Measuring the mass flow of steam with a vortex flowmeter

The vortex flowmeter is a volumetric flowmeter, that is, the fluid Reynolds number is within a certain range, and its output is only proportional to the volume flow.
       The output of the vortex flowmeter has two kinds of frequency signals and analog signals, and the analog output is obtained by f/I conversion on the basis of the frequency output. This conversion is about 0.1% loss of accuracy. Therefore, when measuring steam flow, users prefer to use frequency output.
       The frequency output vortex flowmeter is more popular with users such as the heating company. The other reasons are as follows:
a.Frequency output vortex flowmeter price is slightly lower.
b.Modification of full range of Frequency output Vortex Flowmeter is more convenient ,you only need to follow the prescribed method and perform simple operations on buttons on the programmable flow calculator panel.
c.When you want to know the steam mass flow, if you use the frequency signal of frequency output vortex flow meter to calculate,just need to know the current working conditions of the fluid.The temperature and pressure compensation of the analog output vortex flowmeter only compensates for the error caused by the current working condition deviating from the design condition.Therefore, not only need to know the current conditions, but also need to know the design conditions. 
       The second type of data often causes errors due to data loss due to time lapse or personnel changes. In contrast, frequency output vortex flowmeters do not have this problem.

Electromagnetic flow meter and vortex flow meter What are the differences

图片
        As a professional supplier of flow meter, it is very important to use the flow meter users, talk about two kinds of widely used two flow meters. The first is the electromagnetic flow meter, the second is the vortex flow meter. This is what we often use most of the two flow meters. What is the difference between them before? I will tell you from the following points: 1. Electromagnetic flow meter and vortex flow meter principle is different.    According to the principle of flange electromagnetic induction, a pair of test electrodes are installed on the wall of the tube which is perpendicular to the axis of the measuring tube and the magnetic field lines. When the conductive liquid moves along the axis of the measuring tube, the conductive liquid cuts the magnetic field lines to generate the induced potential. The sensing potential is detected by two sensing electrodes. The value is proportional to the flow rate. The value is E = B * V * D * ...

Precautions for the installation of electromagnetic flowmeter

图片
     The electromagnetic flowmeter is an instrument for measuring the volume flow of the conductive fluid through the electromotive force induced by the applied magnetic field according to "Faraday electromagnetic induction principle". It consists of two parts, the sensor and the converter. It is suitable for measuring the flow of conductive liquid and slurry in closed pipes, such as clean water, sewage, various acid and alkali salt solutions, mud, pulp, pulp and food liquids.With the development of industrial technology, the advancement of agricultural science and technology.Due to its own advantages and characteristics, the use of electromagnetic flowmeter has been increasing every year.  At the same time as the amount of use is increased, the following items must be noted in the installation of the electromagnetic flowmeter:      The electromagnetic flowmeter should be installed in the correct position.     1. Installation method (as...
