Electromagnetic flowmeter is high-precision, high reliability and long service life, therefore, we must be very careful about every aspect in the design of product structure, selection, development process, production assembly and factory testing process. Electromagnetic flowmeter also specially designed with backlight wide temperature of the LCD display, fully functional and practical, intuitive display, easy to use. 4-6 multi-electrode structure, to further ensure the accuracy of measurement and without grounding ring at any time, reducing the size of the instrument and the trouble of installation and maintenance. The diameter of the transmitter is usually selected the same diameter of pipe system. If the piping system is to be designed, the caliber can be selected according to the flow range and flow rate. For the electromagnetic flowmeter, the flow rate of 2-4m / s is more appropriate. In special circumstances, such as liquid with solid particles, taking into account the situation of wear and tear, optional common flow rate ≤ 3m / s.
And two principle of selecting transmitter range:
First, the full-scale of instrument is greater than the expected maximum flow value;
Second, the normal flow is greater than 50% of full scale of instrument to ensure a certain measurement accuracy.
(Integrated intelligent electromagnetic flow meter)
Intelligent electromagnetic flowmeter performance characteristics:
1. Measurement accuracy is not affected by the changes of fluid density, viscosity, temperature, pressure and conductivity, the sensor induced voltage signal and the average flow rate of a linear relationship, so high accuracy.
2. No obstructions in the measuring pipe, so there is no additional pressure loss; there is no moving parts in the measuring pipe, so the sensor has a long life.
3. Since the induced voltage signal is formed in the space filled with the magnetic field, it is the average value of the pipe surface, so the straight pipe is shorter and is 5 times pipe diameter.
4. The sensor part only has the lining and the electrode are contacted with the measured fluid, so just reasonably selects the electrode and the lining material, then it can resist the corrosion and the attrition.
5.LDE converter using the latest international advanced MCU and SMT, reliable performance, high precision, low power consumption, stable zero point, convenient parameter setting . Click the display LCD, shows the cumulative flow, instantaneous flow, flow rate, flow percentage and so on.
6. Two-way measurement system, can measure the positive flow, reverse flow. Using a special production process and high-quality materials to ensure that the stability performance of products in a long time.
