Explosion-proof electromagnetic flowmeter

Explosion-proof electromagnetic flowmeter adopts the world's latest technology.Constant current low frequency rectangular wave or two-frequency rectangular wave excitation;It can also eliminate the errors caused by power supply voltage fluctuation, power supply frequency variation and excitation coil impedance variation.It has excellent zero point stability and is not affected by fluid noise.Thus has the high stability, the high reliability characteristic.

Explosion-proof electromagnetic flowmeter features

Extremely strong corrosion resistance, almost any conductive liquid can be measured

Strong anti-interference, almost free from external interference

The measurements are independent of changes in fluid density, viscosity, temperature, pressure, and conductivity

The measurement is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity.

There are no flow obstructing parts and no pressure loss in the measuring tube.

The converter can be integrated or separated from the sensor;

The converter adopts 16 bits high performance microprocessor, 2x16LCD display, convenient parameter setting, reliable programming;

Explosion-proof electromagnetic flowmeter price

The price of explosion-proof type is higher than that of other common type electromagnetic flowmeter, but it is also related to the caliber. The price of different caliber is different, so it should be subject to the field caliber.

Range confirmation

In general, explosion-proof flowmeter for industrial use is appropriate to measure the flow rate of medium 2 ~ 4m/s. In special cases, the minimum flow rate should not be less than 0.2m/s, and the maximum should not be more than 8m/s.If the medium contains solid particles, the usual flow rate should be less than 3m/s to prevent excessive friction between the lining and the electrode.For viscous fluid, the flow rate can be selected to be greater than 2m/s. The larger flow rate is conducive to automatically eliminating the effect of viscous material attached to the electrode and improving the measurement accuracy.

Under the condition that the measuring range Q has been determined, the size of the flowmeter diameter D can be determined according to the range of the above flow rate V, and the value can be calculated by the following formula:

Q = PI D2V / 4

Q: flow rate (㎡/h) D: pipe inner diameter V: flow rate (m/h)

The range Q of the explosion-proof flowmeter shall be greater than the expected maximum flow value, while the normal flow value shall be slightly greater than 50 of the full range scale of the flowmeter.

At present, Shanghai porcelain flowmeter has been exported to more than 100 countries, involved in more than 100 industries.At the same time, the research and development of micro flowmeter also obtained the metrological certification.At home to fill the gap in the micro flowmeter, while breaking the monopoly of foreign enterprises.
