Proline t-mass 65 PROFIBUS DP/PA Technical data
Hauser 115
1. The full scale value depends on the nominal diameter of the device and the maximum
flow capacity of the calibration rig. The full scale values are listed in the following
section.
2. A flow conditioner is also supplied.
Repeatability ±0.5 % of reading for velocities above 1.0 m/s (0.3 ft/s)
Response time Typically less than 2 seconds for 63 % of a given step change (in either direction).
Influence of medium
pressure
(Pressure co-efficient) Air: 0.35 % per bar (0.02% per psi) of process pressure change
K Q = 100 to 150 %:
±1.5 to ±5 % of the current
measured value increasing
linearly as expressed in the
following equation:

5-point, traceable ISO/IEC17025:
The measuring device is calibrated
and adjusted on an accredited and
traceable calibration rig and its
accuracy is certified in a Swiss
Calibration Services (SCS) calibration
report (5 control points), which
confirms traceability to the national
calibration standard.
