Type Ellipse® belongs to the Pitot tubes family, which measuring principle is working on the basics of the Bernoulli equation. In contrast to the venturi tube, work is done with the help of a second tube which is oriented parallel to the flow of the medium, such that the flow impinging on a front pipe opening. In front of the tube is formed the dynamic pressure, behind the tube, the static pressure. This remains constant.
The type Ellipse® covers the whole range of differential pressure flow measurement. The patented elliptical design outperforms and provides great turndown ratio 17:1. The model measures liquids, gases or steam in pipe sizes from DN 50 to DN 3050 (2" to 120") with an accuracy of ± 0.75% of reading.
By different shaped pipe openings, measurement results can be affected. By the elliptical shape of the shaft, lowest permanent pressure loss is achieved.
Type Ellipse® can be used both vertically and horizontally.
