Common Parameters

Flow Range: Expressed in units like standard cubic meters per hour (Nm³/h) or standard cubic feet per minute (SCFM). A versatile range might span from 0.1 Nm³/h to 100 Nm³/h, crafted to align with specific model requirements and application demands, ensuring maximum adaptability.
Accuracy: Represented as a percentage of the measured value, accuracy typically ranges within ±1% to ±3%, guaranteeing reliable and precise measurement results, crucial for consistent performance.
Repeatability: This defines the flow meter's ability to consistently replicate identical measurement results under stable conditions. A premium Thermal Mass Gas Flow Meter often features a repeatability of ±0.5% or better, underscoring its reliability.
Operating Temperature Range: Essential for optimal functionality, the flow meter must perform efficiently within a specified temperature range. For example, it may operate seamlessly from -20°C to 200°C, ensuring versatility across various environmental conditions.
Output Signal: Standard output signals include the 4 - 20 mA current signal, widely used for transmitting measured flow data to control systems or other monitoring devices. Select models may also offer digital outputs like Modbus communication protocol for enhanced data transfer and integration capabilities.
