Gasoline Turbine Air Flow Meter Sensor 304/316L Stainless Steel with Pulse Output DN15-DN300 4-20mA
Professional gasoline turbine air flow meter sensor constructed from premium 304 or 316L stainless steel materials, featuring pulse output for precise flow measurement applications.
The LUGB vortex flowmeter operates on the Karman vortex principle, where a triangular prism generates alternating vortices in the fluid stream. The vortex separation frequency is directly proportional to the flow velocity, enabling accurate calculation of fluid flow rates through sensor detection and signal processing.
- High accuracy with excellent repeatability performance
- Non-contact detection element ensures stable operation and reliability
- Robust construction with minimal moving parts for long-term reliability
- Wide measurement range with 1:10 ratio (up to 1:15 for special applications)
- Low pressure loss - approximately 1/4 to 1/2 of orifice flowmeters
