The Intelligent Flow and Speed Measuring Instrument is a high-precision testing device specifically developed for the testing and research of electronic water pumps, cooling pumps, fan motors and servo pumps. It is widely compatible with various comprehensive pump performance test benches and motor performance test systems. The device can simultaneously and in real time measure both the liquid flow rate in the pipeline and the motor’s rotational speed, whilst supporting frequency signal acquisition and data conversion. Combined with high-precision sensor signal processing algorithms, it offers stable measurements, rapid response and high repeatability. Suitable for production line factory acceptance testing, laboratory performance calibration and new product R&D testing, it serves as a core measurement device for pump and motor test systems.
Measurement Functions:
1. Real-time flow measurement: Compatible with frequency-output flow sensors such as vortex flowmeters, it accurately captures real-time liquid flow in pipelines. It supports custom calibration of flow coefficients to accommodate testing conditions involving different pipe diameters and media.
2. High-precision speed detection: Utilising inductive measurement, it accurately reads the motor’s real-time speed, slip, rotor frequency and mains frequency without physical contact, and is suitable for various rotating equipment such as asynchronous motors, brushless DC motors and electric pump motors.
3. Simultaneous display of multiple parameters: Featuring dual independent display windows, flow and speed data are refreshed simultaneously. Users can freely switch between interfaces showing parameters such as speed, slip and frequency to intuitively monitor the equipment’s operating status.
4. Automatic data calculation and processing: Equipped with a dedicated built-in calculation programme, it automatically converts electrical parameter data into core performance indicators such as head, pump efficiency and unit efficiency, meeting the calculation requirements for performance testing under national standards.
5. Data upload and storage: Comes standard with a standard communication interface, enabling integration with industrial control systems and host computer software to facilitate real-time data upload, record storage, graph plotting and report export, whilst supporting full traceability of test data.
Product Advantages：
1. Simultaneous collection of two parameters; one instrument, multiple uses
A single unit simultaneously performs precise measurements of flow rate and rotational speed, replacing traditional split-type instruments. There is no need to combine multiple devices, which simplifies the test bench wiring structure and significantly reduces equipment procurement and operational maintenance costs. It is suitable for various pump and motor testing scenarios.
2. High measurement accuracy; stable and reliable data
The unit achieves a measurement accuracy of up to Class ±0.1. Equipped with digital filtering and intelligent calibration functions, it effectively filters out electromagnetic interference from the workshop and fluctuations in the pipework. It maintains precise measurements even under low-speed and low-flow conditions, with no data drift and excellent repeatability, meeting the standards for high-precision type testing and factory acceptance testing.
3. High adaptability and simple, convenient commissioning
The unit features built-in customisable settings for flow coefficients, motor pole pairs and rated speed, allowing rapid adaptation to pumps and motors of different specifications. The user interface is simple and intuitive; no complex commissioning is required—it is ready to use straight out of the box, making it suitable for high-frequency batch testing on production lines.
4. Industrial-grade stability, suitable for long-term workshop operation
Featuring an industrial-grade main control chip and anti-interference circuit design, the unit boasts a robust, dust-proof and shock-resistant structure. It is suitable for long-term continuous power-on testing in workshop environments, as well as high and low-temperature test conditions, ensuring stable 24/7 operation with a low failure rate and long service life.
5. Seamless integration with the complete test system
Supports standard serial port communication and can be directly connected to industrial PCs and PLC control systems. It works in conjunction with electrical parameter analysers and pressure/temperature modules to automatically complete the entire performance testing process, including data fitting and curve generation, thereby achieving full automation of the test workflow.
V. Applicable Scenarios：
This equipment is widely used in conjunction with comprehensive electronic pump test benches, water pump performance test benches, fan motor test systems and servo module test equipment. It is suitable for factory-exit 100% inspections, batch sampling inspections, new product R&D calibration, type testing and performance data analysis of automotive electronic pumps, cooling water pumps, domestic booster pumps, industrial circulation pumps and various types of fan motors. It serves as standard testing equipment for pump manufacturers, quality inspection laboratories, and research institutions.
VI. Product Services and Support：
The equipment supports customisation for non-standard parameters and software integration, and can be configured with bespoke data templates and report formats to align with the customer’s testing processes. The manufacturer provides on-site commissioning, equipment calibration, operator training, lifetime technical support and after-sales maintenance to ensure the long-term, accurate and stable operation of the equipment, thereby supporting enterprises in standardised quality control.
