What are the measurement ranges of electromagnetic flow meters?

1、 Electromagnetic flowmeter is a very sensitive flowmeter that can measure the flow rate of conductive liquids. It is also economical and has a diameter of generally DN10-- DN2000. It can measure sewage or corrosive liquids and has a wide range of applications;

2、 Electromagnetic flow meters can only measure volumetric flow rates, with units such as m3/h (cubic meters/hour), L/min (liters/minute), etc. They have pure grinding instantaneous flow rate display and cumulative flow rate display;

3、 The measurement range corresponding to electromagnetic flow meters of different diameters is: (unit: m3/h): DN10:0.03-4.24; DN15：0.06---9.54； DN20：0.12---16.96； DN25：0.18---26.5； DN32：0.29---43.42； DN40：0.45---67.85； DN50：0.7---106； DN65

1.19---179； DN80

1.8---271； DN100：2.28---424； DN125：4.41---662.。。。。。 For more detailed information, please refer to the technical article on the website of Shandong Qiangsheng Automation Technology Co., Ltd.... Www.qszdh.com

2. Readings of liquid flow meters

The reading method of liquid flow meters mainly depends on their type, and the core is to distinguish between instantaneous flow and cumulative flow, and correctly set the medium parameters. 1. General reading steps: Regardless of the type of flowmeter, it is necessary to confirm before reading: - Display unit: Confirm whether the screen displays cubic meters (m ³), liters (L), gallons (Gal), or mass units (kg/t). -Instantaneous flow and cumulative flow: There are usually "Flow Rate" or "Instantaneous Flow" and "Total" or "Cumulative Total" markings on the screen. -Medium parameter setting: For flow mete

rs such as vortex street and electromagnetic flow meters, it is necessary to correctly set the density, viscosity, and other parameters of the measured liquid in the instrument, otherwise the reading will be seriously inaccurate. |Check the mechanical counter or electronic display screen. Pay attention to the influence of viscosity, high viscosity liquids can lead to low readings. ||Electromagnetic | Based on Faradays law of electromagnetic induction, measure the induced electromotive force generated by the cutting of magnetic field lines by conductive fluids. |The reading is not affected by temperature, pressure, or viscosity. Liquid conductivity must be required (such as water, acid, alkaline solution), and pure water and oil cannot be measured. ||Ultrasonic method | calculates flow velocity by detecting the time difference between the propagation of ultrasonic waves in both forward and backward directions. |Divided into external clamp type and pipe section type. The external clip installation is convenient, but the accuracy is relatively low. When reading the age of the eggplant, it is necessary to ensure good coupling of the probe. ||Mass flow meter (Coriolis) | directly measures the Coriolis force generated when a fluid flows through a vibrating tube, which is proportional to the mass flow rate. |Directly measuring mass flow rate yields the most accurate readings and is not affected by changes in the physical properties of the medium (density, temperature, pressure). The cost is relatively high. |3. Common problems and solutions - inaccurate readings or large jumping: Check whether the straight pipe sections before and after the flowmeter meet the requirements (usually the first 10D and then 5D, where D is the pipe
