Cadillac - Model CG -Gravity Condensate Meter
The Cadillac CG Gravity Condensate Meter is a totalizing meter which measures liquid or condensate in a full or partially filled gravity flow piping system. In any steam system where condensate is available, the CG Gravity Condensate Meter is the number one choice due to Cadillac’s accuracy, reliability and infinite rangeability in gravity flow systems.
The underlying principle of the CG Gravity Condensate Meter is: one pound of steam equals one pound of water. Based on this principle, the condensate volume measurement can be converted into a measurement of steam consumption. Cadillac® does this by measuring the volume of condensate while adjusting for the density. This produces a reading in pounds.
Steam is measured either as a commodity to be bought, sold, or to determine the efficiency of a given system. Therefore, the efficiency and reliability of the metering equipment cannot be over-emphasized. No other meter has the capability to measure full rated capacity or a drop at a time, while maintaining an accuracy of +/- 1% of consumption. This is important because steam loads vary widely with seasons and time of day. The CG Gravity Condensate Meter can handle all load and flow variations and are unaffected by any pressure fluctuations in the steam system.
The Cadillac® CG Gravity Condensate Meter is a totalizing meter which measures liquid or condensate. This meter can be applied effectively for the following purposes:
- 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.
In any steam system where condensate is available, the CG Gravity condensate meter is the number one choice due to Cadillac®’s accuracy, rangeability, longevity, and modern electronics.
- Accuracy: +/-1% of the reading Capable of measuring full-rated capacity or a drop at a time while maintaining an accuracy of +/- 1% of the flow rate.
- Rangeability: From 0 to full-rated capacity with seasonal steam load variation, the need for a large turndown is essential. Cadillac® Condensate Meters are the only meters that will accurately measure down to virtually no flow.
- Longevity: 100 Years and still going strong Meters in service for over 50 years are common. With proper maintenance Cadillac® Condensate Meters will provide reliable, accurate service for many years.
- Modern Electronics: Meeting the challenges of the next millennium Meters are equipped with electronics capable of registering locally, remotely or interfacing with energy.
Cadillac® CG Condensate Meter – Operation Principles
Cadillac® CG Gravity condensate meter operates in the following way. The metering drum consists of 6 scroll shaped compartments. Liquid enters the meter through an axially mounted inlet spout at the center of the drum. As each compartment fills, the excess overflows into the next. This action shifts the center of gravity causing the drum to rotate. The number of filled compartments can be directly converted into steam consumption.
