FLUID OPERATING
TEMPERATURE:
0° C to +98° C (NPT & BSPP)
0° C to +82° C (Polymer and Steel Flanges)
(Do not allow fluid to freeze inside meter.)
STORAGE
TEMPERATURE:
–40° C to +108° C
AMBIENT AIR
OPERATING
TEMPERATURE
-18° C to +60° C
ALL METERS
There is a correlation between ambient air temperature
and maximum fluid operating temperature. As ambient
air temperature increases, the maximum fluid operating
temperature decreases. See Maximum Temperature Conditions
graph named “TEMPERATURES” on page 16 to verify that
your process is within allowable meter operating limits.
