Quality systems (gas chromatographs to measure energy content of natural gas and sampling systems for liquid); Calibration using in-place or mobile provers for liquid, or master-meter for liquid or gas; and; Supporting automation. A typical liquid custody transfer skid includes multiple flowmeters and meter provers. Provers are used to ...
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 .
American Petroleum Institute (API) MPMS (Manual of Petroleum Measurement Standards) Chapter 21—Chapters 21.1 - Electronic Gas Systems, and Chapter 21.2 - Liquid Electronic Systems address the ability to audit and verify the information produced by a flow computer, and defines the data which a flow computer should retain, the items which should be audited if modified, the reports which the ...
Note that the m³ gas conversion factor takes into account a difference in the standard temperature base for measurement of gas volumes in metric and imperial units. The standard temperature for metric measurement is 15 degrees Celsius (i.e. 59 degrees Fahrenheit) while for English measurement the standard temperature is 60 °F.
Pressure in blanketed tanks is maintained by self actuating pressure control valves (PCVs). As liquid is withdrawn from the tank the pressure in the gas space falls. The blanket gas supply valve opens to maintain the pressure. As the tank fills with liquid the pressure rises and a vent gas valve open to vent gas to atmosphere or a vent system. [11]
Furthermore, a direct measure of the density of the fluid is obtained. Coriolis measurement can be very accurate irrespective of the type of gas or liquid that is measured; the same measurement tube can be used for hydrogen gas and bitumen without recalibration. [citation needed] Coriolis flowmeters can be used for the measurement of natural ...
Using a dipstick to measure the amount of fuel remaining in a tank The lower end of an oil dipstick with markings for minimum and maximum oil levels. Dipsticks can also be used to measure the quantity of liquid in an otherwise inaccessible space, by inserting and removing the stick and then checking the extent of it covered by the liquid.
Fuel-management systems are used to maintain, control and monitor fuel consumption and stock in any type of industry that uses transport, including rail, road, water and air, as a means of business. Fuel-management systems are designed to effectively measure and manage the use of fuel within the
