How to install electromagnetic flowmeter quickly
Electromagnetic flowmeter is used in industrial production at ordinary times or quite common, in view of the friend that does not master, installation is a very painful thing, so installation electromagnetic flowmeter after all what method does have, how can ability install below announce answer to a riddle for everybody
How to install electromagnetic flowmeter quickly and easily
Installation of inductor
1) when measuring the fluid dynamics of the mixed phase, select the site that is not easy to cause the phase separation;When measuring liquids at room temperature, prevent them from being mixed or unsymmetrical
In the middle and lower reaches.When measuring the chemical change pipeline, it should be installed in the middle and lower reaches reflecting the sufficient progress section.
2) try to prevent the change of air pressure in the measuring tube;
3) avoid large peripheral motors and large transformers to avoid the influence of magnetic field;
4) try to avoid corrosion vapor with high concentration in the surrounding environment;
5) try to prevent direct sunlight;
Second, the installation of straight pipe section provisions
First notice that the sensor itself can not be used as a load fulcrum, it can not support the point adjacent to the work of the pipeline, should clamp its pipe load.In order to obtain all normal measurements of ** degree, the upper and lower reaches of the electromagnetic induction heat meter also have a certain length of straight pipe segment, but its length is lower than that of most other instruments.90 ° bend pipe, t-shaped pipe, reducing pipe of the same boat, opening the full stop valve need to be 5 times straight from the inductor inlet end lov flange face (5D) length of straight pipe segment, different tubing pressure valve must be 10D;The middle and downstream straight sections are (2 ~ 3) D.However, avoid disc valve pump shell into the sensor measuring tube.The distance between the upper, middle and lower straight pipe sections as specified in the standards or the technical specifications for metrological verification is also inconsistent. The convergence is shown in table 2, and the provisions are higher than the general provisions.It is due to ensure that today's 0.5 level precision dashboard requirements are met.
Installation position and fluidity position
The center line of the measuring metal electrode must approximate the horizontal bearing.
The measuring pipe must be completely filled with liquid;
The front ** of the steam flowmeter should have less than 5xD(D is the inner diameter of the steam flowmeter) length of the straight pipe section, the rear ** should have less than 3xD(D is the steam flowmeter inside
Length of straight pipe;For easy installation and disassembly, the pipe expander can be modified after the steam flowmeter.
The direction of fluidity in fluid mechanics is consistent with the direction of arrow sign of steam flowmeter.
The inner lining of the steam flowmeter should be damaged by vacuum pump in the pipeline.
There should be no magnetic field around the steam flowmeter;There should be sufficient indoor space around the steam flowmeter to facilitate installation and maintenance.
If the measuring pipe has vibration, the two sides of the steam flowmeter should be fixed fixed rubber support;
When measuring the mixing liquid of different substances, the distance between the mixing point and the steam flowmeter should be less than 30×D(D is the inner diameter of the steam flowmeter);
Shanghai cixi instrument co., LTD. Is a family enterprise, engaged in the development and production of high-precision flowmeter, which can be applied to almost any pump.Our factory in order to ensure the after-sales and price, cancel the intermediary agent, and end customers and market to maintain close contact, the quality of the flowmeter has reached the world's first-class level.
