Cadillac HS Vortex Meter

The Cadillac® Vortex Meter is a rate and totalizing meter which is capable of measuring liquid, steam and gas. Due to it’s rugged design it is particularly suitable for direct steam measurement. In any steam system 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 meter & bluff body (shedder bar) and amplifier assembly. It detects velocity by measuring the frequency of the vortices, as they peel off the shedder bar of the flowmeter. The frequency of these “Karman” vortices is directly proportional to the velocity of the moving fluid, whether this is a gas or liquid.
APPLICATIONS
Data Source for energy management system, DCS, district-wide systems.
Energy-Customer Billing from accurately totalized flow measurements.
Basis for internal cost distribution using campus-wide systems.
Process monitoring from central control rooms.
Direct Steam measurements at both Boiler and point of use locations.
Natural Gas measurements for Boiler fuel flow.
FEATURES
ACCURACY: +/-1.0% of the reading for liguids, gas, and steam.
RANGEABILITY.: Typically 15 to 1 turndown or better.
With seasonal steam load variation, the need for a large turndown is essential. Cadillac® Vortex Meters will accurately measure all load requirements with proper sizing.
LONGEVITY: Mean time between failure (MTBF) of 50 years.
With no moving parts and through simple robust design the MTBF of the shedder bar is 50 years. With proper system maintenance Cadillac® Vortex Meters will provide reliable,accurate service beyond all flow technologies.
MODERN ELECTRONICS: meeting the challenges of the information highway
Meters are equipped with electronics capable of registering locally, remotely or interfacing with an energy management system. Built to withstand the toughest conditions.
