As an important measuring tool in water resource management, water meters play a key role in daily life. They not only record the water consumption of households and businesses, but also directly affect the calculation of water fees and the rational allocation of resources. However, over time, the accuracy of water meters may be affected by factors such as wear and aging, which may lead to measurement errors. Therefore, regular testing and calibration of water meters is a necessary step to ensure their accuracy and fairness.
Based on the traditional water meter detection method, the development of modern technology has spawned an innovative device, the fully automatic water meter test bench. This device has greatly improved detection efficiency and accuracy through automation and intelligent means, becoming a major breakthrough in the field of water meter detection.
1. In what fields is the fully automatic water meter test bench used?
- Water supply company
Water companies rely on water meters to accurately record users' water consumption to ensure that water bills are charged appropriately. As the water supply network expands and the number of users increases, so does the workload and complexity of manual inspection of water meters. The fully automatic water meter test bench can accurately test and calibrate a large number of water meters in a short time, significantly improving detection efficiency and accuracy.
- Water Meter Manufacturer
For water meter manufacturing companies, product quality is directly related to brand reputation and market competitiveness. The fully automatic water meter test bench provides manufacturers with an efficient and accurate detection method. During the production process, manufacturers can use the testing bench to conduct strict factory inspection on each water meter to ensure that the product meets national and industry measurement standards before leaving the factory.
- Quality supervision department
Quality supervision departments and other government agencies play an important role in ensuring that water meters sold on the market meet measurement standards. The fully automatic water meter test bench provides these departments with a reliable tool for monitoring and managing water meter quality in the market. By regularly conducting random inspections and calibrations of water meters circulating in the market, supervisory agencies can promptly discover and correct substandard products and ensure that consumers' legitimate rights and interests are not infringed.
2. How about S.H.Meters' fully automatic water meter test bench?
Since 2013, S.H.Meters has been engaged in the research and development and sales of fully automatic water meter test benches. After years of technical accumulation and market research, S.H.Meters has continuously improved the design and function of its products to meet the needs of users in different industries.
Why did S.H.Meters get involved in the production of water meter test benches?
We develop water meter test benches to provide customers with higher quality products and more accurate measurement services. Through independent research and development of test benches, companies can ensure that water meters are strictly tested before leaving the factory, improving the reliability and accuracy of products.
Once launched, S.H.Meters' fully automatic water meter test bench quickly attracted widespread attention in the industry. With its excellent performance and reliability, it has been widely used around the world and has been exported to Serbia, Saudi Arabia, Botswana, Vietnam and other countries. However, we have also received feedback from customers that the test bench has problems such as unstable water pump flow, uncontrolled pneumatic valves, or leaking meter clamping pipes. If the test bench you purchased has these problems, please contact us and we provide after-sales service.
3. What is a fully automatic water meter test bench?
The fully automatic water meter test bench is an efficient device for testing and calibrating water meters, with multiple core functions.
- First, it can detect the flow of water meters to ensure the metering accuracy of water meters under different flow conditions.
- Second, the test bench can perform precision calibration, and adjust the metering accuracy of water meters by accurately measuring the difference between the reading of the water meter and the actual flow to ensure that it meets industry standards.
- In addition, the fully automatic test bench also has data recording and analysis functions, which can automatically record the data of each test and generate detailed reports. These data not only help quality control, but also provide reference for subsequent maintenance and management.
The fully automatic water meter test bench realizes the automatic detection of water meters through a series of precise sensors and control systems.
4. What are the components of the fully automatic water meter test bench?
- Water pump
The maximum flow rate is 8 m³/h, and the head is 100 m. It is controlled by a Danfoss inverter, with different frequencies set by software. An airbag-type pressure-stabilizing tank is installed in the pipeline to reduce flow disturbances. For Q2 and Q1 flows, a piston water supply is used for stable flow.
- Water tank
Made of 304 stainless steel, with a volume of 500 L. A liquid level sensor is installed at the bottom to measure the water level, which is monitored by the software system. It has an electric heating device, with temperature control accuracy of ±1°C, and an outer insulation layer.
- Piston
The active piston liquid flow device consists of a piston rod, cylinder, and motor. Flow is measured in a sealed cavity by the movement of the piston rod. It is divided into piston and plunger types. The plunger type has a simpler structure, better sealing, higher accuracy, and is more suitable for use.
- Clamping pipeline
The inspection pipeline includes a clamping device, pipelines, and switch valves. The clamping device adjusts spacing for various water meters and uses an external cylinder mechanism to prevent leaks. It is positioned on a precision stainless steel plate using three optical axes for high coaxiality.
- Flow regulating device
Equipped with three flow point pipelines and two electromagnetic flowmeters for displaying flow below and above 250 L/h. Pneumatic ball valves control the selection of flowmeters. The software adjusts flow based on set parameters by modifying the pump frequency or valve opening.
- Electronic scale/electromagnetic flowmeter
The device uses internationally recognized brands. The METTLER TOLEDO 120KG/6000E electronic scale is mounted outside the main body to reduce vibration errors. Calibration is easier, and an electromagnetic flowmeter can also be used.
- Flow control valve
When the detection flow is in the range of 500L-8000L, the device can be equipped with a Samson pneumatic control valve with a flow control accuracy of <2%. When the detection flow is below 500L, a piston is used to automatically push out a stable flow.
- Commutator
Uses a flap-type commutator for flow switching with small vibration and fast switching. Uncertainty is better than 0.05%. Pre-installed sensors enable flow switching and error detection by the commutator time difference method.
- Image acquisition system
Advantage 1: The image acquisition range is wide, and no special alignment is required. As long as the dial pointer is within the range of the collected picture, it can be recognized.
Advantage 2: It can be verified twice. After the detection, the software will automatically save the initial and final value photos. If there is any objection to the detection result of a certain meter, you can query the saved pictures for review.
Advantage 3: High acquisition accuracy, acquisition error is 0.001L.
Advantage 4: Easy installation. The camera uses a POE-powered Ethernet industrial camera. It only needs one network cable to connect to the switch, and the switch network cable is connected to the computer network port.
- Software control system: software part
The verification system is written in C# and runs on .NET Framework and .NET Core. C# is compiled into intermediate code (MSIL) and executed through the .NET Framework's CLR. The code is converted into binary machine code at runtime and stored in the buffer for efficiency.
- Software control system: hardware part
The control system includes an industrial computer, PLC control, servo motors, grating rulers, sensors, valves, and platform software. The industrial computer is highly resistant to interference, making the process stable. The PLC and servo motors are high-precision, reliable, and from well-known brands.
