Working Principle:
There are two temperature transducers: one continuously measures th medium temperature (T1), while the other is self-heated to a temperature (T2) higher than the medium. The temperature difference ΔT = T2− T1. When fluid flow through, it carries away heat from T2. To maintain ΔT constant, the supply current to T2 must be increased. The faster the flow velocity, the more heat is removed, and there exists a fixed functional relationship between the gas flow rate and the additional heat input − this is the principle of constant temperature difference. The relationship between flow velocity and gas density is also deterministic, allowing the direct calculation of gas mass flow rate.
Key Benefits:
No moving parts, minimal wear;
Resistant to pipeline vibration;
Compact structure, easy installation & maintenance;
Long service life;
In-line installation & maintenance (customized solution).
