Flow Meters & Controllers
BHL
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.
Features
* 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)
