How to choose intelligent electromagnetic flowmeter?

Intelligent electromagnetic flowmeter is a fully intelligent flowmeter developed using domestic and foreign technology. It is very different from traditional analog or non-intelligent electromagnetic flowmeters produced by other companies. In particular, the reliability, stability, flow meter range, usage functions, lifespan, etc. of the measurement accuracy can be modified. The electromagnetic flowmeter is designed with a Chinese LCD display with backlight and wide temperature range, which is fully functional, intuitive and easy to operate.

Characteristics of electromagnetic flowmeter:

1. Intelligent electromagnetic flowmeter is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity. The sensor induced voltage signal is related to the average flow rate. It is linearly related, so the accuracy is higher.

2. Measurement of unobstructed parts of the pipeline without additional pressure loss; without moving parts, the intelligent electromagnetic flowmeter sensor has a long life.

3. The induced electrical response signal is formed in the space of the entire complete magnetic field and is the average value of the pipe cross-section. Therefore, the smart electromagnetic flowmeter sensor requires a short straight pipe section and a pipe length of 5 times. diameter.

4. The flowmeter sensor part only needs to be in contact with the liquid that only measures the lining and electrodes. Reasonable selection of electrode and lining materials can resist corrosion and wear.

5. The electromagnetic flowmeter converter adopts the world's most advanced single chip microcomputer (MCU) and surface mounting technology (SMT), with stable performance, high precision, low power consumption, zero stability, Parameter setting is convenient. The intelligent electromagnetic flowmeter has a dot matrix Chinese display LCD that displays cumulative flow, instantaneous flow, flow speed, flow percentage, etc.

6. The intelligent electromagnetic flowmeter provides fluid research, short-term magnetic flow, and flow over-standard alarms.

7. Bidirectional measurement system, measurable forward and reverse flow. This smart electromagnetic flowmeter uses special production processes and high-quality materials to ensure long-term stable product performance.

How to correctly select an electromagnetic flowmeter:

Selection is a very important task in the application of flow meters. According to relevant data, 2/3 of electromagnetic flowmeters are used in practical applications. The fault is caused by incorrect selection and installation of the electromagnetic flowmeter, so pay special attention to it.

1. The fluid tested must have a certain conductivity, with a conductivity of 5S/cm.

2. The maximum and minimum flow must match the values ​​in the table below.

3. The actual maximum working pressure should be less than the rated working pressure of the flow meter.

4. The highest and lowest operating temperatures should comply with the requirements specified by the flow meter.

5. Check whether there is negative pressure. If the sensor lining is not properly selected, negative pressure may leak due to deformation of the lining.

6. Based on the flow rate in the above table, you can choose a suitable electromagnetic flowmeter. If the selected inner diameter is inconsistent with the inner diameter of the process pipe, it should be reduced or enlarged.

7. When the pipeline shrinks, it must be considered whether the pressure loss caused by the shrinking pipeline affects the process flow.

8. Considering the price of smart electromagnetic flowmeter,You can choose a small-diameter electromagnetic flowmeter to relatively reduce investment.
