Operation
• To save power, the water flow meter switches off automatically after 1 minute if no flow is
measured. Briefly press the control button (3) to switch on.
The total flow rate and the internal values for calculating the average daily flow rate
remain stored after automatic shut-off.
• You can switch between the different displays by briefly pressing the control button.
1 Flow rate per minute (automatically extrapolated value, depending on the current flow rate)
If you see this display, you can switch between L/Min (litres per minute) and GAL/min
(gallons per minute) by pressing and holding the control button for approx. 2 seconds.
The set unit (L or GAL) is also used for the following displays (2, 3, and 4).
2 Measured flow rate or water consumption
Press and hold the control button for approx. 2 seconds to manually reset the value (if the
water flow meter switches off automatically after 1 minute, the value is automatically reset
to “0”).
3 Average daily flow rate or water consumption, averaged over the past 7 days; counting/cal
-
culation is done on the next day
Press and hold the control button for approx. 2 seconds to manually reset the value.
4 Previous total flow rate or total water consumption
Press and hold the control button for approx. 2 seconds to manually reset the value.
Overwintering
The water flow meter must be put into storage when temperatures are around or below freez
-
ing. Allow residual water to drain out. Remove the battery from the battery compartment and
store the water flow meter in a dry, frost-free location over the winter.
In the event of frost, the water will freeze inside the flow meter; the higher volume of
ice will destroy the watering timer and void the warranty!
Cleaning and maintenance
There are no serviceable parts in the water flow meter – never open or disassemble it (except
for inserting/replacing the battery as described in these operating instructions). Maintenance,
repair and associated dismantling may only be carried out by a specialist or a specialist work
