Technical Field

[0001] The utility model relates to the technical field of flow meter verification and calibration tools, in particular to a portable tool integrated vehicle for flow meter verification and calibration. Background Art

[0002] Flow meters are used in trade measurement and delivery in various fields. Since the density of fluids such as natural gas varies with temperature and pressure, the flow meter indication will also change. When the flow meter is used in a specific environment, the directly measured indication must be multiplied by the instrument constant, and the volume flow rate under the working state must be converted to the volume flow rate under the standard state before it can be used as the standard measurement indication of the flow meter. The work of determining the instrument constant is the flow meter verification and calibration. The process of flow meter verification and calibration is an existing technology.

[0003] Verification and calibration are usually carried out at the verification station or verification point. During verification and calibration, the temperature and pressure under working conditions need to be determined, so the temperature transmitter and pressure transmitter also need to be wired. The signal wiring workflow for flow meter verification and calibration is usually as follows: the verifier first wires the flow meter, temperature transmitter and pressure transmitter respectively, and then connects the signal cables of the flow meter, temperature transmitter and pressure transmitter to the explosion-proof wire box of the flow meter.

[0004] In the signal wiring link of flow meter calibration, different tools such as wrenches, screwdrivers, and multimeters are usually needed to load and unload explosion-proof wire boxes, flow meters, temperature transmitters, and pressure transmitters. The tools are frequently used and placed in a messy manner. At the same time, when wiring, due to the many tasks of the calibration instrument, there are also multiple signal lines such as flow meters, temperature transmitters, and pressure transmitters. There are many signal lines on site and the cables are messy, which makes the wiring complicated and the work efficiency relatively low. Utility Model Content
