Function and system design
Measuring principleThe 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 systemThe 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 rangeAir 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.
Measuring range for the EN (DIN)/JIS flanged versions, metric units:
DNkg/hNm3/h at 0°C, 1.013 bar asft3/min. at 15°C, 1.013 bar a
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.

Inlet and outlet runsThe thermal dispersion principle is sensitive to disturbed flow conditions.
As a general rule, the thermal flowmeter should always be installed as far away as possible from any
flow disturbances. For further information ISO Standard 14511.
• Where two or more flow disturbances are located upstream of the meter, the recommended inlet
length for the flow disturbance causing strongest disturbance must be used. For example if a control
valve is additionally mounted upstream from the measuring device and an elbow on the inlet side,
select the recommended inlet length for control valves: 50 × DN
• For very light gases such as Helium and Hydrogen all upstream distances should be doubled.
The minimum recommendations for inlet and outlet runs (without flow conditioner) are:
A specially designed perforated plate flow conditioner can be installed if it is not possible to observe
the inlet runs required ( ä 17).
Outlet runs with pressure measuring points
The pressure measuring point should be installed downstream of the measuring device, so that there
is no potential influence of the pressure transmitter process connection on the flow entering the
measuring point.

conditioner.
1 = Flow conditioner with the flanged sensor, 2 = Flow conditioner with the insertion sensor
!
Flow conditioner for use with insertion sensors 65I
The well known "Mitsubishi" design is recommended for this application DN 80 mm to DN 300 mm
(3" to 12"). The flow conditioner must be installed at a minimum distance of 8 × DN upstream of the
sensor. A further 5 pipe diameters minimum inlet run is required upstream of the actual conditioner
itself.
Measured errors can occur depending on disturbances in the inlet run. Therefore it is advisable to
choose inlet runs that are as long as possible.
Note!
In the case of insertion devices, the inlet run selected downstream of the conditioner should be as long
as possible.
Perforated plate flow conditioners (19 hole) for use with flanged sensor 65F
This is a special Endress+Hauser version designed especially for use with the t-mass F sensor (sizes DN
25 to 100 (1 to 4")). The mounting hole patterns and sizing are of a multi-variant design which means
that one plate will fit different flange pressure classes e.g. Cl. 150 and Cl. 300.
The flow conditioner and gaskets are fitted between the pipe flange and the measuring device. Use only
standard bolts which match the flange bolt hole to guarantee that the flow conditioner is centered
correctly.
The alignment notch must also be pointing in the same plane as the transmitter. Incorrect installation
of the flow conditioner will have a small effect on the measurement accuracy.

Note
• Order the t-mass F sensor and the flow conditioner together to ensure that they are calibrated
together. Joint calibration guarantees optimum performance. Ordering the flow conditioner
separately and using it with the device will further increase measurement uncertainty.
• The use of conditioners from other suppliers will affect the flow profile and pressure drop and will
have an adverse effect on performance.
• Bolts, nuts, seals, etc. are not included in the scope of supply and must be supplied by the customer.
