Equipment Configuration:natural gas magnetic inductive flowmeter

Flow is an important detection parameter of natural gas purification device, the correct fluid flow measurement is to ensure the safe operation of the production process, improve product quality basis. With the progress of science and technology, in order to ensure the quality of natural gas purification, energy saving and emission reduction, improve production efficiency, people in the improvement of the performance of the flow meter, the use of the object adaptability to enhance the economy to improve the various aspects of the corresponding methods and measures. Natural gas purification device fluid medium is complex and diverse, the measurement environment is not the same, there are a variety of flowmeter types to choose from, the commonly used flowmeter is mainly orifice plate flowmeter, vortex flowmeter, electromagnetic flowmeter, ultrasonic flowmeter and so on.

Project Overview

Supmea Automation Co.,Ltd analyzes the natural gas magnetic inductive flowmeter selection method from five aspects: instrument performance, fluid characteristics, installation conditions, environmental conditions and economic factors. The considerations for each aspect are as follows:

  • 1. Instrument performance: accuracy, repeatability, linearity, range, pressure loss, upper and lower flow limits, signal output characteristics, response time and so on.
  • 2. Fluid properties: fluid pressure, temperature, density, viscosity, lubricity, chemical properties, wear and tear, corrosion, scaling, dirt, gas compression coefficient, isentropic index, specific heat capacity, conductivity, speed of sound, mixed-phase flow, pulsating flow and so on.
  • 3. Installation conditions: pipeline layout direction, flow direction, upstream and downstream pipeline length, pipeline caliber, maintenance space, pipeline vibration, grounding, power supply, auxiliary equipment (filtration, sewage), explosion-proof and so on.
  • 4. Environmental conditions: ambient temperature, humidity, security, electromagnetic interference, etc.
  • 5. Economic factors: acquisition costs, installation costs, maintenance costs, calibration costs, service life, operating costs (energy consumption), spare parts and so on.

Based on the five aspects of the initial selection of available instrument types, using the elimination method in the comparison of 2-3 types, ranking, and again according to the five aspects of the careful evaluation, eliminated to a type of instrument type.

The success of the selection depends largely on the selection of the quality of the instrument performance and the exact understanding of the characteristics of the measurement object. For the instrument performance quality should pay special attention to manufacturers of false advertising and misleading components. Measurement of the exact understanding of the object is very important, not the user's own measurement of the object have an accurate understanding of many selection failure is due to the provision of inaccurate parameters. Some of the characteristics of the object is the need for in-depth investigation to figure out.
