Transfer Standard Flow Meter
Characteristics of the Transfer Standard The purposes of the comparison lead to the following list of desirable characteristics from the transfer standard listed in nominal order of importance.
Transfer standard flow meter. The master meter is placed in series with the flowmeter under test and the results are compared at different flowrates. Exceptionally durable flow meters and control. Convert volume basis flow rate between several different units.
Standards and criteria for the use of DP flowmeters for custody transfer applications are specified by the American Gas Association AGA and the American Petroleum Institute API. Hence gas flow at normal conditions is calculated as. 20 cfm to cubic metreminute 056634 cubic metreminute.
In a velocity flowmeter the flow is calculated by measuring the speed in one or more points in the flow and integrating the flow speed over the flow area. A master meter must be compatible with the fluid being tested. The most common units to describe standard volumetric flows are standard cubic meters per hour SCMH in metric units and standard cubic feet per minute SCFM in imperial units.
OIML stan-dards are performance based They set quantitative conditions that any custody transfer meter must meet. Fluid motion influences the propagation of these sound waves which may then be measured to infer fluid velocity. Badger Meter flow meters produce consistently reliable performance to ensure proper blending custody transfer and signal transmission as well as compliance with international industry standard requirements.
Of a specific flow meter from field experience. We concentrate on those meters that we use as 1 working standards meters calibrated by NIST and used by manufacturers or secondary laboratories as reference flow meters and 2 transfer standards meters for inter-laboratory comparisons and proficiency tests. The only safe way to guarantee there is no confusion when using normal and standard flow rates is to state what conditions you are using eg.
Therefore it is not based on the primary measurement standards of a government metrology laboratory. For TSI instruments standard conditions are. Flowmeters transfer standards and primary standards.
