Based on the thermodynamic principle, VTFN300 features 2 temperature sensors inside the probe: onefor medium temperature, the other one is heated a few degrees up compared to the medium into which it projects.When the medium flows, the heat generated in the sensor is conducted by the medium. The difference between these two sensors can be measured to get the flow rate. Compared to traditional products, FN3000 offers a wider measuring range, less temperature drifting, and percentage or flow velocity display. All metal housing.highlighted digital LED, dual-key and user-friendly interface, and multiple process connections.330° rotatable indicator.
