[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. The embodiments of this utility model are described below with reference to the accompanying drawings.

[0015] like Figure 1-3 As shown, a vertical water meter series automatic calibration device includes a water tank 1, a pressure stabilizing tank 2, several water meters to be tested 3, and a standard container 4. The water tank 1 and the pressure stabilizing tank 2 are connected by a first connecting pipe. A water pump 5 on the first connecting pipe pumps water from the water tank 1 to the pressure stabilizing tank 2. The pressure stabilizing tank 2 and the standard container 4 are connected by a second connecting pipe 6. Several water meters to be tested 3 are mounted on the second connecting pipe 6. On one side of several water meters to be tested 3, a first pressure transmitter 7 for observing water pressure and a first temperature transmitter 8 for measuring water temperature are provided. On the other side of several water meters to be tested 3, a second pressure transmitter 9 for observing water pressure and a second temperature transmitter 10 for measuring water temperature are provided.

[0016] Specifically, this device uses water pump 5 as the power source for water flow, which transports water from water tank 1 to pressure stabilizing tank 2. After the water flow passes through pressure stabilizing tank 2 and the pressure is stabilized, it flows through water meter 3 to be tested to standard container 4. The volume of water flowing through the water meter per unit time is compared with the volume of water collected by the standard container per unit time to obtain the error value of the water meter. The first pressure transmitter 7 and the second pressure transmitter 9 are used to observe water pressure changes, and the first temperature transmitter 8 and the second temperature transmitter 10 measure the water temperature to obtain the water density, which is used for standard volume conversion.

[0017] This application describes a vertical water meter series automatic verification device, which is a water flow standard device based on the static mass method measurement principle. It is an electromechanical integrated automated metrological testing equipment, mainly used for the verification, calibration, testing, and experimentation of the metrological performance of vertical water meters. Its structure and performance technical indicators fully meet the requirements of the national metrological verification procedure JJG 1113-2015 "Water Meter Verification Device", and can trace the measurement value to the national metrological standard according to JJG 1113-2015.

[0018] The device integrates Twin-Time flow measurement technology, S-Flowrate and R-Flowrate flow regulation technology, and Rec-Pump pressure control technology. It is suitable for the verification, calibration and testing of vertical water meters in accordance with JJG 162-2019 "Drinking Cold Water Meters" and GB / T 778-2018 "Drinking Cold Water Meters and Hot Water Meters". When verifying mechanical water meters, the water meter reading is automatically collected by a vision sensor and converted into a digital communication signal for input into the measurement and control system.

[0019] The calibration process of water meter 3 under test is automatically controlled by the measurement and control system. Water meter 3 requires manual installation. After installation and correct setting of relevant parameters as required before calibration, the calibration can be automatically completed by pressing the start button. The calibration data is automatically saved in the database by the computer system, facilitating statistics, analysis, query and retrieval, and providing accurate and reliable data support for continuously improving product quality.

[0020] The device adopts Twin-Time flow measurement technology, and each water meter to be tested has an independent clamp, pressure relief valve and visual sensor. Compared with the traditional start-stop volume method device for calibrating water meters, it can greatly reduce the labor intensity of calibration personnel and improve calibration efficiency by 4 to 5 times.

[0021] The device's measurement and control system adopts Rem-Diagnosing remote recovery technology. When the device becomes unusable due to incorrect parameter settings or computer system errors, this technology can help users remotely identify the cause, quickly restore the system, and provide remote guidance to users.

[0022] In some embodiments, the second connecting pipe 6 includes several U-shaped pipes 11 connected in series. Each U-shaped pipe 11 includes a riser 12. The water meter to be tested 3 is installed on the riser 12. Specifically, several water meters to be tested 3 are connected in series.

[0023] In some embodiments, the second connecting pipe 6 is also provided with a pipe speed regulating valve 13, a float flow meter 14, and a manual valve 15 in sequence. The pipe speed regulating valve 13, the float flow meter 14, and the manual valve 15 are arranged between a plurality of water meters to be tested 3 and a standard container 4.

[0024] Specifically, the pipeline speed control valve 13 is used to adjust the flow rate of water in the pipeline, the float flow meter 14 is used to indicate the flow rate, and the manual valve 15 is used to adjust the on / off state of the pipeline.

[0025] In some embodiments, the bottom of the standard container 4 is provided with a water outlet pipe 22, and the water outlet pipe 22 is provided with a container bottom valve 16. A high-precision electronic scale 17 is provided below the standard container 4. The standard container is used to measure the volume of water passing through the water meter 3 to be tested. The high-precision electronic scale 17 is a standard for calibrating the vertical water meter. In other embodiments of this embodiment, multiple high-precision electronic scales 17 and standard container 4 can be set to increase the measurement range of the equipment.

[0026] In some embodiments, the water tank 1 is mounted on the frame 18, and an electrical control cabinet 19 is mounted above the water tank 1. An electronic scale display screen 20 and an operation display screen 21 are mounted on the side wall of the electrical control cabinet 19.

[0027] Specifically, the side wall of the electrical control cabinet 19 is equipped with an electronic scale display screen 20 and an operation display screen 21. The electronic scale display screen can display the weight, and the operation display screen 21 can be a touch screen for controlling the equipment.
