Function and system design

Proline t-mass A 150

Measuring principle

Measuring system

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).

Operable flow range

Over 100:1 (over 150:1 for calibration option code K).

Even in the extended measuring range (above the calibrated end value), the flow rate is captured and provided as an output signal. However, the extended range is not subject to the specified measuring uncertainty.
