Metrology and calibration guides usually refer to the terms Measurement Standards and Measurement Traceability. Let us find out why these terms are important to metrologists and in what ways are related to one other.
Metrology is a science based on comparisons. A measurement of voltage, length, pressure or force must be compared to a well known and defined value, in order to produce a valid result. When performing comparisons, the existence of references for all measurement quantities is necessary. These references and their derived quantities are defined in the […]
Calibration of gas meters has become a necessity nowadays. Several methods are applied for performing gas meters’ calibration. The most common ones are:
Gas meters can be divided into two categories: displacement meters and flow meters. Displacement meters measure volume directly through periodic filling and emptying of one or more measurement chambers. This is why displacement meters are considered to be volumetric meters. The most common displacement meters are:
