How does a gas flow computer work?

The electronic flow computer collects live uncorrected gas or liquid volume through any type of meter and calculates corrected volume and energy. This is achieved by measuring live differential pressure, live flowing pressure, live flowing temperature, and/or by counting pulses from the meter.

How is gas flow measured on a flow meter?

The method usually involves float in a tapered pipe. When the fluid is forced in between the tapered pipe and the float, a differential pressure is generated which causes the float to be moved accordingly. You can measure the flow rate by reading the visual scale of the meter.

What is a gas flow meter?

A flow meter is a precision instrument that measures a pipe’s gas flow rate (or liquid flow). While there are four main meter styles for flow measurement, here are three characteristics to determine flow: Positive displacement meters collect a fixed fluid volume, then release and refill the gas or liquid.

What is the function of flow computer?

A flow computer is a special purpose device which computes a corrected flow based on information derived from raw input signals and stored sensor and fluid properties information. Typical applications include: Computation of Heat Flow, Mass Flow, Corrected Volume Flow typically require a flow computer.

What is gas flow?

Gas flow is the motion of a gaseous fluid. The motion of gaseous fluids can be quantified via several measurement regimes. The focus here will be on the mass flow and volumetric flow regimes. These regimes have both advantages and disadvantages.

How do you calculate gas flow?

R = Universal Gas Flow Constant (1545 ft•lbf/(lb•mol)(°R)) divided by M.W. As an example, let’ss assume that we have dry air flowing at 100 lb/min, 200°F and 24.7 psia.

How do you calibrate a gas flow meter?

Place an aliquot (small portion) of process fluid in a test meter and weigh it for a precise amount of time while it flows 60 seconds. Use a calibrated scale to obtain an accurate measurement of the weight of test fluid. After the test period is completed, divert the test fluid into a discharge container.
