Cadillac HEATX - Model 2 -BTU Energy Meter
The NEW Cadillac® HEATX-2 BTU Meter is the first single or dual measurement system, designed to measure the energy consumed in Single or Dual Channel Hot/Chilled water, Condensate (Total Heat BTU), Single pipe Heat/Cool, and Forward/Reverse flow Heating or Cooling systems. The system measures, calculates, displays, and stores energy consumption, which include Volume, Energy, Power, and Temperatures. Key features include a graphical color TFT VGA display, an onboard memory for archiving, a 10/100base T Ethernet port with a wide variety of communication protocols, and a USB connection. Combined with Cadillac ®’s superior flow meter technologies the HEATX provides the most accurate, reliable, and maintenance free energy system available in the industry.
The Cadillac ® HEATX-2 was designed with 50 MB of onboard flash memory for data archiving for redundancy, if connected to a BAS/BMS. Or stand alone for users without a building automation system. Once archived data may be transferred via Ethernet or USB and can be viewed on Energy Review archiving software optional with each HEATX-2 system.
Cadillac® HEATX-2 Energy / BTU Meter – Applications
The Cadillac® HEATX-2 single or dual BTU / Energy Meter is the meter of choice for energy applications. This BTU meter can be applied effectively for the following purposes:
-
Energy / BTU consumption data source for energy management system, DCS, district-wide systems.
-
Energy / BTU Customer Billing from accurately totalized Energy / BTU meter measurements.
-
Basis for internal Energy / BTU 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-2 BTU Meter is the meter of choice for energy applications. This meter may compute any one or combination of two of 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-2 measures the temperature in one or two separate feed and return lines via two precision matched RTD transmitters. This then calculates the weight density and enthalpy of the water. In addition, by measuring the volume of water flowing in two separate lines either via the Cadillac® flow meter or other meter technology that provides an analog (4-20 ma) output, the HEATX-2 system will then compute, display, and output the Energy consumed.
The Cadillac® HEATX-2 BTU Meter measures the temperature in one or two feed and return lines via precision matched 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 one or two Cadillac® flow meters (or any volumetric flow meter with a analog output), the HEATX-2 BTU meter will then compute, display, archive, and output the Energy consumed.
Power is Calculated:
-
P = V x p x (htv-htr)
Where:
-
P = Power (BTU/Hr)
-
V = Volumetric flow Rate (Gal/Hr)
-
p = Density
-
htv = Specific enthalpy at Feed temperature (Btu/Lb)
-
htr = Specific enthalpy at Return temperature (Btu/Lb)
