The diagram shows the standard assembly with the modules (left to right). -
Page 18: Heat Meter Application
9.1.2 Heat meter application When used as a heat meter, the transport of energy from a heat source to the consumer is meas- ured in the supply and return flow of a transport duct. This requires signals measuring the supply temperature and the return temperature, and signals from a flow sensor. -
Page 19: Cooling Meter Application
9.1.3 Cooling meter application The following characteristics differentiate the cooling meter application from the heat meter appli- cation: • The supply temperature is lower than the return temperature, i.e. Tsupply = Tc, Treturn = Th. • The temperature difference is in the range of 1 … 15 K. This means that, for the same energy consumption, the flow rate is markedly higher than in heating applications. -
Page 20: Flow Meter Application
9.1.4 Flow meter application As a flow meter/calculator, the signals from the flow sensors are converted into current values and cumulative volumes. The measured liquid is also called a ‘heat transfer medium’ in this function, although only the flow rate is measured. A flow meter can be realised in each logical calculator. -
