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.

Installation

a

Proline t-mass A 150

Mounting location

Orientation

Thermal measuring devices require a fully developed flow profile as a prerequisite for correct flow
measurement. For this reason, please pay attention to the following points and document sections
when installing the device:

• Avoid flow disturbances, as the thermal measuring principle reacts sensitively to them.

• Take measures to avoid condensation (e.g. condensation trap, thermal insulation etc.).

The direction of the arrow on the sensor helps you to install the sensor according to the flow direction (direction
of medium flow through the piping).

Requirement for pipework

A0015773

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

2) Suitable only for clean and dry gases. If buildup or condensate are always present: Mount the sensor in an inclined
position.

3)

Select inclined mounting position (a = approx. 135°) if the gas is very wet or saturated with water.

The measuring device must be professionally installed, and the following points must be observed:

• Piping must be professionally welded.

• Seals must be sized correctly.

• Flanges and seals must be correctly aligned.

• The internal pipe diameter on the inlet side must match the internal diameter of the process connection

ordered. The maximum permitted deviation between the internal diameters is:
1 mm (0.04 in)

• Following installation, the pipe must be free from dirt and particles in order to avoid damage to the sensors.

The thermal measuring principle is sensitive to disturbed flow conditions.

• As a general rule, the measuring device should always be installed as far away as possible from any flow
disturbances. For further information, please refer to ® ISO 14511.

• If possible, the sensor should be installed upstream from valves, T-pieces, elbows etc. To attain the specified
level of accuracy of the measuring device, the below mentioned inlet and outlet runs must be maintained at
minimum. If there are several flow disturbances present, the longest specified inlet run must be maintained.

å 6 Recommended inlet and outlet runs when using a flow conditioner

This is a special Endress+Hauser design which was developed for the sensor t-mass A 150 (DN 40 to 50 / 1
½ to 2"). The arrangement of the individual screw holes and their diameter means that the flow conditioner
can be used for different flange pressure ratings.

The flow conditioner and the seals are installed between the pipe flange and the measuring system. To ensure
correct centering of the flow conditioner, use only standard screws which match the screw holes .

Please note that the flow conditioner must be mounted in such a way that the alignment notch is pointing in
the direction of the transmitter. Incorrect installation could have a negative effect on the measurement accuracy.

• Not suitable for lap joint flange or threaded versions!

• Order the 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 flow conditioners from other suppliers will affect the flow profile and pressure drop and will
have an adverse effect on performance.

• Screws, nuts, seals etc. are not included in the scope of supply and must be provided by the customer.

The pressure loss for flow conditioners is calculated as follows:

Dp = Pressure loss [mbar]
r = Density [kg/m3]

K = Constant 1876 (SI units) or 8.4 · 10-7 (US units)

Calculation example

• g = 412 kg/h

•

r = 8.33 kg/m3 at 7 bar abs. and 20 °C (68 °F)

• D = 42.8 mm for DN 40, PN 40

Calculation in SI units

Dp = 1 876 · (4122 ¸ 8.33) · (1 ¸ 42.84) = 11.4 mbar

Environment

g = Mass flow [kg/h]
D = Diameter [mm]

The devices can be ordered with or without a PED approval. If a device with a PED approval is required, this
must be explicitly stated in the order.

• With the PED/G1/x (x = category) marking on the sensor nameplate, Endress+Hauser confirms compliance
with the "Essential Safety Requirements" specified in Annex I of the Pressure Equipment Directive 97/23/
EC.

• Devices bearing this marking (PED) are suitable for the following types of medium:
Media in Group 1 and 2 with a vapor pressure greater than, or smaller and equal to 0.5 bar (7.3 psi)

• Devices not bearing this marking (PED) are designed and manufactured according to good engineering
practice. They meet the requirements of Art.3 Section 3 of the Pressure Equipment Directive 97/23/EC.

• Memory volume is extended from 20 message entries (basic version) to up to 100 entries.

• Message entries are visualized via the local display or FieldCare.

Data logging (line recorder):

• Memory capacity for up to 1000 measured values is activated.

• 250 measured values can be output via each of the 4 memory channels. The recording
interval can be defined and configured by the user.

• Data logging is visualized via the local display or FieldCare.

Description

Order the t-mass A 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.
