Pres. shock sup. 
Navigation  Expert → Sensor → Process param. → Low flow cut off → Pres. shock sup. (1806)
Prerequisite One of the following options is selected in the Assign variable parameter (→  79):
• Mass flow
• Volume flow
• Correct.vol.flow
Description Use this function to enter the time interval for signal suppression (= active pressure shock
suppression).
User entry 0 to 100 s
Factory setting 0 s
Additional information Description
Pressure shock suppression is enabled
• Prerequisite:
– Flow rate < on-value of low flow cut off
or
– Changing the flow direction
• Output values
– Flow displayed: 0
– Totalizer: the totalizers are pegged at the last correct value
Pressure shock suppression is disabled
• Prerequisite: the time interval set in this function has elapsed.
• If the flow also exceeds the switch-off value for low flow cut off, the device starts
processing the current flow value again and displays it.
Example
When closing a valve, momentarily strong fluid movements may occur in the pipeline,
which are registered by the measuring system. These totalized flow values lead to a false
totalizer status, particularly during batching processes.
