Indicator
The digital LCD indicator (optional) indicates engineering
units and can be set freely between -99999 and 99999 (5
digits). For meter calibration, specify the following items
when placing your order
• Meter calibration range
• Meter calibration unit
• Linear / Square-root for meter indication.
Bolts and nuts materials (for fastening
meter body cover)
Carbon steel (SNB7), 304 SST, 630 SST
Paint
OPTIONAL SPECIFICATIONS
Oil free finish
The transmitter is shipped with oil-free wetted parts.
Adapters for anticorrosion materials
These are adaptor flanges to connect 82 mm pipes made of
anticorrosion materials [excluding ASTM B575 (Equiva-
lent to Hastelloy C-276)] to 54 mm general-purpose pipes.
External zero/span adjustment function
The transmitter can be easily zero/span adjusted in the
field.
Elbow
This is an adaptor for changing the electrical conduit con-
nection port from the horizontal to the vertical direction, if
required by wiring conditions in the field. One or two
elbows may be used as needed.
Conformance to Non SI units
We deliver transmitters set to any Non SI units as speci-
fied.
