Key Features & Advantages

Solid-State Thermal Dispersion

Thermal-dispersion sensing has no moving parts or pressure sensor, supporting stable measurement with low maintenance.

0.5-100 Nm/s Gas Velocity Range

Covers gas velocities from 0.5 to 100 Nm/s, supporting low-flow detection and wider process monitoring.

Digital Accuracy and Vibration Resistance

Internal digital measurement improves accuracy and stability, while the solid-state sensor resists vibration for longer service life.

Optional Non-Stop Installation and Service

Compact construction simplifies installation and maintenance; special customization can permit servicing without stopping production where site conditions allow.
