Advantages of Mass Flow Over Volumetric Flow Measurements
- Mass Flow meter is having widest Turndown Ratio, Fast Response Time, High Accuracy and also High Repeatability
- Mass Flow Rate independence to pressure and temperature changes
- Pressure and Temperature Compensation does not require direct Mass Flow Measurements hence improve the cost-effectiveness of gas flow measurement
VA-Flow Meter v.s. Mass Flow Meter
Industrial flow measurements applications often require a higher accuracy together with pressure and temperature compensation which not possible to achieved with conventional Variable Area Flow Meters.
Hence Variable Area Flow Meters are extremely sensitive to pressure and temperature changes. 1 Bar pressure changes in process can generate an error of 50% in gas flow measurements. Therefore the flow compensation of Mass Flow Meters creates repeatability.
Common Variable Area Flow Meter in flow measurement possible only with Vertical Installation, however, smart Digital Mass Flow Meters provide installations flexibility both horizontally and vertically. In the past the Variable Area Flow Meters having great advantages of no power supply required, however with innovation, now Mass Flow Meter with AA Battery Powered available without compromise of measurement accuracy.
