Units of Measure Click to learn what really matters when measuring gas mass flow. One can express gas and liquid flow in volumetric or mass flow rates, and the quantities can be converted between one another if the substance’s density is known. The density of a liquid is primarily independe...
Thermal massflow metersmeasure themass flow based on heat transferfrom a heated element. The gas molecules create the heat transfer; the greater the number of gas molecules in contact with the heated surface, the greater the heat transfer. This flow measurement method depends only on the number o...

In many natural gas engineering calculations, it is convenient to measure the volume occupied by l lb-mole of gas at a reference pressure and temperature. These reference conditions are usually 14.7 psia and 60°F, and are commonly referred to as standard conditions. The standard volume is then...
-4).Designed to check gas flow on Tig or Mig torches. -5).Simply place the tester over the Mig/Tig gas nozzle and the gas flow is measured from the top of the ball, can be used for all gases. -6).Flowmeter tester scaled from 0 - 25 litres per ...
A second possible source of blowby gas is from the oil drain a turbocharger system feeds into the crankcase void; to isolate this source and to measure the volumes produced requires a separate metering device. Blowby flow is highly variable over the full range of an engine’s performance ...
Researchers at NIST have developed a new—and sound—way to accurately measure the rate at which gas flows in and out of a vessel. The technique, which uses acoustic waves to determine the average temperature of the gas ...
