Natural Gas Flowmeter Selection - Focus on Microfluidic Control Technology

Faced with so many varieties of natural gas flow meters, the selection of general users has become a problem. How to scientifically and objectively select the best flowmeter is a problem that needs attention. We believe that selection should follow appropriate rules, try to avoid misleading propaganda from manufacturers, and find a flow meter that is right for itself. It is its ideal flow meter.

The selection can be carried out in five aspects: instrument performance, fluid characteristics, installation conditions, environmental conditions and economic factors. The various considerations are as follows:

1. Instrument performance: accuracy, repeatability, linearity, range, pressure loss, upper and lower limit flow, signal output characteristics, response time;
2. Fluid properties: fluid pressure, temperature, density, viscosity, lubricity, chemical properties, wear, corrosion, fouling, dirt, gas compression coefficient, isentropic index, specific heat capacity, conductivity, sonic velocity, miscible flow, pulsating flow, etc. ;
3. Installation conditions: pipeline layout direction, flow direction, upstream and downstream pipeline length, pipe diameter, maintenance space, pipeline vibration, grounding, power supply, auxiliary equipment (filtering, sewage discharge), explosion-proof, etc.;
4. Environmental conditions: ambient temperature, humidity, safety, electromagnetic interference, etc.;
5. Economic factors: purchase fees, installation fees, maintenance fees, calibration fees, service life, operating costs (energy consumption), spare parts, etc.
