Abstract

The invention discloses a precession flowmeter online calibration system and online calibration equipment. The method comprises the steps of 1, temperature transmitter calibration: confirming the range of a calibrated temperature transmitter and the temperature range in a parameter setting list, and after confirming that the upper limit and the lower limit of the temperature range are consistent, carrying out the calibration through a standard temperature sensor (temperature calibrator) according to a JJF1183 temperature transmitter calibration specification, and carrying out the next step after calibration. According to theprecession flowmeter online calibration system and the online calibration equipment, which relate to the technical field of online calibration of flowmeters, the flow is obtained by measuring parameters such as frequency generated by the vortex street generator, the accuracy of the vortex street flowmeter is verified on the basis that the flowmeter is not disassembled, and the accuracy is verified through online calibration in daily production, and the problems that the flowmeter cannot be detached for inspection due to continuous production, and damage in the inspection process is prevented are solved.

Description

technical field [0001] The invention relates to the technical field of flowmeter on-line calibration, in particular to an on-line calibration system and on-line calibration equipment for a precession flowmeter. Background technique [0002] In order to achieve online calibration and detection, the swirling flowmeter needs to have a periodic data storage function and a parameter recording function. During operation, it is only necessary to determine that the vortex generating body is normal, the frequency sensing part is normal, the pressure and temperature sensors are normal, and the circuit board processing, calculation and display capabilities are normal. Then it can be judged that the measurement of this meter is running normally. [0003] Existing swirling flowmeters need to be disassembled for inspection during inspection, but the flowmeters cannot be disassembled for inspection due to continuous production in the existing inspections and are easily damaged during the ...
