2.4 Temperature differential and thermal shock
Temperature differential Temperature differential Temperature differential Temperature differential
The maximum difference between ambient temperature and process (operating) temperature is
110°C / 230°F.
Thermal shock Thermal shock Thermal shock Thermal shock
Thermal shock occurs when there is a sudden and extreme change (shift) in process
temperature. To avoid thermal shock, refer to the following table for the maximum temperature
shift.
Meter Meter Meter Meter Maximum temperature shift Maximum temperature shift Maximum temperature shift Maximum temperature shift
S15 +80°C / +176°F
S25
S40 +110°C / +230°F
S50
CAUTION!
Operation outside these limits may result in shifts in density and mass flow calibration. Repeated
shocking may also lead to premature failure of the meter! However, higher thermal shocks are
possible at lower working pressures. For more information, please contact your nearest
representative.
