Web1 mrt. 2013 · Gas flow measurements for GC can be divided into three regimes. First are high flows from about 30 cm 3 /min up to 400 cm 3 /min. Flows of this magnitude typically are found in detector fuel or makeup gases and in split–splitless inlets. These flows generally are easy to measure and usually are not subject to large errors.

Flow measurement is the quantification of bulk fluid movement. Flow can be measured using devices called flowmeters in various ways. The common types of flowmeters with industrial applications are listed below: Obstruction type (differential pressure or variable area)Inferential (turbine … Meer weergeven Both gas and liquid flow can be measured in physical quantities of kind volumetric or mass flow rates, with units such as liters per second or kilograms per second, respectively. These measurements are related by … Meer weergeven A primary flow element is a device inserted into the flowing fluid that produces a physical property that can be accurately related to flow. For example, an orifice plate … Meer weergeven There are several types of flowmeter that rely on Bernoulli's principle. The pressure is measured either by using laminar plates, an orifice, a nozzle, or a Venturi tube to create an artificial constriction and then measure the pressure loss of fluids as they pass … Meer weergeven Optical flowmeters use light to determine flow rate. Small particles which accompany natural and industrial gases pass through two laser beams focused a short distance apart in the flow path in a pipe by illuminating optics. Laser light is scattered … Meer weergeven A positive displacement meter may be compared to a bucket and a stopwatch. The stopwatch is started when the flow starts and … Meer weergeven A "variable area meter" measures fluid flow by allowing the cross sectional area of the device to vary in response to the flow, causing some measurable effect that indicates the rate.
