1.1 Calorimetric monitoring procedure

The calorimetric measuring procedure is based on the physics of heat dissipation.

A body with a temperature higher than its surroundings supplies a medium flowing past that body with energy in the form of heat. The amount energy supplied is a function of temperature difference Δϑ and mass flow.

The thermal measuring method CTD (Constant-Temperature-Difference) is based on following principle:

The temperature difference Δϑ between the two sensors is kept constant and the mass flow is determined by measuring the calorific power.

Fig. 1 is a schematic diagram of a CTD method based sensor.

Two temperature-sensitive resistors (sensor elements RS and RM) are immersed in the medium. Sensor RM assumes the temperature of the medium ϑM whilst heater resistor RH heats element RS to temperature ϑS. As a function of the medium, the temperature differential Δϑ = ϑS - ϑM is preselected as a reference variable by the CTD control and is kept constant. The required heater current IH is a function of mass flow so that the control variable y of the control can be used for evaluation.

Major benefits of this method are:

●Fast response, particularly to sudden flow standstill.

●Medium temperature measurement, providing optimum temperature compensation.

●Increased safety because the sensor cannot be overheated during flow standstill. The flow rate is determined by mass flow.
