Elliptical flow meter

With a patented elliptical design and aerodynamic characteristics, the Preso Ellipse flow meter overcomes loss of accuracy caused by fluid separation at the sensor body. A series of ports face upstream velocity pressures while flow-sensing ports are located ahead of the trailing edge flow separation to measure the actual differential pressure signal within +/-0.75% accuracy and +/-0.1% repeatability.
