Abstract

The invention relates to the technical field of metering equipment, in particular to a filtering and liquid changing device which comprises a liquid discharging pipeline, a flushing pipeline and a liquid injection pipeline, wherein the liquid discharging pipeline is at least provided with a connecting-in end, a power pump and a connecting-out end which are communicated in sequence, and the connecting-in end and the connecting-out end are connected with a waste liquid discharging valve and a waste liquid barrel of the flowmeter correction system respectively and used for discharging waste correction liquid in the flowmeter correction system; the flushing pipeline is used for discharging the filled correction liquid after the new correction liquid is reversely filled through the liquid discharging pipeline to flush the flowmeter correction system; and the liquid injection pipeline is at least provided with a connecting-in end, a power pump, a group of filtering parts and a connecting-out end which are communicated in sequence, and is used for conveying and filtering the new correction liquid to the flowmeter correction system. The device has the beneficial effects that the liquid discharging pipeline, the flushing pipeline and the liquid injection pipeline are arranged, so that liquid discharging, flushing and injection of waste correction liquid and the flowmeter correction system are realized; and the filtering part is arranged, so that impurities in the new correction liquid are prevented from entering the flowmeter correction system.

Description

technical field [0001] The invention relates to the technical field of metering equipment, in particular to a filter liquid changing device. Background technique [0002] When the flowmeter measures the actual fluid, due to the different application conditions of the flowmeter, the basic physical properties such as the viscosity and density of the fluid to be measured, as well as the state of the fluid temperature and flow rate are quite different. It is necessary to use the flowmeter calibration system to calibrate the fluid to be measured Calibrate the flowmeter with liquid to ensure the measurement accuracy of the flowmeter in practical applications. [0003] Therefore, when the flowmeter calibration system calibrates flowmeters with different operating conditions, it is often necessary to replace the corresponding calibration fluid. At present, the method of replacing the waste calibration fluid used by the flowmeter calibration system is manual replacement, that is, op...
