Gas turbine flow meter
Application Feature
- natural gas
- LPG City gas
- propane, butane
- air, nitrogen
- industrial inert gas
Feature
- It adopts imported precision bearings specially designed for instruments, which have good durability, stability and lubricity.
- The carefully designed flow channel structure improves the medium adaptability of the flow meter.
- The unique reverse thrust structure and sealing structure design ensure long-term reliable operation of the bearing.
- The flow meter head can be rotated 180°, making installation and use simple and convenient.
- The standard rectifier has excellent rectification performance and requires very low front and rear straight pipe sections.
- Adopting micro-power consumption technology, the temperature and pressure compensation type comes standard with a built-in battery and can work with both internal and external power supplies.
