THE METER OF CHOICE
Since the late 1970’s, the Vortex direct steam flow meters have been acknowledged as the industry standard for direct steam flow measurement.
THE METER OF CHOICE FOR HIGH PRESSURE SATURATED AND SUPERHEATED STEAM
The Cadillac ® Piezo Electric Vortex meter is a rate, totalizing and Mass flow meter which is capable of measuring liquid, steam and gas. Due to it’s piezoelectric sensor technology it is particularly suitable for direct high pressure saturated and superheated steam measurement. In any high pressure saturated or superheated steam application, the Cadillac® Vortex meter is the number one technology choice due to Cadillac’s® accuracy, linearity, reliability and rangeability.
Like many other flow meters, the Cadillac Vortex meter is a velocity measuring device which computes flow by multiplying the effective cross sectional area of
the flow meter with the detected fluid velocity. The meter has no moving parts and consists of a rugged vortex strut with embedded piezoelectric crystals and an amplifier assembly. It detects velocity by measuring the frequency of the vortices, as the peel off the vortex strut of the flow meter. The frequency of these “Karman” vortices is directly proportional to the velocity of the moving fluid, whether this is a gas or liquid.
MASS FLOW COMPENSATION FOR SUPERHEATED STEAM
For compressible fluids, such as superheated steam, an external pressure input (4-20 mADC) into the meter electronics is required to provide mass flow computation. Central Station Steam Company also offers a complete line of Pressure elements.
