Product description
production Development
I.Early Working Method:
- Reading and Calculation:
Operators used a stopwatch to time while keeping their eyes fixed on the water meter pointer and the measuring device scale. They manually recorded the water meter's displayed volume and the actual volume from the measuring device, then calculated the error using a formula.
- Disadvantages:
Extremely low efficiency: It took a long time to verify a single meter.
High human error: Visual reading errors and reaction delays in timing directly affected the final accuracy.
Data management difficulties: Records were kept on paper, making them hard to store and trace.
II.Semi-Automated Stage
With the development of motors, pneumatic components, and early electronic technologies, test benches began to move away from purely manual operation.
- Core Feature:
Mechanical operations were automated, but judgment and recording still relied on manual work.
- Main Advances:
Flow Control: Pneumatic or electric valves replaced manual valves, adjusted via control panel buttons, making flow more stable.
Reversing Device: Enabled automatic reversal of the measuring container's water intake, reducing operation steps.
Electronic Measurement: Began using electronic scales as standard instruments to replace glass measuring containers, or combining measuring containers with electronic level sensors to automatically detect water levels, thus improving measurement accuracy
III. Core Feature:
The entire verification process is controlled by a computer, with automatic result judgment, achieving "one-click testing."
- Key Technologies:
Computer Control: Uses a PLC or industrial computer as the control core to precisely manage valves, pumps, and flow.
Machine Vision (OCR Recognition): Cameras automatically capture water meter dials or counter wheels, and computer image recognition software identifies the readings, completely replacing human observation and eliminating human error.
Automated Data Management: Verification data is automatically stored in a database, with the ability to generate reports and print certificates, ensuring data traceability.
- Advantages:
Leap in Efficiency: Verification speed is several to tens of times faster than manual methods.
Extremely High Accuracy: Eliminates human factors, making results more objective and precise.
Greatly Reduced Labor Intensity: Operators only need to install and remove meters; all other tasks are handled by the water meter test bench.
