A device for introducing a variable resistance of regulating the volumetric flow of gas or air.



Related Terms

MULTIPHASE METER

A device for measuring the phase area fractions and flow rates of oil, gas and water of a multiphase flow through a cross-section of a conduit. It is necessary to specify whether the multiphase meter measures volume or mass flow rates.

MULTIPHASE FRACTION METER

A device for measuring the phase area fractions of oil, gas and water of a multiphase flow through a cross-section of a conduit.

BELLOWS GAS METER

A device for measuring the total volume of a continuous gas flow stream in which the motion of two bellows, alternately filled with and exhausted of the gas, actuates a register.

RESTRICTOR

A device for producing a deliberate pressure drop or resistance in a line by reducing the cross-sectional flow area.

ZERO GOVERNOR

A regulating device that is normally adjusted to deliver gas at atmospheric pressure within its flow rating.

CURRENT-CONTROLLED SWITCH

A semiconductor device in which the controlling bias sets the resistance at either a very high or very low value, corresponding to the off'' and on'' conditions of a switch.

PRESSURE DROP

Resistance to flow created by the element (media) in a filter or other equipment. Defined as the difference in pressure upstream (inlet side of the unit) and downstream (outlet side of the unit).

NOZZLE-CONTRACTION-AREA RATIO

Ratio of the cross-sectional area for gas flow at the nozzle inlet to that at the throat.

IMPEDANCE COMPONENT

  1. Resistance or reactance. 2. A device such as a resistor, inductor, or capacitor designed to provide impedance in an electric circuit.

GAS VOLUME FRACTION (GVF)

The gas volume flow rate, relative to the multiphase volume flow rate, at the pressure and temperature prevailing in that section. The GVF is normally expressed as a percentage.
