Common Parameters

Flow Range: A robust flow range, typically defined in standard units such as cubic meters per hour (Nm³/h) or cubic feet per minute (SCFM), ensures versatility across various applications. For example, a dynamic flow range might extend from 0.1 Nm³/h to 100 Nm³/h, skillfully customized to meet the unique requirements of specific models and applications.
Accuracy: This crucial parameter, denoted as a percentage of the measured value, usually falls within ±1% to ±3%, providing reliable and precise measurement results that you can trust.
Repeatability: A hallmark of superior flow meters, this feature indicates the ability to consistently deliver identical measurement results under unchanged conditions. Premium Thermal Mass Gas Flow Meters often offer exceptional repeatability at ±0.5% or better.
Operating Temperature Range: Our flow meters are designed to function optimally within a specified temperature range, such as from -20°C to 200°C, ensuring adaptability to a wide array of environmental conditions.
Output Signal: Standard output signals, like the widely-utilized 4 - 20 mA current signal, facilitate seamless data transmission to control systems or monitoring devices. Moreover, select models may offer advanced digital outputs such as the Modbus communication protocol for enhanced data integration and transfer capabilities.
