Abstract

The invention relates to the technical field of natural gas metering, and discloses a CNG calibrating device. The CNG calibrating device comprises a flow sensor, a flow transmitter, a pressure gage, a gas adding machine detected gun connector, a stop valve and at least one gas receiving bottle opening. The flow sensor is connected with the flow transmitter. The gas adding machine detected gun connector is connected with the flow sensor through a pipeline. The stop valve is arranged on the pipeline. The gas receiving bottle openings are connected with the flow sensor and the pressure gage. The invention further discloses a CNG calibrating system and a field calibrating method. The CNG calibrating device is connected between a CNG adding machine and an automobile gas storage tank (or other gas storage tanks) in series, the device records the actual flow of gas adding of the gas adding machine, and calibration of the metering accuracy of the CNG adding machine is achieved accordingly.

Description

technical field [0001] The invention relates to the technical field of natural gas metering, in particular to a CNG on-site verification device, system and on-site verification method. Background technique [0002] With the development of the national economy and the improvement of people's living standards, environmental protection has been paid more and more attention. In cities, natural gas, which is a clean energy source, has been widely used as a vehicle fuel, and compressed natural gas (CNG) filling machines for filling natural gas into vehicles have been fully used in CNG filling stations. As it involves trade settlement, in accordance with the requirements of the National Metrology Law, mandatory verification of CNG filling machines should be implemented. The establishment of the CNG dispenser verification device is to ensure the accuracy and reliability of the measurement of the CNG dispenser, to ensure the implementation of the measurement method in the field of C...
