THE METER OF CHOICE
Since 1906, the Cadillac® Condensate Meter has been acknowledged as the industry standard.
The Cadillac® CG Gravity Condensate Meter is a totalizing meter which measures liquid or condensate. 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.
The underlying principle of the CG Gravity Condensate Meter is: one pound of steam equals one pound of water. Based on this principle, the volume of the condensate 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 and 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. Cadillac® CG Gravity Condensate Meters can handle all such variations and are not effected by any pressure fluctuations in the steam system.
GRAVITY INSTALLATION
A gravity installation is intended for use on heating systems where the steam condensate flowing from the meter by gravity is at or near atmospheric pressure.
The condensate receiver is optional in an installation where the condensate temperature is moderate and steam traps in the system are reliable enough to prevent excessive steam from reaching the meter. Steam trap selection should include consideration of reliability and uniform flows to the meter. Float and thermostatic traps are generally recommended.
Please note: A properly installed F&T trap can actually be located below the meter with moderate steam pressures that will move the condensate up to the meter. This allows the greatest layout flexibility. Refer to trap manufacturer for details.
Use of a receiver is recommended in several cases. System design may require that very hot condensate be handled. A receiver is a convenient way to allow for flashing. The receiver also provides surface area for cooling. Flow surges that briefly exceed the capacity of the meter are also accommodated by the receiver.
Where several meters are required in parallel because of large flows or several streams, a receiver is an excellent solution. Multiple receiver inlets or outlets reduce header requirements. Receivers are generally sized for a nominal hold time of 5 to 10 minutes depending on surge and flash conditions
VACUUM INSTALLATION
Vacuum-rated condensate meters are used for metering on the suction side of a vacuum pump. A thermostatic air valve is recommended as shown.
The vacuum installation is used where condensate is brought back to the power plant through a common return line. In this installation, the master trap isolates the heating system from the vacuum. A reliable, uniform flowing trap such as a float and thermostatic unit is recommended.
If the individual traps are reliable enough to prevent steam leakage into the return line, the master trap may be omitted and the meter installed with an air bypass.
The air bypass should be used whenever air may enter the system. Care in vertical positioning is required to avoid condensate flowing through the air bypass. Vacuum pump controls should permit continuous operation of the vacuum pump in order to ensure drainage of condensate from the meter.
An optional vacuum receiver following the meter also levels out flow conditions.
FEATURES:
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 an energy
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.
PRINCIPLE OF OPERATION
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.
