Installation method of liquid flowmeter

The total flow and temperature, working pressure, level gauge, is the general heat insulation chemical plant processing process of the key main parameters, we use this main parameters to monitor and control the production process, and maintain the automation of the production process technology.This has a key practical significance in improving the quality and production of commodities, ensuring safe production, improving practical processing technology, improving manufacturing standards and scientific tests.About steam flowmeter installation is to have an attention.

Installation method of liquid flowmeter

1. Looper flange, bolt connection and clamping are generally used for the installation of liquid vapor flowmeter;

 

2. During installation, the direction of liquid flow should be in the same direction as the arrow symbol marked on the sensor housing, and the upstream and downstream straight pipe segments should be ≥20dn, and the middle and downstream straight pipe segments should be ≥5dn, in which dn is the nominal diameter of the pipeline.

 

3. The sensor shall eliminate the external electromagnetic field. If it cannot be prevented, necessary countermeasures shall be adopted;

 

4. In order to ensure that all normal liquid transportation is not harmed during maintenance, bypass valve pipelines should be installed outside the straight pipe sections on both sides of the sensor;

 

5, sensor outdoor installation, please do a good job of amplifying instrument plug moisture-proof solution;

 

6. The sensor of liquid vapor flowmeter can be installed horizontally and vertically, and the direction of fluid mechanics must be upward when vertical.Liquid should fill the pipeline, no bubble.During installation, the direction of liquid flow shall be the same as the arrow sign on the sensor housing indicating the inflow.The upper and lower end of the sensor shall have at least 20 times the nominal pressure nominal diameter of the straight tube segment, and the middle and lower end shall have more than 5 times the nominal pressure nominal diameter of the straight tube segment. The inner cavity shall be clean and clean without pits, scaling and peeling.

 

7. In case of unsteady fluid mechanics and pulsation flow, a buffer can be installed to clear the pulsation flow to ensure the excellent and accurate measurement of the rotor flowmeter.In the application of the rotor flowmeter, it is necessary to slowly unscrew the control gate valve on the upstream and downstream pipeline of the steam flowmeter, and then adjust the total flow with the regulating valve to prevent the sudden opening of the oil level sensor and the rapid rise of the cone.

 

Flowmeter meter is an important part of the company's economic accounting. Accurate reliability of flowmeter meter is the precondition to ensure the company's normal production and manufacturing, and it is one of the key ways to maintain economic benefits.

 

With the development of the society, all walks of life pay more and more attention to the automation process control. Seeing the turning point of the instrument industry, MrStone resolutely resigned as a senior engineer of Siemens, inherited the family business, and left his hometown to set up Shanghai porcelain xi instrument co., LTD.Specializing in the production and development of high precision, wide range of flowmeters.The output equipment all USES the Siemens numerical control machining center, the cutting precision is up to 0.001mm, the production process strictly implements the ISO9001 standard, lets you in China can also buy the German quality flowmeter.
