Product Features
1. The throttling device has a simple and sturdy structure, stable and reliable performance, long service life, and low price.
2. Wide application range, all single-phase flows can be measured, and some mixed phase flows can also be applied, especially for measuring high-temperature and high-pressure media.
3. Standard throttling devices do not require real flow calibration and can be put into use.
4. The integrated orifice plate is easy to install and does not require pressure pipes. It can be directly connected to differential pressure transmitters and pressure transmitters.
5. The scope of application is applicable to the measurement of fluids containing dirt, air bubbles, or solid particles.
