Cadillac HEATX - BTU Energy Meter
The Cadillac BTU Meter (HEATX) is designed to measure the energy consumed in hot water heating and chilled water cooling systems. The system is a rate and totalizing device, which is capable of calculating and displaying Volume, Energy, Temperatures and Peak Energy usage. Combined with Cadillac®’s superior flow meter technologies the HEATX provides the most accurate, repeatable, and maintenance free energy system available in the industry.
The Cadillac® BTU Meter (HEATX) measures the temperature in the feed and return lines via two precision matched 4-wire RTD’s and from this calculates the density and enthalpy of the water. In addition, by also measuring the volume of water flowing in the system via the Cadillac® flow meter, the HEATX will then compute, display, and output the Energy consumed.
The New Industry Standard
Combined with Cadillac®’s superior flow meter technologies the HEATX BTU meter has quickly become acknowledged as the industry standard. Customers choose the Cadillac® HEATX BTU Meter because of proven: accuracy, dependability, consistency, maintenance, reliability and rangeability.
Cadillac® BTU / Energy Meter has the ability to provide the best suited and widest range of application solutions to meet the end users energy measurement needs.
The Cadillac® HEATX BTU / Energy Meter is the meter of choice for energy applications. This BTU meter can be applied effectively for the following purposes:
- Energy consumption data source for energy management system, DCS, district-wide systems.
- Energy-Customer Billing from accurately totalized Energy / BTU meter measurements.
- Basis for internal cost distribution using campus-wide systems.
- Efficiency measuring and monitoring from central control rooms.
- Direct Energy / BTU meter measurements at both Boiler and point of use locations.
The Cadillac® HEATX BTU Meter is the meter of choice for energy applications. This meter contains the following features:
- Heating Mode: Where Positive ΔT’s only are totalized.
- Cooling Mode: Where Negative ΔT’s only are totalized.
- Heating/Cooling Mode: Where the flow of energy may be for either heating or cooling. In this mode the energy total is increased regardless of whether the ΔT is positive or negative.
- Charge/Discharge Mode: Where two separate registers totalize positive and negative totals.
The Cadillac® HEATX BTU Meter measures the temperature in the feed and return lines via two precision matched 4-wire RTD’s and from this calculates the density and enthalpy of the water. In addition, by also measuring the volume of water flowing in the system via the Cadillac® flow meter, the HEATX BTU meter will then compute, display, and output the Energy consumed.
Power is Calculated:
- P = V x p x (htv-htr)
Where:
- P = Power (watts)
- V = Volumetric flow Rate
- p = Density
- htv = Specific enthalpy at Feed temperature
- htr = Specific enthalpy at Return temperature
