minutes.
Function, menu 4.3.1
The digital output 2 (relay contact) can be configured for reporting device status (device fault,
measuring error), flow direction or a limit for flow, US velocity, US amplitude.
Possible alarm states are as follows:
• Alarm - device state status
• Flow direction forward
• Flow min - flow below lower limit
• Flow max - flow above upper limit
• Flow min/max - flow either under below limit or above upper limit
• Min/max US velocity
• Max US level
• Min US level
• Min/max US amplitude
• Max US amplitude
• Min US amplitude
• No function
Note
The relay contact is open when “no function” is set.
