DMA15 DMA20 DMA25 DMA50 electromagnetic flowmeter

DMA15, DMA20, DMA25 and DMA50 electromagnetic flowmeters are four different specifications of flowmeters produced by E + H Company, which are widely used in various flow measurement occasions. This article will detail the selection and application scenarios of these four electromagnetic flowmeters.

1. selection

When choosing the right electromagnetic flowmeter, we need to consider the following key factors: measuring medium, measuring pipe diameter, measurement accuracy, working pressure and environmental conditions.

1. Measuring medium

DMA15, DMA20, DMA25 and DMA50 electromagnetic flowmeters can measure liquid and gas media, but the specific applicable media should be selected according to the flowmeter model and specifications. Generally speaking, DMA15 and DMA20 are suitable for smaller pipe diameter measurement, such as water, sewage, acid-base, etc., while DMA25 and DMA50 are suitable for larger pipe diameter measurement, such as oil, natural gas, etc.

2. Measuring pipe diameter

The pipe diameters of the four electromagnetic flowmeters are different and can be selected according to actual needs. Generally speaking, DMA15 is suitable for DN10-DN60 pipe diameter measurement, DMA20 is suitable for DN10-DN80 pipe diameter measurement, DMA25 is suitable for DN40-DN300 pipe diameter measurement, and DMA50 is suitable for DN80-DN600 pipe diameter measurement.

3. Measurement accuracy

The measurement accuracy of electromagnetic flowmeter is very important to the accuracy of flow measurement. Generally speaking, the measurement accuracy of DMA15 and DMA20 is relatively high, reaching an accuracy of ± 0.5, while the measurement accuracy of DMA25 and DMA50 is relatively low, at ± 1%. However, it should be noted that the actual measurement accuracy will also be affected by other factors, such as fluid characteristics, installation conditions, etc.

4. Working pressure

It is very important to choose the right flowmeter according to the actual working pressure. The working pressure ranges of the four electromagnetic flowmeters are: DMA15 is suitable for 0-4.0 MPa,DMA20 is suitable for 0-6.4 MPa,DMA25 is suitable for 0-16.0 MPa, and DMA50 is suitable for 0-32.0 MPa. When selecting, it is necessary to ensure that the selected flowmeter can withstand the pressure of the actual working environment.

5. Environmental conditions

The use of electromagnetic flowmeter environmental conditions is also one of the factors to be considered when selecting. For example, when working in high temperature, low temperature, corrosive and other environments, it is necessary to select an electromagnetic flowmeter with corresponding protection level and material. In addition, for the need for remote control or automation of the occasion, should choose a digital communication interface with electromagnetic flowmeter.

2. Application Scenarios

DMA15, DMA20, DMA25 and DMA50 electromagnetic flow meters are widely used in the following scenarios:

1. Water treatment industry: It can be used to measure the liquid flow of tap water, sewage treatment and other occasions. DMA15 and DMA20 are suitable for smaller pipe diameters, suitable for household or small water treatment facilities, while DMA25 and DMA50 are suitable for larger pipe diameters, suitable for industrial or large water treatment facilities.
2. Oil and gas industry: can be used to measure the flow of oil, natural gas and other media. Due to the characteristics of these media, it is necessary to choose electromagnetic flowmeters with higher pressure tolerance, such as DMA25 and DMA50.
3. Chemical industry: It can be used to measure the flow of corrosive media such as acid and alkali, solvents, etc. In this case, it is necessary to select an electromagnetic flowmeter with corrosion resistance.
