EZ CAL OPTION

1. The transmitter is delivered with a logo nameplate in place
of the EZ CAL option. Lift up on the logo nameplate to snap its
tab out of the EZ CAL option mounting hole.
2. Position the EZ CAL option on the top of the transmitter as
shown in Figure 3-1 and install the mounting screw.
Consider the corrosive properties of the measured substance
when selecting piping materials. Degradation of the piping can
upset the process. Some process upsets can injure personnel
and damage equipment.
Piping should be in accordance with ANSI Code B31.1 for pres-
sure piping.
When pressurizing, avoid overloading and pressure hammer.
Refer to the introduction section for the pressure limits of the
cell. Exceeding this pressure could result in damage to the cell
and cause serious injury to personnel.
The piping shown in Figures
ing arrangements only. They are intended as generalized
guides, and may not necessarily reflect the exact configuration
required for the particular service. As a general rule:
If possible, mount the transmitter with the flanges vertical.
•
Mounting the transmitter with the flanges other than verti-
cal causes a zero offset due to the weight of the fill oil in
the cell. If the transmitter must be mounted with the
flanges other than vertical, refer to
zero.
If using in corrosive processes, avoid splashes on the
•
transmitter.
Prevent obstruction of the pressure connections by solid
•
matter of products coming from the piping.
Be sure the wet legs in the pressure piping are full.
•
Avoid sudden temperature variations.
•
Wet legs (and possibly the transmitter) should be heated to
•
prevent freezing.
Make the impulse lines as short as possible.
