The structure of the Low price electromagnetic flowmeter from China manufacturer is improved continuously, and the flow of the measured components is free from electromagnetic interference. It is applicable to the measurement of various corrosive media. Its measurement is not affected by fluid density, temperature, pressure, viscosity, Reynolds number and temperature. It only needs water as the experimental medium for calibration. It has the advantages of large range ratio, high measurement accuracy, no mechanical inertia and sensitive reflection. It can measure pulsating flow and fast cumulative total amount. Many other types of flow meters, such as strong adaptability, are highly praised by the majority of users. Low price electromagnetic flowmeter from China manufacturer is one of the widely used instrument types in recent years.
The main structure of Low price electromagnetic flowmeter from China manufacturer is composed of sensor and converter. It works based on Faraday's law of electromagnetic induction and is used to measure more than 5 μ M conductivity s / cm volume flow of conductive liquid is an inductive instrument for measuring the volume flow of conductive medium.
The standard of protection grade of electrical product shell is as follows:
1. IP65: blowout proof type. The sensor housing of the Low price electromagnetic flowmeter from China manufacturer allows the faucet to spray water to the sensor from any direction of the electromagnetic flowmeter sensor. The water spray pressure is 30KPa, the outlet water is 12.5l/s, and the distance is 3M.
2. IP67: Low price electromagnetic flowmeter from China manufacturer sensor can be immersed in water in a short time.
3. IP68: submersible - suitable for long-term underground operation under water or certain pressure. At this time, the sensor of the Low price electromagnetic flowmeter from China manufacturer is separated from the display part. Modular Low price electromagnetic flowmeter from China manufacturer shall be made, but the protection grade requirements of electromagnetic flowmeter must be emphasized.
The protection grade shall be selected according to the actual situation. If the sensor needs to be installed underground and is often flooded, IP68 should be selected. If the sensor is installed above the ground, IP65 and IP67 should be selected.
The protection grade of Low price electromagnetic flowmeter from China manufacturer is generally IP65, which is suitable for most working conditions. Because of the relationship between the electromagnetic sensor and the flow sensor, the electromagnetic sensor plays a very important role in the flow sensor. If the protection grade of electromagnetic flowmeter sensor is IP65, its installation location must meet the following requirements:
1. Try to avoid the surrounding environment with high concentration of corrosive gas;
2. The ambient temperature is in the range of - 25 / - 10 ~ 50 / 60 ℃, and the temperature of the overall structure is also affected by electronic components, with a narrow range;
3. The relative humidity of the environment is between 10% and 90%;
4. Try to avoid direct sunlight;
5. Avoid being soaked by rain and water;
6. When measuring miscible fluid with Low price electromagnetic flowmeter from China manufacturer, the place that will not cause phase separation shall be selected; When measuring two-component liquid, avoid installing it downstream of uneven mixing; When measuring the chemical reaction pipeline, it shall be installed downstream of the fully completed reaction section;
7. Try to avoid negative pressure in the measuring tube;
8. Select places with low vibration, especially integrated instruments;
9. Avoid large motors and transformers nearby to avoid electromagnetic interferenc
