Function and system design
Measuring principle The thermal measuring principle is based on the cooling of a heated resistance thermometer (PT100), from
which heat is extracted by the passing gas. The gas passes two PT100 resistance thermometers in the
measurement section. One of these is used in the conventional way as a temperature probe, while the other
serves as a heating element. The temperature probe monitors and records the effective process temperature
while the heated resistance thermometer is kept at a constant differential temperature (compared to the
measured gas temperature) by controlling the electrical current used by the heating element. The greater the
mass current passing over the heated resistance thermometer, the greater the extent to which cooling takes
place and therefore the stronger the current required to maintain a constant differential temperature. This means
that the heat current measured is an indicator of the mass flow rate of the gas.

Measuring range The available measuring range depends on the choice of gas, the size of the pipe and the use of a flow conditioner.
The measuring device is calibrated with air (under ambient conditions) and the value is converted in order to
adapt it to the customer's gas if necessary.
To obtain information on other gases and process conditions, please contact your Endress+Hauser sales
office.
To calculate the measuring range with and without a flow conditioner (option L (® ä 12)
(® ä 15)), use the Applicator (® ä 31) product selection tool.
The following tables list the ranges available for air (without flow conditioner).
