Function and system design
Measuring principle
T09-DTT31xxx-15-xx-xx-xx-000
The device measures the mass flow of a liquid medium with the calorimetric measurement method. The
calorimetric measuring principle is based on cooling a heated temperature sensor. Heat is removed from the
sensor by forced convection due to medium flowing by. The extent of this heat transfer depends on the medium
velocity and the difference in temperature between the sensor and medium (King's law). The higher the
velocity or the mass flow of the medium, the greater the temperature sensor cooling.

Power supply failure • Behaviour in case of overvoltage (> 30 V)
The device works continuously up to 34 V DC without any damage.
No damage is caused to the device in case of a short-term overvoltage up to 1 kV (as per EN 61000-4-5).
The specific properties are no longer guaranteed if the supply voltage is exceeded.
• Behaviour in case of undervoltage
If the supply voltage drops below the minimum value, the device switches off (status as if not supplied with
power = switch open).
Performance characteristics
The percentage information in the "Performance characteristics" section refers to the full scale value or the set
maximum value (100% value) of the monitoring range.
Reference operating
conditions
As per DIN IEC 60770 or DIN IEC 61003
T = 25 °C ± 5 °C (77 °F ± 9 °F), relative humidity 45 to 75 %, ambient air pressure 860 to 1060 kPa
(124 to 153 PSI), water test medium. Supply voltage U = 24 V DC.
Maximum measured error Flow
The device records fluid velocity relatively in relation to a set monitoring range of the flow (0 to 100 % as
display value). An absolute measurement of the fluid velocity or the mass flow is not possible. The sensitivity
of the calorimetric flow sensor changes with the fluid velocity. It increases with decreasing fluid velocity (for
example, with water, the greatest sensor sensitivity is recorded in the range from 0.03 to 0.5 m/s).

• Electrical rotation of display by 180°
• Housing can be rotated up to 310 ° mechanically
Orientation
No restrictions, but self draining.
Inlet and outlet run
The sensor requires a fully developed flow profile for correct monitoring. For this reason, steadying sections

• The sensor tip should be completely surrounded by medium.
• Position the sensor tip in the area of maximum fluid velocity
(pipe center).
• Minimum sensor immersion length: Li≥10 mm (0.4 in)

Installation conditions
Orientation
• For horizontal pipes: lateral installation.
!Note!
Installation from above only if the pipe is completely filled
with medium.
• For vertical pipes: installation in the ascending pipeline.
