No updating of display values
No power supply
Replace battery or check mains supply
No display function (blank
display)
No power supply and backup
Replace back-up cell. Replace battery or
check mains supply
No accumulation of m³
No volume pulses
Incorrect connection
Check flow sensor connection
(Check with PULSE TESTER, if necessary)
Flow sensor is inverted
Check flow sensor direction
Air in sensor/cavitation
Check installation angle. Check if there is
air in the system or cavitation from valves
and pumps. If possible, try to increase the
static pressure
Flow sensor error
Replace the flow sensor/send meter for
repair
Erroneous accumulation of m³
Erroneous programming
Check that meter factors of calculator and
flow sensor correspond
Air in sensor/cavitation
Check the installation angle. Check if there
is air in the system or cavitation from valves
and pumps. Increase the static pressure, if
possible
Flow sensor error
Replace the flow sensor/send sensor for
repair
