device that measures the differential pressure between two inputs. [1]Example: To measure the pressure difference between a container (or vessel) and the surrounding atmosphere, you may connect 'Hi' port of the DP-cell to a fitting that enters the vessel, using suitable tubing.

4. Pressure measurement - Wikipedia

   en.wikipedia.org/wiki/Pressure_measurement

   Differential pressure is the difference in pressure between two points. Differential pressure sensors are used to measure many properties, such as pressure drops across oil filters or air filters, fluid levels (by comparing the pressure above and below the liquid) or flow rates (by measuring the change in pressure across a restriction ...

5. Flow measurement - Wikipedia

   en.wikipedia.org/wiki/Flow_measurement

   The Dall tube is a shortened version of a Venturi meter, with a lower pressure drop than an orifice plate. As with these flowmeters the flow rate in a Dall tube is determined by measuring the pressure drop caused by restriction in the conduit. The pressure differential is typically measured using diaphragm pressure transducers with digital readout.

6. Mass flow controller - Wikipedia

   en.wikipedia.org/wiki/Mass_flow_controller

   High pressure may cause erratic flow rates. There are many different technologies which can help to measure the flow of the fluids and eventually help in controlling flow. Those technologies define the types of Mass Flow Controllers, and they include differential pressure (ΔP), differential temperature (ΔT), Coriolis , Ultrasonic ...
