manometer: pressure of gas mass flow meter: mass flow rate of a fluid travelling through a tube mass spectrometer: masses of ions, used to identify chemical substances through their mass spectra measuring cup: liquid and dry goods measuring cylinder: volume measuring spoon: a spoon used to measure an amount of an ingredient, either liquid or ...
If it is left open, the pressure measured is relative to air pressure, which is variable. If it is sealed, the pressure measured is the absolute pressure. The tube is sealed during manufacture with the sealed end containing a vacuum. [1] Mercury is a useful material to use in a manometer because of its high density.
H, pressure drop across test piece in pascals measured by the test pressure manometer d , density of air in kilograms per cubic meter ( 1.20 kilograms per cubic meter at standard conditions ) This represents the highest speed of the air in the flow path of a normally shaped port, at or near the section of minimum area ( through the valve seat ...
Pressure sensors can alternatively be called pressure transducers, pressure transmitters, pressure senders, pressure indicators, piezometers and manometers, among other names. Pressure is an expression of the force required to stop a fluid from expanding, and is usually stated in terms of force per unit area.

Gas meter. A gas meter is a specialized flow meter, used to measure the volume of fuel gases such as natural gas and liquefied petroleum gas.Gas meters are used at residential, commercial, and industrial buildings that consume fuel gas supplied by a gas utility.
Duct leakage test in the US. A duct leakage tester is a diagnostic tool designed to measure the airtightness of forced air heating, ventilating and air-conditioning (HVAC) ductwork. A duct leakage tester consists of a calibrated fan for measuring an air flow rate and a pressure sensing device to measure the pressure created by the fan flow.
