Gas flowmeter specification

Electromagnetic flowmeter is based on principle of karman vortex liquid production is used as the measurement of sealing fluid in pipe, gas, steam flow rate and high precision instrument panel, because the test component in the test body sealing, not material under test, and their inside can't move artifacts, don't have to carry out maintenance on the spot, and by the favor of many customers, is widely used for printing and dyeing, oil, chemical, metallurgical industry, paper-making industry, pharmaceutical industry, thermal power plant, the fire safety metrological verification management method and process of industrial production management

Liquid electromagnetic flowmeter working principle

The electromagnetic induction flowmeter is a flowmeter for flow measurement based on Faraday's law of electromagnetic induction.The advantage of electromagnetic induction flowmeter is that the pressure loss is small, can measure the flow range is large.Large flow and the minimum flow rate of the general part, in the industrial production of available pipe by the scope wide, large, to 3 m output data signal and the measured flow into linear, precision is higher, can measure the conductivity of 5 mu s/cm or more acid, alkali, salt solution, water, waste water, corrosive liquid and drilling mud flow of fluid mechanics, pulp, pulp, etc.But it can not measure the flow of steam, steam and its mineral water.

When the electric conductor in the electromagnetic field for laser cutting magnetic induction line fitness exercise, in the electric conductor will cause the magnetic induction potential, the size of the magnetic induction potential and the reasonable length of the electric conductor in the electromagnetic field and the conductor in the magnetic field for vertical bisection direction fitness movement rate proportional.Similarly, conducting hydrodynamics creates vertical azimuthal fluidity in the electromagnetic field, and laser cutting of the induction coil force lines also creates magnetic induction potential at the electrical levels on both sides of the pipeline.The direction of the magnetic induction potential is determined by the right hand rule, and the size of the magnetic induction potential is determined by the above formula:

E = KBVD

Type:

E- induced potential;

K- coefficients related to magnetic field distribution and axial length;

B- magnetic induction intensity;

V- average velocity of conductive liquid;

D-electrode spacing;(measuring inside diameter)

The sensor takes the induced potential E as the flow signal and sends it to the converter. After a series of digital processing by amplification and transformation filtering, the sensor displays the instantaneous flow and cumulative flow with backlit dot-matrix liquid crystal.The converter has 4 ~ 20mA output, alarm output and frequency output, and is equipped with rs-485 and other communication interfaces, and supports HART and MODBUS protocols.

Classification of liquid electromagnetic flowmeters

There are always two types of closed pipeline and open channel according to the measurement target division.2. According to the principle of measurement, it is divided into the principle of structural mechanics, the principle of thermodynamics, the principle of acoustic materials, the principle of heat, the principle of electron optics, the principle of molecular physics, etc.

It can be divided into total output measurement and flow measurement according to the measurement object, and the instrument panel is called the total output meter and the flow meter respectively.

Liquid flowmeters can be divided into: corrosion resistant flowmeters, differential pressure flowmeters, sodium hydroxide flowmeters, pressurized flowmeters, electromagnetic induction flowmeters, vortex flowmeters in fluid dynamics oscillating flowmeters, quality flowmeters and SST insert flowmeters.

features

Unable to move components, reliable operation, good characteristics, long life.

The measured flow force is steady without immediate contact with the sensor.

Working pressure damage is less, so the gas pressure flowmeter has the characteristics of environmental protection and energy saving.

Simple and strong construction, easy installation, maintenance costs are very low
