“Decrease” means that the temperature of a measured
fluid drops rapidly, while “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.
∆T: Change in temperature of measured fluid in one
second
Flow velocity: flow velocity of the measured fluid
Allowable Conditions for Cleaning Sanitary Type
Linings
Steam or hot water cleaning: Max.temp.= +150 °C
(+302°F), time= 60 minutes or less
Vibration Conditions:
Level of vibration in conformity with IEC 60068-2-6
(SAMA 31.1-1980)
• Integral Flowmeter: 1 G or less (frequency 500 Hz or
less)
• Remote Flowtube (size 2.5 to 400 mm (0.1 to 16 in.)):
2 G or less (frequency 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.
