Common Parameters

Flow Range: Typically described in units like standard cubic meters per hour (Nm³/h) or standard cubic feet per minute (SCFM), this parameter is crucial for determining the operational scope of the flow meter. For instance, a standard flow range could span from 0.1 Nm³/h to 100 Nm³/h, tailored to suit various model specifications and application needs.
Accuracy: This is a critical metric, expressed as a percentage of the measured value, reflecting the precision of the flow meter. Generally, accuracy levels range within ±1% to ±3% of the reading, guaranteeing dependable and precise measurement outcomes.
Repeatability: Denoting the flow meter's capability to consistently reproduce the same measurement results under identical conditions, repeatability is a hallmark of quality. A superior Thermal Mass Gas Flow Meter often boasts a repeatability of ±0.5% or even better.
Operating Temperature Range: The capacity of a flow meter to function effectively across various temperatures is vital. Typically, this range might extend from -20°C to 200°C, facilitating its use across diverse environmental conditions without compromising performance.
Output Signal: Widely adopted output signals include the 4 - 20 mA current signal, essential for transmitting measured flow data to control systems or other monitoring devices. Additionally, some models offer advanced digital outputs, like the Modbus communication protocol, for enhanced data transfer and system integration.
