The YFLD series electromagnetic flowmeter is designed and manufactured based on Faraday's electromagnetic induction principle, and can be used to measure the volume and instantaneous flow rate of conductive liquids with a conductivity greater than 20 μ s/cm. Its special lining requirements can adapt to the flow measurement of various corrosive media, and can measure strong corrosive solutions such as strong acids and bases. It can also be used for the measurement of solid-liquid two-phase suspension solutions such as slurry and mud.

YFLD series electromagnetic flowmeterMeasurement advantages:
1. High measurement accuracy, 0.5 level, good stability performance;
2. The measurement is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity;
3. Measure the flow components inside the tube, with no pressure loss and low requirements for straight pipe sections. Adaptability to slurry measurement;
4. Reasonable selection of sensor lining and electrode materials can achieve good corrosion resistance and wear resistance;
5. The converter adopts a novel excitation method, with low power consumption, stable zero point, and high accuracy. The flow range can reach 150:1;
6. The converter can be integrated or separated from the sensor;
7. The converter adopts a 16 bit high-performance microprocessor, 2 × 16 LCD display, convenient parameter setting, and reliable programming;
8. The flowmeter is a bidirectional measurement system equipped with three integrators: forward total, reverse total, and differential total; It can display positive and negative flow rates and has multiple outputs: current, pulse, digital communication HART;
9. The converter adopts surface mount technology (SMT) and has self checking and self diagnostic functions;
10. The measurement accuracy is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity. The sensor induced voltage signal is linearly related to the average flow rate, resulting in high measurement accuracy;
11. There are no obstructions in the pipeline, so there is no additional pressure loss; There are no movable parts inside the measuring pipeline, so the sensor has an extremely long lifespan;
Due to the fact that the induced voltage signal is formed in the entire space filled with a magnetic field and is the average value on the cross-section of the pipeline, the straight pipe section required for the sensor is relatively short, with a length of 5 times the diameter of the pipeline;
13. The converter adopts microcontroller (MCU) and surface mount technology (SMT), with reliable performance, high accuracy, low power consumption, stable zero point, and convenient parameter setting. Click on the Chinese display LCD to show cumulative flow, instantaneous flow, flow rate, flow percentage, etc;
14. A bidirectional measurement system that can measure both forward and reverse flow rates. Using special production processes and high-quality materials to ensure stable product performance over a long period of time.
