Common Parameters

Flow Range: Typically measured in units like standard cubic meters per hour (Nm³/h) or standard cubic feet per minute (SCFM), the flow range of our sensor is versatile, often spanning from 0.1 Nm³/h to a substantial 100 Nm³/h. This adaptability ensures it meets diverse model specifications and application needs.
Accuracy: Our sensor guarantees a high precision level, with accuracy typically maintained within a narrow margin of ±1% to ±3% of the reading. This precision assures you of reliable and consistently accurate measurement results in your operations.
Repeatability: The hallmark of a superior flow meter is its consistent performance. Our Thermal Mass Gas Flow Meter excels with a repeatability of ±0.5% or better, ensuring you receive reliable measurement results time after time under identical conditions.
Operating Temperature Range: Engineered for flexibility, our flow meter operates efficiently across a broad temperature range, from -20°C to 200°C. This capability allows it to function seamlessly in varied environmental settings.
Output Signal: Our devices offer robust output signals, including the widely-utilized 4 - 20 mA current signal, ideal for transmitting flow data to control systems. For advanced data handling, some models feature digital outputs like the Modbus communication protocol, enhancing data transfer capabilities.
