Yesterday, a customer from Heze, Shandong called to purchase a water pipeline flow meter with remote transmission display. The flow rate is 0-15m3/h, the diameter is DN50 PN16RF, the material is 304, the electrode is 316L, the lining is PFA, the output is 4-20mA+HART, the power supply is 24V, the accuracy is 0.5 level, the electrical interface size is 1/2NPT (F) * 2, the explosion-proof grade is ExdIIBT4, and it comes with screws, nuts, washers, etc. There are more than 30 units in total. The delivery time is a bit urgent. We recommended an intelligent electromagnetic flowmeter to the customer and sent them on-site installation photos of intelligent electromagnetic flowmeters purchased by other customers under the same working conditions. We also informed the customer about the intelligent electromagnetic flowmeterWorking principle of electromagnetic flowmeterreasonThe customer was very satisfied with the product advantages and immediately expressed the need to purchase.

Today, let me explain to youWorking principle of electromagnetic flowmeter.

Firstly, let's talk about itWorking principle of electromagnetic flowmeterThe intelligent electromagnetic flowmeter produced by Jiangsu Runyi is an induction instrument for measuring the volumetric flow rate of conductive media. According to the Faraday electromagnetic induction principle, a pair of detection electrodes are installed on the pipe wall perpendicular to the axis and magnetic field lines of the measuring pipe. When the conductive liquid moves along the axis of the measuring pipe, it cuts the magnetic field lines and generates an induced potential. This induced potential is detected by the two detection electrodes, and the value is proportional to the flow rate. In addition to measuring the volumetric flow rate of general conductive liquids, this product can also be used to measure the volumetric flow rate of strong corrosive liquids such as strong acids and alkalis, as well as homogeneous liquid-solid two-phase suspensions such as mud, slurry, and pulp.

Next, let's talk about the advantages of electromagnetic flowmeter products:

1. The structure of the electromagnetic flowmeter sensor is simple, with no movable parts inside the measuring tube and no throttling components that hinder fluid flow;

2. Can measure the flow rate of contaminated media, corrosive media, and suspended liquid-solid two-phase flow;

3. During the measurement process, it is not affected by the temperature, viscosity, density, or conductivity (within a certain range) of the measured medium;

4. The output of an electromagnetic flowmeter is only proportional to the average flow velocity of the measured medium, and is independent of the flow state under symmetric distribution (laminar or turbulent);

5. Electromagnetic flowmeter has no mechanical inertia, sensitive response, can measure instantaneous pulsating flow, and can also measure flow in both positive and negative directions;

6. The range of caliber selection for industrial electromagnetic flow meters is wide.

Finally, let's talk about what parameters customers need to know when purchasing an electromagnetic flowmeter?

1. Measure the medium, temperature, and whether there is corrosiveness

2. Flow range and inner diameter of user pipeline

3. Pressure level

4. Is it displayed on site

5. Working power supply

6. Signal output, communication

7. Do you want explosion-proof

8. Installation method

9. Accuracy level

In summary, the working principle of electromagnetic flowmeter, the advantages of electromagnetic flowmeter products, the technical parameters of electromagnetic flowmeter, and the parameters required for the purchase of electromagnetic flowmeter. When ordering electromagnetic flowmeter produced by Jiangsu Runyi manufacturer, it is necessary to choose the appropriate specifications based on the nominal diameter of the pipeline, flow range, nominal pressure, maximum pressure of the medium, temperature range of the medium, and environmental conditions.
