Description

Technical Field

[0001] This utility model belongs to the field of flow measurement of metering instruments, specifically a volume correction instrument calibration device. Background Technology

[0002] A gas flow meter generally consists of two parts: a flow meter base meter and a volume correction instrument. Structurally, it can be either an integrated type or a separate type. The error of a gas flow meter consists of four parts: base meter error, pressure detection error, temperature detection error, and display totalization error. The latter three are the main components of the volume correction instrument.

[0003] Currently, volume correctors are a new generation of compensated volume correctors that integrate flow, temperature, and pressure detection functions and can automatically compensate for temperature, pressure, and compressibility factor. Intelligent volume correctors can be easily used with flow meters to achieve volume correction; however, existing volume corrector calibration devices cannot calibrate multiple volume correctors.

[0027] like Figures 1 to 2 As shown, a volume corrector calibration device includes a mounting frame 1. The mounting frame 1 has slide rail assemblies 2 on both sides. Each slide rail assembly 2 includes multiple pulleys 21, which are slidably mounted on the mounting frame 1. Each slide rail assembly 2 includes a slide rail 22, in which multiple positioning plates 23 are inserted. Mounting plates 24 are mounted on the positioning plates 23, and volume correctors 3 are mounted on the mounting plates 24. Multiple placement plates 25 are fixedly connected between two slide rails 22. Temperature sensor interface sockets 4, instrument interface sockets 5, and multiple pressure sensor interface sockets 6 are placed on the placement plates 25. By placing multiple volume correctors 3 on the mounting plates, multiple volume correctors 3 can be calibrated simultaneously, achieving a high degree of automation, high efficiency, and reliability. The volume corrector calibration device is installed inside a high-low temperature aging chamber and is detachably connected to the chamber via the mounting frame for easy assembly and disassembly.

[0028] The temperature sensor interface socket 4, instrument interface socket 5, and multiple pressure sensor interface sockets 6 are each equipped with multiple interfaces 7, allowing simultaneous connection to multiple volume correctors 3 for calibration. Pressure sensor interface sockets 6 are evenly distributed on both sides of the temperature sensor interface socket 4, facilitating both installation on the mounting bracket 1 and connection between the interfaces on the volume correctors 3 and the pressure sensor interface sockets 6. The temperature sensor interface socket 4 is used to mount the temperature sensor of the volume corrector 3 under test. The temperature sensor interface socket 4 is connected to the temperature measuring base inside the high and low temperature aging chamber, allowing simultaneous output of the required calibration temperature for multiple volume correctors 3 under test. The instrument interface socket 5 is connected to an external pulse generator and calculation control unit via wires. The calculation control unit performs verification and calibration operations on the volume corrector 3 under test through the instrument interface socket. A tooling pressure inlet 8 is connected to one side of the instrument interface socket 5, and this inlet 8 is connected to an external air pump via a pressure tap. The tooling pressure inlet 8 allows simultaneous output of the required calibration pressure for multiple volume correctors 3 under test.

[0029] The mounting plate 24 is L-shaped and has multiple heat dissipation holes 241. The volume corrector 3 has a fixing member 31 at its bottom, which is snapped onto the mounting plate 24 for easy disassembly. One end of the slide rail 22 has a positioning pin 221 to prevent the pulley 21 from slipping out. The volume corrector 3 is fixed to the mounting plate 24 with bolts. A communication interface 32 is located on one side of the volume corrector 3. Data interaction between the host computer system and the volume corrector 3 can be achieved through the communication interface, enabling the reading and writing of volume correction data. The volume corrector 3 displays parameters and historical data. A switching button 33 is located on the bottom side of the volume corrector 3. The volume corrector 3 includes a rear seat 34 and a front cover 35, which are connected by bolts. A display screen 351 is located on the front cover 35. Pressing the switching button 33 enables the following functions: a short press switches the main interface of the display screen 351; a long press for about 3 seconds triggers the remote communication function; a long press for about 7 seconds triggers the Bluetooth communication function.
