Abstract

A gas flow stand (200) is provided according to an embodiment of the invention. The gas flow stand (200) includes a weighing device (210) and a meter (203) for testing positioned on the weighing device (210). The gas flow stand (200) further includes a gas source (201) positioned on the weighing device (210) and a conduit (205) connecting the gas source (201) and the meter (203) for testing. The weighing device (210) generates a weight measurement value for the meter (203) for testing, the gas source (201), and the conduit (205).

Description

technical field [0001] The invention relates to a gas flow test bench. Background technique [0002] Gas metering is used in a variety of applications to measure and / or control gas volumes. A variety of manufacturing and production operations involve gas metering, where one or more gases are metered as they enter a manufacturing process or as they exit a production process. Mass flow meters are used to measure and / or meter out precise quantities of gases. The accuracy of the mass flow meter is therefore very important. [0003] Manufacturers of mass flow meters typically calibrate their meters before they are shipped to consumers. Calibration can include many types of calibration procedures and equipment. One common method of calibration is to compare the gas flow measurements produced by the meter under test to known, highly calibrated mass flow measurements of the same flowing gas stream. As a result, the meter under test can be compared to known measurement standards...
