Common Parameters

Flow Range: Typically expressed in units such as standard cubic meters per hour (Nm³/h) or standard cubic feet per minute (SCFM), this range defines the versatility and adaptability of the flow meter. For example, a well-engineered flow range might extend from as low as 0.1 Nm³/h to as high as 100 Nm³/h, ensuring it meets the diverse demands of specific models and varied applications.
Accuracy: Expressed as a percentage of the measured value, accuracy is crucial for reliable performance. Our flow meters typically feature an accuracy range of ±1% to ±3%, providing confidence in precise and dependable measurement outcomes for your critical applications.
Repeatability: This parameter showcases the flow meter's ability to deliver consistent results under unchanged conditions. An excellent Thermal Mass Gas Flow Meter will typically offer a repeatability of ±0.5% or superior, ensuring reliability in repeated measurements.
Operating Temperature Range: To ensure optimal performance, the flow meter operates efficiently within a specified temperature range. For instance, it can seamlessly function from -20°C to 200°C, making it suitable for a wide array of environmental conditions.
Output Signal: Standard output signals include the widely adopted 4 - 20 mA current signal, essential for transmitting measured flow data to control systems or monitoring devices. Additionally, select models offer digital outputs like the Modbus communication protocol, enhancing data transfer and integration capabilities for comprehensive system connectivity.
