TMF热式气体质量流量计是气体流量计中的新型仪表，区别与其他气体流量计，不需要进行压力和温度修正，直接测量气体中的质量流量。可以做到量程极低到高量程，量程比高，测量精准。
应用领域：
• 水及污水处理：曝气空气流量等
-
- No need for pressure or temperature compensation, directly measures gas mass flow.
- High turndown ratio (greater than 100:1).
- A single flow meter can handle both low and high flow rates, making it particularly suitable for large-diameter measurements.
- Excellent for leak detection in process pipelines and equipment.
- Minimal installation effort: Due to its insertion-type design, only an M20x1.5 hole needs to be drilled in the pipeline.
- Equipped with a ball shut-off valve for easy calibration and maintenance.
- Compatible with intelligent digital flow totalizers.
- Features on-site operation, automatic data storage during power outages, preset system data, and fault feedback.
- Fast response and high accuracy.
- Field-mounted instruments can display data locally and include alarm control functions.
- High sensitivity, especially suitable for large-diameter pipelines and low-velocity flow measurements.
