Plug-in electromagnetic flowmeter installation requirements

Installation requirements and precautions for plug-in electromagnetic flowmeter

Accurate measurement needs to choose the correct instrument, the quality of the instrument is the main, and secondly, it is necessary to consider the installation requirements. If the installation is not standardized, the instrument cannot be fully utilized. Therefore, we must pay attention to the installation of the flowmeter. Yibi company's technical staff to introduce you to the installation requirements and precautions of the plug-in electromagnetic flowmeter:

1. Plug-in electromagnetic flowmeter should be kept away from equipment with strong electromagnetic field;

2 , the installation site should not have strong vibration, the pipeline is fixed firmly, and the ambient temperature does not change much;

3 , the installation position must ensure that the pipe is always filled with the measured fluid, the length of the straight pipe on the upstream side of the sensor installation pipe is greater than 8D, and the length of the straight pipe on the downstream side is not less than 5D;

4. Clean the welding slag and burrs of the base of the pipe to be tested;

5. Install the DN80 ball valve on the mounting base, pay attention to the long cavity of the ball valve up, check that the ball valve switch is normal; install the compression screw seat kit to the ball valve, loosen the positioning screw and the compression nut, insert the sensor into the rod and insert through the ball valve. The pipe being tested. The insertion depth of the sensor is 3mm outside the base. After meeting the requirements, tighten the positioning screw and the compression nut. Also note that the sensor direction mark is consistent with the fluid flow direction.

6. The opening on the pipe to be tested is larger than the base pipe, and the depth of the base pipe inserted into the opening of the pipe to be tested is the flatness of the two sides;

7. The plug-in electromagnetic flowmeter is welded by stainless steel welding rod, and the flange surface is parallel to the tube axis after welding;

8. Connect the power supply and other connections according to the instructions of the plug-in electromagnetic flowmeter. After power-on, check the instrument display to confirm that the pipe under test is full of fluid and the flow rate is zero. ;

9. After the fluid in the pipe under test is flowing and stable, check the instrument display. At this time, turn the sensor direction to maximize the displayed value, and lock the positioning screw and the compression nut;

10. For the case where the flow variation range is large and the fluid velocity is lower than the minimum flow rate required by the flowmeter for a long time, it should be considered to reduce the process pipeline or use two large and small small parallel flowmeters;

11. The plug-in electromagnetic flowmeter should be installed on the vertical process pipe as well as the ordinary electromagnetic flowmeter. This prevents the suspended solid from sinking on the electrode and raises the oil in the fluid outside the measurement range of the electrode. When the flowmeter is installed on the horizontal process pipeline, the electrode of the sensor should be placed on the horizontal axis to avoid the interference of the electrode due to the bubble, resulting in measurement error;

12 , vertical installation, the sensor should be inserted into the pipeline should be less than 5 ° angle with the vertical diameter of the pipeline section, suitable for measuring the cleaning medium with small vibration of the pipeline;

13. Tilt-mounted, the axis of the sensor is 45° from the axis of the pipe to be tested. It is suitable for large-diameter and measuring the flow of liquid containing other impurities in the medium. The installation method has small water resistance and should not be entangled.

The background and signification of research this program

As plastic has been used for all other industry widely, they are playing an important role in the development of our economy, but plastic did not easy to broken after being used and it becomes a big pollution for our environment .Therefore it is urgent to process those waste material without pollution.

In addition ,as the fastest development of world economy ,the shortage of petroleum will be urgent more and more .even the expert had stated that it will have no petroleum recover in earth after 15 years later, so searching the new resource becomes an issue which is concerned by all the countries of the world.  

so it have great meaning of settle this program ,which can recycled waste material like plastic into resources without any pollution.

1.Working process Of waste plastic Pyrolysis Plant:

First, the raw materials are put into the reactor, and then seal the feeding in door, later start the machine and the reactor will be rotating and heated by coal, natural gas, wood or electricity. When the temperature reaches the degree of 250 to 280, we will get the crude oil, the oil steam will be continuous produced until the temperature reaches 350-460 C; oil steam will flow through oil gas separator, light component will enter the condensers and meanwhile the heavy oil will be discharged automatically into in heavy oil tank. The liquefied part will be condensed as crude oil, and the part which cannot be liquefied will be transferred by the water seal back to the burning chamber to be reused as heating material.

2. Model of waste plastic Pyrolysis plant:

3. Plastic Oil output reference: 20%~75%

4. Installation: We will be in charge of arranging our engineer to go to your place to guide the installation and train your workers how to operate the waste plastic pyrolysis plant,and buyer will be in charge of the food, accommodation and round air tickets. 

 5. Land requirement: 300sq meters(10m*30m)

 6. Exporting Experience:
