The LCSH dual-throat velocity measurement device is a type of differential pressure flow detection instrument. When used with a differential pressure transmitter, it can measure gases, liquids, and steam in industrial applications. It has advantages such as simple structure, convenient installation and maintenance, low permanent pressure loss, and stable long-term operation.
Features
- 1) Low pressure loss, only 3% of orifice plate pressure loss, greatly improving system economy;
- 2) Stable signal;
- 3) Within 2×10⁴ < ReD < 2×10⁶, flow coefficient K is independent of Reynolds number changes;
- 4) Rectifies and sucks inlet flow field, allowing small inlet flow to produce large differential pressure;
- 5) High measurement accuracy: up to ±2.5%;
- 6) Wide turndown ratio: up to 10:1, suitable for single-phase gas and steam measurement.
