Description

(1) Technical field [0001] The invention relates to a volume corrector, in particular to a corrector which can be matched with a turbine flowmeter, a waist wheel flowmeter or a vortex flowmeter. (2) Background technology [0002] Volume correctors are mainly matched with flow meters. For example, FCM type and FC-II type volume correctors are used for gas turbines, roots, precession, vortex, industrial skin watches and other gases with pulse signal output An intelligent secondary instrument designed and produced for the flowmeter, integrating temperature sensor and pressure sensor, with on-site pressure and temperature detection and display, directly converting the volume flow and total volume of the flowmeter to the volume under the standard state Flow and total volume, and has a variety of signal output interfaces. [0003] The volume corrector collects the pulse signal from the flow meter, and calculates the uncorrected volume flow rate according to the set pulse equivalent valu...
