A water meter test bench is a device used to test the accuracy and performance of water meters. It is typically used to calibrate water meters before they are installed, as well as to check the performance of existing meters. A water meter test bench consists of a set of components that simulate real-world water flow conditions and measure the water meter's output. This allows the performance of the meter to be evaluated and compared against standards and specifications. The test bench can be used to test various types of water meters, including mechanical, electromagnetic, and ultrasonic meters. The results of the tests can be used to identify any issues with the meter and make adjustments to ensure accurate readings.

Benefits for Water Meter Manufacturers
Improved Efficiency: The use of an automatic test bench can significantly improve the efficiency of water meter testing, allowing manufacturers to test a higher volume of meters in a shorter amount of time.
Increased Accuracy: Automatic test benches are designed to provide highly accurate readings, ensuring that each water meter is tested to the same high standards.
Quality Assurance: By using an automatic test bench, water meter manufacturers can be confident that their products meet the required quality standards and specifications, reducing the risk of defects and customer complaints.
Cost Savings: Automated testing can help to reduce labor costs and minimize the need for manual testing and inspection, resulting in cost savings for the manufacturer.
Competitive Advantage: By using the latest technology and equipment, water meter manufacturers can differentiate themselves from competitors and position themselves as leaders in the industry.

Main Function
1. Camera technique is a dynamic imaging method.
2. Could automatically collect the volumetric value of measuring vessel and quantitative data of water meter tested.
3. Could test 10 pcs meters at each time.
4. Could verify continuously each flow point of various water meters automatically as per pre-set flow point.
5. Controller and display indicator could display actual work conditions so that the inspector monitor them at any time.
6. Could calculate error automatically and verify condition as per pre-set parameter. Could print, save, and inquire about various verification data.
7. Could verify DN15-25mm measurement level C and below volumetric and velocity type water meter.
8. Have the function of automatically withstand voltage test and test water meter withstand voltage.
9. Verify up to 1.6MPa(max.2.0MPa)then stop automatically and keep in the required time then auto-recovery.
