Model Integration with energy management systems A Meter-bus interface enables the Heat Calculator to be incorporated into energy management systems complying with European IEC protocol standards. The is also supplied with an RS bus, which uses industry standard Modbus RTU protocol, for interfacing to computers and DCS www.doorway.rug: manual. Contrec BTU Meter measures the temperature in the supply and return flow lines and uses this information to calculate the enthalpy and density of water. The Model measures the temperature in the feed and return flow lines and uses this information to calculate the density and enthalpy of water. By also measuring the volume of water flowing in the system, the Model will then determine the energy used. Power is calculated as: P = V x ᵨx (hTV - hTR) where P = Power (W).
