2. Pressure measurement - Wikipedia

   en.wikipedia.org/wiki/Pressure_measurement

   Example of the widely used Bourdon pressure gauge Checking tire pressure with a spring and piston tire-pressure gauge. Pressure measurement is the measurement of an applied force by a fluid (liquid or gas) on a surface. Pressure is typically measured in units of force per unit of surface area.

3. Block and bleed manifold - Wikipedia

   en.wikipedia.org/wiki/Block_and_bleed_manifold

   A Block and bleed manifold is a hydraulic manifold that combines one or more block/isolate valves, usually ball valves, and one or more bleed/vent valves, usually ball or needle valves, into one component for interface with other components (pressure measurement transmitters, gauges, switches, etc.) of a hydraulic system. The purpose of the ...

4. Elastomeric pump - Wikipedia

   en.wikipedia.org/wiki/Elastomeric_pump

   Elastomeric pumps, also called balloon pumps or ball pumps, are usually used in the medical field to administer liquid drugs such as local anesthetics, analgesics, cytostatics or antibiotics (depending on the therapy). The required pressure for administering the drug comes from the elastomeric layer that is molded inside the pump.

5. Diaphragm (mechanical device) - Wikipedia

   en.wikipedia.org/wiki/Diaphragm_(mechanical_device)

   A diaphragm pump uses a diaphragm to pump a fluid. A typical design is to have air on one side constantly vary in pressure, with fluid on the other side. The increase and decrease in volume caused by the action of the diaphragm alternately forces fluid out the chamber and draws more fluid in from its source.

6. Metering pump - Wikipedia

   en.wikipedia.org/wiki/Metering_pump

   Pumps used in high-pressure chromatography such as HPLC and ion chromatography are much like small piston metering pumps. For wear resistance and chemical resistance to solvents, etc., typically the pistons are made of artificial sapphire and the ball check valves have ruby balls and sapphire seats.

7. Flow control valve - Wikipedia

   en.wikipedia.org/wiki/Flow_control_valve

   Pneumatically-actuated globe valves and diaphragm valves are widely used for control purposes in many industries, although quarter-turn types such as (modified) ball and butterfly valves are also used. Control valves can also work with hydraulic actuators (also known as hydraulic pilots). These types of valves are also known as automatic ...
