How should this flow meter be selected?
Thread Content
How to choose this flow meter: 1. Gas composed of 95% CO2, with N2, O2, etc. accounting for 5%； 2. Pipe diameter of 100 mm, pressure (gauge pressure of 0.8 Mpa), temperature of 25 degrees ； 3. For settlement purposes, there are cumulative and instantaneous readings; the question is whether the flow meter reading represents the volume flow rate under standard conditions (Nm³/h) or the volume flow rate under actual operating conditions (m³/h at a gauge pressure of 0.8 Mpa) ； 4. What is the impact on the flow meter reading when the gas composition changes, for example, when CO2 accounts for 92%? 5. Which flow meter model is better to choose? Higher precision? Or rather, it offers good value for money. Thank you for your answer!
Thermal flow meter; FCI can be selected
Turbine and commercial-grade ultrasonic flowmeters, equipped with pressure stabilization compensation

Thank you all, but there are still some questions unanswered: if a volume flow meter is used, is the volume flow rate indicated under standard conditions or under actual operating conditions? The reading from a mass flow meter is in kg/h, which I know. Mass flow meters are expensive – is it really necessary?
Whether to choose a mass flow meter depends on the consumption volume and price. Generally, if the annual consumption exceeds 1 million yuan, it is recommended to use a mass flow meter; the CMF series from HighAccurate can meet your needs. For a diameter of 80, the cost is around 150,000 yuan. If the annual consumption is not high, it is advisable to use a vortex flow meter; Emerson’s 8800 series can satisfy your requirements. Vortex flow meters directly measure the flow rate under the current operating conditions; pressure stabilization compensation is required to convert this value into a value corresponding to standard conditions
1. The quality of domestic products is no longer that good either. 2. If trade is about profitability, then even with imported products of higher quality, what’s the point of making such an investment? 3. You need to provide detailed specifications, such as the flow rate range, pressure loss limits, and whether the medium contains water or is contaminated by dust
High-precision Roots flow meters are the choice for natural gas metering in many places.
