During the factory inspection of plumbing products such as faucets, angle valves, mixing valves, and pipe fittings, flow testing is one of the most fundamental and critical inspection items. The accuracy and repeatability of flow data directly affect the performance evaluation and quality consistency of the products.
Addressing the typical operating conditions of plumbing flow test benches, a solution utilizing electromagnetic flowmeters based on mature electromagnetic measurement technology is provided for testing equipment, offering a reliable data foundation for the inspection of plumbing products.
Measurement Requirements of the Plumbing Flow Test Bench
The plumbing flow test bench typically uses clean water as the medium to conduct rated flow and flow deviation tests on the products being inspected. It has the following characteristics:
- Frequent low-flow operating conditions, requiring high measurement stability
- Batch testing, demanding good data repeatability
- Fast test cycles, requiring the instrument to respond quickly
- Often integrated with PLC/host computer systems for automatic recording of test data
Application Advantages of Electromagnetic Flowmeters
⭐ High Accuracy and Repeatability
The MFE600-E electromagnetic flowmeter is based on Faraday's law of electromagnetic induction, with no mechanical wear factors affecting its performance. It offers high measurement accuracy and excellent long-term stability. In plumbing flow test benches, it accurately reflects the flow differences of various products under the same operating conditions, meeting the consistency requirements of factory inspections.
- Standard measurement accuracy: ±0.5%
- Optional high-accuracy configuration: ±0.3%
⭐ Pressure Loss-Free Design Ensures True Test Conditions
The instrument contains no flow-restricting structures, so it does not introduce additional pressure loss in the test pipeline. This ensures that the flow characteristics of the plumbing products being tested remain unaffected, preventing systematic errors caused by the measuring device.
⭐ Excellent Low-Flow Measurement Capability
Given the relatively narrow flow range of plumbing products, we have optimized the excitation method and signal-processing algorithm to ensure the flowmeter maintains a stable, continuous output even under low-flow conditions. This makes it particularly suitable for precise flow testing of products such as faucets and angle valves.
⭐ Easy Integration and Adaptability to Test Bench Automation Systems
The electromagnetic flowmeter supports multiple industrial standard signal outputs and can be directly connected to the test bench control system, enabling automatic data acquisition and judgment to improve inspection efficiency.
