Common Parameters

Flow Range: Usually specified in units such as standard cubic meters per hour (Nm³/h) or standard cubic feet per minute (SCFM). For example, a typical flow range could be from 0.1 Nm³/h to 100 Nm³/h, depending on the specific model and application requirements.
Accuracy: Expressed as a percentage of the measured value. Commonly, the accuracy can be within ±1% to ±3% of the reading, which ensures reliable and precise measurement results.
Repeatability: This indicates the ability of the flow meter to reproduce the same measurement results under the same conditions. A good Thermal Mass Gas Flow Meter may have a repeatability of ±0.5% or better.
Operating Temperature Range: The flow meter should be able to operate within a certain temperature range. For instance, it could range from - 20°C to 200°C, allowing it to be used in different environmental conditions.
Output Signal: Common output signals include 4 - 20 mA current signal, which is widely used for transmitting the measured flow data to control systems or other monitoring devices. Some models may also offer digital outputs such as Modbus communication protocol for more advanced data transfer and integration.
