Cadillac® Vortex CV-HS Meter – General Specifications & Sizing
Cadillac® Vortex CV-HS Meter includes the following specifications:
- Meter will consist of a full-bore body, vortex shedding bar and remote or integral electronics.
- Meter available with local or remote indication or blind housings.
- Meter available with pulse and analog (4-20 mA) outputs.
- Instantaneous and totalized flow available at local indicator or remotely through outputs.
- Meter measures flow using the Karman vortex shedding principle.

- Meter electronics shall be capable of direct MASS flow computation for saturated steam without external inputs.
- Meter provides one button auto tuning for setting noise immunity circuits.
- Operating pressure/temperature of meter shall be (Vacuum to 2100 psig)/( -40°F to 500°F)
- Meter will have typical turndown of 15:1, or up to 30:1 if sized for "Best Fit".
- Meter will be calibrated to/and be provided with NIST calibration certificate.
Cadillac® Vortex CV-HS Meter – Sizing Information
The low-end performance of the meter is a function of the fluid’s ability to generate a vortex, which using ultrasonic technology is at the very threshold of when vortices for a given fluid are shed. This threshold is dependent on fluid velocity, density and Reynolds number. The high end of the flow meter is amplitude limited, which ultimately impacts the electronics ability to distinguish one vortex from another. In most cases, this represents 250 ft. /sec for gases and 33 ft. /sec for liquids.
To guarantee satisfactory performance, we will check every vortex meter application for suitability and will require process medium, pressure, temperature and expected minimum and maximum flow rates. For easy reference, we are providing you with a table (see below) for saturated steam at various pressures. The tables list the minimum and maximum flow capability, between which a flow measurement can be made at stated accuracy. Outside those limits, the accuracy will deteriorate somewhat, the extent of which will depend on the quality of the installation.
