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 flow line 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).
