Measuring arrangement for determining amount of heat

A measuring arrangement, comprising:

• a heat meter having a flow sensor;
• a first temperature sensor;
• a second temperature sensor;
• and
• computing means, wherein:
• said flow sensor serves to register volume or mass of a heat transport medium flowing in a feed line or a drain line of a heat exchanger;
• said first temperature sensor serves to register a temperature in the feed line of the heat exchanger;
• said second temperature sensor serves to register a temperature in the drain line of the heat exchanger;
• said computing means serves to calculate, by means of the measurement signals output by said flow sensor and said first and second temperature sensors, the amount of exchanged heat;
• a first transfer function, which serves to determine the temperature in the feed line based on a measurement signal of said first temperature sensor, is stored in the computing means;
• a second transfer function is stored in the computing means;
• wherein the first transfer function differs from the second transfer function;
• the second transfer function serves to determine the temperature in the drain line based on a measurement signal of said second temperature sensor;
• parameters serving to determine the first and second transfer function are stored in a memory unit of said computing means;
• the first and second transfer functions are Callender-van Dusen equations, and the parameters are coefficients of the Callendar-van Dusen equations and the coefficients of the Callender-van Dusen equation for the first and the second temperature sensors are individually ascertained for each temperature sensor.
