Important:
The meter pipe must be completely filled to ensure proper
measurement. The function "Detector empty pipe" can be
used to continuously monitor this condition. If the fluid
level drops below the electrode level, all outputs can be
automatically set to zero. This ensures false pulses or
incorrect displays are avoided when the meter pipe is
empty. In addition to the message in the display, this
condition can be reported via the switch contact output. If
the meter pipe is filled, the error message "empty pipe" is
turned off and the meter returns to normal operation.
