The working principle of the milk flowmeter: It is based on Faraday's law of electromagnetic induction. In the electromagnetic flowmeter, the conductive medium in the measuring tube is equivalent to the conductive metal rod in the Faraday test, and the two electromagnetic coils at the upper and lower ends generate a constant magnetic field.
When a conductive medium flows, an induced voltage will be generated. Two electrodes inside the pipe measure the induced voltage generated. The measuring tube is electromagnetically isolated from the fluid and the measuring electrode by means of a non-conductive inner lining (rubber Teflon, etc.).
The milk flowmeter adopts the traditional vortex flowmeter principle to ensure durability, practicability, and long service life of the milk flowmeter, and at the same time, the milk flowmeter has the advantages of high measurement accuracy and good stability.
Applicable to all kinds of milk measuring instruments, the whole milk flow meter system consists of a flow sensor, intelligent LCD host, temperature and pressure compensation components, and instrument valve components.
Milk flowmeter advantages and unique selling points:
1. The most important part of the sensor is the coiled design, and the measurement accuracy is ensured through the strictest real-flow test
2. The signal electrode is thoroughly electrostatically shielded to ensure that the small signal will not be disturbed and the measurement accuracy of low flow rate is guaranteed.
3. The coil is isolated from the outside world to ensure the long-term insulation strength of the coil, which also ensures the long-term measurement accuracy of the sensor
4. All welding processes of the sensor use argon arc welding. Although the cost is high, it can ensure the reliability of welding (welding is the most important production process of the sensor), especially the welding process after installing the coil, using argon arc welding. The welding process ensures that the installed coil is not damaged
5. The ground electrode structure is used to form a balanced electrode plane, which ensures that the entire process of measuring the average speed is limited to the balanced electrode plane, which can eliminate electrical noise interference and provide accurate measurement results.
6. Using customized double shielded cable, programmable frequency low-frequency rectangular wave excitation improves the stability of flow measurement and low power loss
7. The measurement of special medium (such as slurry) adopts high-frequency excitation to eliminate clutter interference
8. Using 16-bit embedded microprocessor, fast calculation speed, high precision, the strong anti-interference ability of all-digital processing, reliable measurement, and high precision
9. Ultra-low EMI switching power supply, suitable for a wide range of power supply voltage, good EMC resistance
10. Use a single circuit board to complete all functional designs, using SMD devices and surface mount SMT) technology, high circuit reliability
11. High-definition backlight Chinese LCD display, showing cumulative flow, instantaneous flow, flow rate, flow percentage, etc.
12. Easy to use, easy to operate, easy to learn, easy to understand, two-way measurement system, with three totalizers inside to display the forward cumulative amount, reverse cumulative amount, and difference cumulative amount respectively
