‣
When insulating, ensure that a sufficiently large area of the housing support remains
exposed.
The uncovered part serves as a radiator and protects the electronics from overheating and
excessive cooling.
NOTICE
Electronics overheating on account of thermal insulation!
‣
Observe the maximum permitted insulation height of the transmitter neck so that the
transmitter head and/or the connection housing of the remote version is completely
free.
‣
Observe information on the permissible temperature ranges .
‣
Note that a certain orientation might be required, depending on the fluid temperature

Vibrations
The correct operation of the measuring system is not affected by plant vibrations up to 1 g,
10 to 500 Hz. Therefore no special measures are needed to secure the sensors.

Installation for delta heat measurements
Order code for "Sensor version", option 3 "Mass flow (integrated temperature measurement)"
The second temperature measurement is taken using a separate temperature sensor. The
measuring device reads in this value via a communication interface.
• In the case of saturated steam delta heat measurements, the Prowirl 200 must be
installed on the steam side.
• In the case of water delta heat measurements, the Prowirl 200 can be installed on the
cold or warm side.
In the case of saturated steam delta heat measurements, the value 0 bar abs. must be
set in the Fixed process pressure parameter (→  77) in order for the measuring
device to calculate on the saturated steam curve.
