“Decrease” means that the temperature of a measured
fluid drops rapidly, “Increase” means that the temperature
rises rapidly. The maximum allowable ranges in both
cases are indicated by the curves shown in the diagrams,
with the solid line indicating the maximum increase, and
the broken line the maximum decrease.

time= 60 minutes or less
Vibration Conditions:
Level of vibration in conformity with IEC 60068-2-6
(SAMA 31.1-1980)
• Integral Flowmeter:
9.8 m/s

or less (frequency of 500 Hz or less)
Note: Avoid locations with much vibration (where the pipe
vibration frequency is 500 Hz or more), which may
cause damage to the equipment.
