1. Determination of range and reference table for flow range of electromagnetic flowmeter

The range of electromagnetic flowmeter is closely related to its type and application conditions. The range and flow velocity characteristics of full tube and non full tube states are different: for full tube electromagnetic flow meters, the inner diameter range is wide, from DN40 to DN300. The slag collapse ratio can reach 1:120, and the flow velocity range is wide, from 0.1m/s to 12m/s, providing great measurement flexibility. In non full pipe conditions, the flow velocity measurement range is limited to 0.05-10m/s, suitable for circular pipes with diameters ranging from DN100 to DN6000mm, and the width of rectangular pipes does not exceed 6m. This type of flowmeter pays special attention to measurement under non full pipe conditions.

2. Do you know how to calculate the flow range of an electromagnetic flowmeter? The calculation of the flow range of an electromagnetic flowmeter is based on Faradays law of electromagnetic induction. When a conductive fluid flows vertically in a magnetic field and cuts magnetic field lines, induced potentials are generated on both sides of the pipeline. The magnitude of this potential is related to the flow velocity of the fluid, the magnetic induction intensity, and the inner diameter of the pipeline. The core principle of a flowmeter is to calculate the volumetric flow rate by measuring the induced potential. The formula is: \ [Q-v=({\ pi D}/{4B}) \ cdot Ex \], where \ (Q-v \) is the volumetric flow rate\ (D) is the inner diameter of the pipeline\ (B) is the magnetic induction intensity\ (Ex \) is the induced potential. When an electromagnetic flowmeter is used for actual measurement, the size of the flow range depends on the design, manufacturing accuracy, and fluid characteristics in the actual application of the instrument. Usually, electromagnetic flow meters have a wide flow range, reaching 20:1 or more, and are suitable for various industrial applications. It should be noted that in order to ensure the accuracy of flow calculation, the measurement conditions of electromagnetic flowmeter need to meet some basic assumptions, including magnetic field uniformity, axisymmetric distribution of flow velocity, non-magnetic fluid, and conductivity uniformity. Only under these conditions, the output signal of the flowmeter is linearly related to the fluid volume flow rate. The specific parameters of electromagnetic flowmeters of different brands and models may vary, so when using them, it is necessary to read the product manual carefully to understand the specific operating conditions and performance indicators. If you have further technical questions, you can consult with the wax manufacturer or professional technicians.
