The connection port (G1/4 (PF1/4), female) for the process pressure piping is located
on the bottom of case.
Proper piping may differ depending on the process condition and the instrument
installation. Generally, attention should be paid to the following points.
(1) Provide a stop valve in the pressure connection tube so as to allow maintenance
operation without interrupting the process.
(2) Provide a cock for drain and air release. In case of a horizontal piping, provide a
gradient of 1/100 or more.
(3) If the process pressure largely pulsates or varies, provide a pulsation preventing
means to smooth out pressure. (Please consult an Azbil Corp. representative on a
special case.)
