1. What parameters can a compressed air flow meter monitor?
A compressed air flow meter can monitor the following core parameters.
1. Basic flow parameters • Instantaneous flow: Real time monitoring of the flow rate of compressed air in the pipeline (unit: m ³/min or Nm ³/h) • Cumulative flow: Record the total amount of gas passing through the pipeline during a specific time period (unit: m ³ or Nm ³) • Mass flow: Some models can directly measure gas mass (unit: kg/h) 2. Operating condition parameters • Pressure value: Synchronized detection of gas pressure in the pipeline (usually 0-1.6 MPa) • Temperature value: Real time monitoring of gas temperature (typical range: -20 ℃~+80 ℃) • Dew point temperature: High end models can output compressed air humidity Parameter 3 Energy efficiency parameters • Flow rate: displays the gas flow velocity inside the pipeline (unit: m/s) • Compression ratio: calculated from pressure data • Leakage rate: detects system leakage through flow mutation analysis Advanced functional parameters (specific model support required) • Density compensation: automatically corrects flow data affected by temperature and pressure • Energy consumption: calculates energy consumption of compressed air system (kW · h/m ³) • Pulse output: converts flow signal into standard pulse signal (such as 4-20mA) • Note: The specific monitoring and measurement force depends on the equipment model, and thermal flow meters usually have more temperature monitoring functions than mechanical flow meters. In 2023, data from the Ministry of Industry and Information Technology showed that the detection error rate of mainstream model parameters was ≤ 1.5%.
