Function and system design

Measuring principle The thermal principle operates by monitoring the cooling effect of a gas stream as it passes over a

heated transducer (PT100). Gas flowing through the sensing section passes over two PT 100 RTD transducers one of which is used conventionally as a temperature sensing device, whilst the other is used as a heater. The temperature sensor monitors the actual process values whilst the heater is maintained at a constant differential temperature above this by varying the power consumed by the sensor. The greater the mass flow, the greater the cooling effect and power required to maintain the differential temperature. The measured heater power is therefore a measure of the gas mass flowrate.

Measuring system The measuring device consists of a transmitter and a sensor. Two versions are available:

• Compact version: transmitter and sensor form a mechanical unit.

• Remote version: transmitter and sensor are mounted separately from one another.

Measuring range Air under ambient conditions

The measuring range is dependant on the gas selection, line size and use of flow conditioner. Each measuring device is calibrated individually with air. A mathematical conversion is performed in the device to adapt to customized gases. The table below defines the ranges available for air without a flow conditioner. To obtain information on other gases and process conditions, please contact your Endress+Hauser sales center, or use the Applicator selection software.

The flow rates shown are representative of the calibrated conditions only and do not necessarily reflect what the meter can measure under operating conditions and actual internal pipe dimensions found on site. To correctly size and select a meter, it is recommended that you either contact your local Endress+Hauser sales center or use Endress+Hauser's "Applicator" software package.

Special applications

High gas velocities (>70 m/s)

In the event of high gas velocities, it is advisable to read in the process pressure dynamically or to enter the pressure very precisely as a velocity-dependent correction is performed.

Light gases

• Due to the very high thermal conductivity of hydrogen (H hydrogen is the lightest of all gases, it can prove very difficult to reliably measure this gas. Depending on the application, the flow rates of hydrogen are often particularly slow and the flow profiles are not sufficiently developed. It is not unusual for the flows to be in the laminar range, whereas a turbulent flow regime would be required for optimum measurement.

• Despite loss of accuracy and linearity in hydrogen applications with low flow rates, the t-mass 65 measures with good repeatability and is therefore suitable for monitoring flow conditions (e.g. leak detection).

• A linear, reliable measured value is difficult to obtain in applications with light gases with a Reynolds number below RE 4000. While this can be improved by making a special adjustment in the lower flow range, a loss of accuracy and linearity should be expected. It is advisable to contact your Endress+Hauser sales center if your application involves media with Reynolds numbers below RE 4000.

• When mounting, please note that the recommended upstream distances should be doubled for very light gases such as helium and hydrogen.  ä 17

Note! The current input can be configured for pressure, gas analyzer: The measuring device can read out the composition of the gas from the gas analyzer and automatically update the first two components (e.g. GAS TYPE 1 and 2) in the programmed gas mixture. This makes a more accurate measurement available even in the case of variable gas compositions, e.g. variable methane and carbon dioxide components in a biogas application.

Installation

Thermal meters require a fully developed flow profile as a prerequisite for correct flow measurement. For this reason, please note the following points when installing the device.

Orientation • The thermal dispersion principle is sensitive to disturbed flow conditions.

• Observe the recommended inlet and outlet requirements.

• Good engineering practice is necessary for the associated pipe work and installation.

• Ensure correct alignment and orientation of the sensor.

• Take measures to reduce or avoid condensation (e.g. install a condensation trap, thermal insulation, trace heating system etc.).

• The maximum permitted ambient temperatures and the medium temperature range ( ä 23) must be observed.

• Install the transmitter in a shaded location or use a protective sun shield.

• For mechanical reasons, and in order to protect the pipe, it is advisable to support heavy sensors.

In the case of saturated or unclean gases, upward flow in a vertical pipe section is preferred to minimize

condensation/contamination.

Not recommended if the vibrations are high or if the installation is unstable.

Only suitable for clean/dry gases. Do not mount the sensor from the bottom, on horizontal pipes, if build-

ups or condensate are likely to be present. Mount the sensor in a position as indicated below

If the gas is very wet or saturated with water (e. g. biogas, undried compressed air), mount in inclined

orientation (approx. 135° ±10°).
