WATER METER
This menu allows you to set the operation mode of a pulse emitting water meter connected to the "LOTUS AIR" system.
Enter this menu by selecting “MENU’” from the main screen, enter the PASSCODE and select “WATER METER”. Save the
settings by selecting “ESC”, then confirm the changes by moving to “YES” and pressing the knob.
Mode
This function allows you to set the display mode and to calculate the reading scale of the pulse emitting water
meter connected to the "LOTUS AIR" system. The possible configurations are:
IMP/LTR (calculation based on number of pulses set in VALUE for each litre)
LTR/IMP (calculation based on number of litres set in VALUE for each pulse)
mA (calculation based on RESOLUTION and MAXFLOW)
Value
Setting the operation mode on “IMP/LTR” or “LTR/IMP” defines the number of pulses or litres necessary to
complete a single unit for each pulse or litre.
Max.Flow (cbm/h) & Resolution
Set these values if you use the mA calculation method. Max Flow defines the maximum value of the flow in
cbm/h (cubic meters per hour) to achieve compared with the highest resolution mode of 20mA.
Resolution determines the operation of the pulses based on the incoming signals received in 0/20mA or
else 4/20mA. It is recommended to perform the calibration of this incoming signal, after having chosen the
configuration type (see page 28)
TIMEOUT
If no more pulses are received from water meter during seconds set (e.g.: 20s, max 99s) then "LOTUS AIR"
system will end the dosage .
