In modern industrial production and laboratory testing, the accuracy of flow measurement directly impacts process stability, product quality, and the reliability of scientific data. Flow measurement serves as a “metrological benchmark” throughout production and research. Kaifeng Xinya Instrument Co., Ltd. has independently developed a high-precision liquid flow calibration device that integrates advanced measurement technology, automated control, and multi-scenario adaptability. With custom manufacturing and strict quality control, we provide reliable and accurate flow calibration solutions tailored to diverse industrial requirements, strengthening the traceability of measurement standards.
Dual Calibration Mode – Ensuring Core Accuracy
Our device features a mature dual-calib2/28/2026ration system, combining the Static Mass/Volume Method with the Standard Meter Method, allowing flexible selection based on the tested flow meter’s accuracy and application scenario. This design balances calibration precision with operational efficiency, meeting the varied traceability requirements across industries.
Static Mass / Volume Method
The static mass method uses a high-precision electronic balance as the standard, calculating true flow based on the weight of liquid collected over time and its density. This method is ideal for laboratories and metrology institutes requiring extremely high precision.
The static volume method employs a high-precision standard volume container to measure liquid volume over time. It avoids errors from density conversion, offering a convenient, stable solution suitable for industries like food & beverage and water treatment where volume-based calibration is critical.
Standard Meter Method
The standard meter method employs a high-accuracy electromagnetic flow meter (≥0.2 grade) as the reference, pre-calibrated with a higher-level static mass system.
It allows inline calibration of tested meters without disassembly, saving time, reducing wear, and ensuring reliable data transmission. This method is efficient for industrial batch verification and online calibration scenarios.
Stable Control & Reliable Power – Core of Device Performance
Accurate flow calibration requires stable fluid conditions and continuous power. The system design ensures dual stability in pressure and flow, paired with high-quality pump units to provide consistent, energy-efficient operation.
Stabilization Tank: Buffers pressure fluctuations, maintaining system stability.
Degasser: Removes bubbles to prevent measurement interference and ensures uniform flow.
Flow Regulation: Combined regulating valves and variable-frequency pumps adjust flow for various pipe diameters (DN15–DN1000).
Pump Unit: Low-energy, multi-stage centrifugal pumps provide reliable, low-vibration, energy-efficient power for continuous calibration operations.
Automated Control – Efficient, Professional, Reliable
The calibration device includes a complete computer control system to automate the entire process, reducing human error and improving data reliability:
Single-point, three-point, five-point, and multi-point calibration options.
Flexible calibration setup for different flow meter types: velocity, volumetric, differential pressure, mass, vortex, electromagnetic, and ultrasonic.
Automated data collection, storage, query, and calibration certificate generation. Real-time monitoring of pressure, temperature, and flow ensures a fully closed-loop process from calibration → data → certificate.
ntegrated components include control valves, regulating valves, directional switches, and pressure/temperature transmitters, allowing operators to monitor all parameters and detect anomalies promptly.
