GMF701-A 4-20mA RS485 Water acid slurry carbon steel digital flange magnetic electromagnetic flow meter
Product Overview
GMF701-A intelligent electromagnetic flowmeter is a fully intelligent electromagnetic flowmeter developed by our company using advanced technology at home and abroad. Its all-Chinese electromagnetic converter core adopts high-speed central processing unit. The calculation speed is very fast, the precision is high, and the measurement performance is reliable. The converter circuit design adopts international advanced technology, the input impedance is up to 1015 ohms, the common mode rejection ratio is better than 100db, and the interference immunity for external interference and 60Hz/50Hz is better than 90db. It can measure the flow rate of fluid medium with lower conductivity. The sensor adopts non-uniform magnetic field technology and special magnetic circuit structure, the magnetic field is stable and reliable, and the large size is reduced, the repetition is reduced, and the flowmeter is characterized by small flow. It is the tenet of our company to make customers "free to buy, use peace of mind, and serve the heart".

Product Features
1. High-definition LCD display, reading table reading at a glance, backlight display, convenient and fast.
2. Professional head, all the terminals are welded and packaged, and the inside of the instrument case greatly enhances the stability.
3. Imported chips, intelligently filter out interference waves, the value is more stable, and the anti-interference ability is strong.
4. Selected stainless steel electrical interface, good sealing performance, excellent water resistance and long service life.
5. There are no moving parts in the measuring tube, which is convenient for maintenance and management; there is no obstruction part, so there is no pressure loss.
6. The lowest conductivity of the tested liquid is ≥5μs/cm. It can be used with various lining materials to measure and measure the flow of various acids, alkalis, salt solutions and mud, pulp, pulp and other media.
7. The measurement of flow rate is not affected by the change of density, viscosity, temperature, pressure and conductivity of the fluid. The induced voltage signal of the sensor is linear with the average flow velocity, and the measurement accuracy is high.
8. Reasonable use of lining and electrode materials can achieve good corrosion resistance and wear resistance.
9. Low-frequency rectangular wave excitation is not affected by power frequency and various spurious interferences on site, and the work is stable and reliable.
10. Irrespective of the direction of the fluid, the forward and reverse directions can accurately measure the range ratio of 1.120 (0.1m/s - 12m / s), and the full-scale flow rate range is wide. .
11. Chinese and English LCD backlight display, parameters can be modified online, easy to operate.
12. It has the function of air tube measurement and alarm, and can adapt to different fluid media.
13. Power-down time recording function, automatically record the power-off time of the instrument system, and calculate the leakage meter flow.
14. The hourly total recording function records the total amount of flow in hours, which is applicable to the time-sharing system.
