Proline Prosonic Flow 93T Portable Technical data
Endress+Hauser 59
Connecting cable (sensor/
transmitter)
Only use the connecting cables supplied by Endress+Hauser.
Different versions of the connecting cables are available ä 49.
• Cable material: PTFE
• Cable lengths: 5 m (16.4 feet), 10 m (32.8 feet)
!
Note!
To ensure correct measuring results, route the connecting cable well clear of electrical machines
and switching elements.
Potential equalization For potential equalization, no special measures are necessary.
10.1.6 Performance characteristics
Reference operating
conditions
• Fluid temperature: +20 to +30 °C
• Ambient temperature: +22 °C ± 2 K
• Warm-up period: 30 minutes
Installation:
• Sensors and transmitter are grounded.
• The measuring sensors are correctly installed.
Maximum measured error The measured error depends on a number of factors. A distinction is made between the measured
error of the device (Prosonic Flow 93T = 0.5 % of the measured value) and an additional
installation-specific measured error (typically 1.5 % of the measured value) that is independent of
the device.
The installation-specific measured error depends on the installation conditions on site, such as the
nominal diameter, wall thickness, real pipe geometry, fluid, etc.
The sum of the two measured errors is the measured error at the measuring point.
