Care must be taken when installing transmitters on hot processes. The
operating temperature limits for the device (as outlined in Table 5) must
not be exceeded. Impulse piping may be used to reduce the temperature
of the process that comes into contact with the transmitter meter body.
As a general rule there is a 56 degree C drop (100 degree F) in the
temperature of the process for every foot of ½ inch uninsulated piping.
Table 13 describes typical process connections for a given type of
transmitter.
