Another piping arrangement uses a block-off valve and a tee connector in the process piping to the
transmitter as shown in Figure 3-2.

ATTENTION
For liquid or steam, the piping should slope a minimum of 25.4 mm (1 inch) per 305 mm (1
foot). Slope the piping down towards the transmitter if the transmitter is below the process
connection so the bubbles may rise back into the piping through the liquid. If the transmitter is
located above the process connection, the piping should rise vertically above the transmitter;
then slope down towards the flowline with a vent valve at the high point. For gas
measurement, use a condensate leg and drain at the low point (freeze protection may be
required here).
CAUTION
Property damage may result if operating temperature limits of transmitter are exceeded.
Electronics housing must not exceed 85° C [185° F], meterbody temperature limit may be
rated higher. Consult transmitter nameplate for meterbody temperature limits. To reduce
the temperature of the process that comes into contact with the transmitter meter body, install
impulse piping. As a general rule there is a 56 degree C drop (100 degrees F) in the
temperature of the process for every foot (305 mm) of ½ inch uninsulated piping.
