Technical parameter requirements
(1) Reference standards:
1.JJG1113-2015 'Regulations on Water Meter Calibration Devices'
2.JJG162-2019 'Cold Water Meter Calibration Regulations'
(2) Main functional requirements:
1. Main functions: The device is a fully automatic camera-weighing water meter calibration platform. After the water meter is clamped, the dynamic image collector automatically enters the meter number and scans it into the system. The device automatically completes the calibration of nominal, boundary, and minimum flow in sequence. The camera reads the water consumption by automatically finding and identifying the plum blossom pointer or the red pointer, and can remove various bubble interference through the jet exhaust method. The PLC automatically collects the data of the calibrated meter and electronic scale, automatically calculates the error, and judges the test results. Save the output data. All calibration data can be stored and backed up in time, and can be queried or deleted at any time. The query function should include data such as time, table number, etc. for quick query.
2. The detection method is automatic reversal mass method verification, and is manually compatible with the start-stop mass method. DN15 is connected with 10 meters in series, DN20 is connected with 10 meters in series, and DN25 is connected with 5 meters in series.
3. The device is a fully automatic detection and calibration platform, and the device accuracy is not less than 0.2 level. The device can detect various flow points of DN15-25 (mm) water meters.
4. The device uses a high-definition color industrial all-aluminum alloy camera sensor or a brand-customized mobile phone to collect mechanical water meter data. It is easy to set the watch, has strong anti-interference ability, high waterproof level, and reliable recognition accuracy. It can identify the red pointer and the plum-blossom needle at the same time, which improves the detection speed and accuracy and can also determine whether there is a wrong installation between each gear inside the water meter counter, and whether there is a problem with the transmission ratio.
5. It can automatically collect data from calibrated meters and standard measuring instruments, automatically calculate errors, judge test results, and save output data. Saved data can be queried at any time.
6. The device is automatically operated by PC, and no manual intervention is required for other operations during the test. The device can automatically collect the signal of the meter under inspection, automatically input it into the PC, automatically calculate the error, and meet the needs of different types of water meter data collection (remote electronic water meters, Internet of Things water meters, LCD digital meters, etc.).
7. The device can display working conditions such as temperature and pressure in real time to facilitate personnel monitoring.
8. The device has a pressure test function and can perform pressure test on the water meter.
9. The entire equipment is made of aluminum alloy profiles and 304 stainless steel.
