Favoured by control and instrumentation engineers, Contrec Heat Calculators provide a simple solution to measure the energy consumed in both heating and cooling (air conditioning systems) in hospitals, residential apartment blocks, commercial and industrial buildings to name a few.
The Contrec BTU meters/heat calculators take in flow reading from most types of flowmeters, together with temperature measurements from supply and return lines to accurately calculate the volume flow, energy, power, mass and temperatures of the fluid being measured.
Contrec heat calculators are designed to operate in accordance with international metrology standards on accuracy. Working with either pulse or analogue generating flowmeters such as ultrasonic, electromagnetic or traditional mechanical meters, we then input a temperature measurement from both the flow (prior to the consuming unit) and return (after the consumer) lines into the Contrec BTU instruments. From these three measurements we can accurately calculate the volume flow, energy, power, mass and temperatures of the fluid being measured.
For some applications, specialist fluids are used in heating/cooling systems as they possess improved thermal properties, for example Glycol as an anti-freeze component, or Therminol® heat transfer fluid for efficiency. Contrec BTU energy calculators can allow for these custom fluid properties to provide precise measurement specific to the process.
Contrec Heat Calculator Models
Contrec offer several different models available depending upon the application. Our Model 212 heat calculator looks the part whether installed in a residential complex or in a boiler house with it’s ergonomically designed weatherproof enclosure.
The 515 series BTU models feature many technical advancements including Modbus and Ethernet outputs, and can connect to Contrec’s DataMod software tool which can collate energy data from multiple instruments and provide detailed reports and export data to 3rd party business management systems.
For over 25 years Contrec’s 212 Heat Calculator has been proven in thousands of energy monitoring applications in heating and cooling systems worldwide.
