The Cadillac ® Ultrasonic Vortex meter is a rate, totalizing and Mass flow meter which is capable of measuring liquid, steam and gas. Due to it’s ultrasonic sensor technology it is particularly suitable for direct low pressure saturated steam and gas measurement. In most any gas or saturated 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 small vortex strut, embedded transmitting and receiving ultrasonic transducers, and 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 GASES AND SUPERHEATED STEAM

For compressible fluids, such as gases, an external pressure input (4-20 mADC) into the meter electronics is required to provide mass flow computation. Mass flow computation is available for all gases except Helium and Hydrogen. Central Station Steam Company also offers a complete line of Pressure elements.
