The Ellipse Model BHL annular hot tap, dual rod flow device is a multi-ported, self-averaging differential pressure flow element. Its innovative elliptical shape provides the lowest permanent pressure loss in the industry. The Ellipse flow meter is designed with a series of ports facing the upstream velocity pressures and flow sensing ports strategically located ahead of the trailing edge flow separation.
- No separation effects on the low (static) pressure
- Turndown ratio of 17:1
- No vacuum effects
- No vortex generation
- Very high repeatability
- Lowest drag coefficient (lowest pressure loss in the industry)
