Technical data Proline Prowirl R 200 HART
180 Endress+Hauser
If the measuring device does not have pressure or temperature compensation
3)
, it is
recommended that external pressure measurement values be read in so that the following
measured variables can be calculated:
• Energy flow
• Mass flow
• Corrected volume flow
Integrated pressure and temperature measurement
The measuring device can also directly record external variables for density and energy
compensation.
This product version offers the following benefits:
• Measurement of pressure, temperature and flow in a true 2-wire version
• Recording of pressure and temperature at the same point, thus ensuring maximum
accuracy of density and energy compensation.
• Continuous monitoring of pressure and temperature, thus enabling complete integration
in Heartbeat.
• Easy testing of pressure measurement accuracy:
– Application of pressure by pressure calibration unit, followed by input into measuring
device
– Automatic error correction performed by device in the event of a deviation
• Availability of calculated line pressure.
Current input
The measured values are written from the automation system to the measuring device via
the current input → 179.
HART protocol
The measured values are written from the automation system to the measuring device via
the HART protocol. The pressure transmitter must support the following protocol-specific
functions:
• HART protocol
• Burst mode
