　　2. There are no obstructing flow components or pressure loss inside the measuring tube, and the requirements for straight pipe sections are relatively low;

　　3. Series nominal diameter DN15~DN3000. There are multiple options for sensor lining and electrode materials;

　　4. The converter adopts a novel excitation method, with low power consumption, stable zero point, and high accuracy. The flow range can reach 1500:

　　5. The converter can be integrated or separated from the sensor;

　　6. The converter adopts a 16 bit high-performance microprocessor, 2x16 LCD display, convenient parameter setting, and reliable programming;

　　7. The flowmeter is a bidirectional measurement system equipped with three integrators: forward total, reverse total, and differential total; Can display. Zhuang, reverse flow, and have multiple outputs: current, pulse, digital communication HART；

　　8. The converter adopts surface mount technology (SMT) and has self checking and self diagnostic functions.

　　3、 Selection:

　　1. Determination of applicable traffic range. The selection of instrument diameter is determined based on the flow range. For electromagnetic flow meters, they are generally selected in situations where the flow signal is strong and the instrument can work stably for a long time. We suggest that you choose your instrument diameter based on the flow rate flow comparison table and refer to the actual working conditions. We recommend a flow rate range of 1-3m/s, which is beneficial for the instrument to be in a suitable state.

　　2. Selection of lining and electrodes. In addition to determining the diameter and flow range, electromagnetic flowmeters also need to choose relevant conditions such as sensor lining and matching electrodes to improve their economic applicability. The design unit can choose different linings, electrodes, etc. according to the different media of different users

　　3. Pressure and usage situation. In addition to determining the above conditions, the electromagnetic flowmeter should also improve the selection of operating pressure, installation form, shell protection level, explosion-proof requirements, output configuration, and other usage conditions and conditions. The integrated type is suitable for indoor environments with good performance, while the split type is suitable for situations where the sensor is used in harsh environments, with large pipeline vibrations and high temperature of the measured medium. Please choose according to the instrument model markings.
