Meter Setup:
Leak Alarm: set this to the period that the premises is
unattended (usually 4 hours). If no consumption occurs
within the (4 hour) period every day then there is no alert.
Time Alarm: allows an alarm to be raised if there is
continuous consumption for the set period of time. For
example, when set to 20 min, an alarm would be raised if
a hose was left running for more than 20 minutes.

from the water meter output to litres and must be set at
installation time.
Serial Number: See below.
Tank Setup:
Level Alarm: allows an alarm to be raised if the tank level
falls below the set value, for example 10%.
Time Alarm: allows an alarm to be raised if the level
continuously falls for the set period of time. For example,
when set to 1 hour, an alarm would be raised if the water
level was falling for more than 1 hour.
Tank Capacity: the nominal volume of the tank.
Tank Height: the distance from the bottom of the tank to
the bottom of the overflow pipe (ie maximum height of
water) in millimetres.
Set New Level: use this setting to calibrate the water
level in the tank. Measure the water level from the bottom
of the tank and enter the value in millimetres.
Serial Number: See below.
Serial Number:
Every sensor has a unique serial number that needs to be
entered into the Display Unit to allow a wireless connection
to be made between the sensor and Display Unit. The
serial number is located inside the battery cover of each
sensor. To install a new sensor enter the serial number
using the Display Unit menu system. If the serial number
is incorrect then a wireless connection cannot be
established between the sensor and the Display Unit.
FAQs and Troubleshooting
Battery Replacement – Tank Sensor
The Tank Sensor contains batteries that can be replaced by
removing the top cover (grey in colour) from the unit.
When replacing batteries ensure the battery polarity is
correct, as shown on the inside of the battery cover.
Suitable Batteries – Tank Sensor
Use rechargeable AA cell, 1.2 or 1.5V, minimum
recommended capacity 2100mAh.
Battery Performance
The Display Unit indicates the sensor battery condition to
show when a battery change is required. The following
tips will help to ensure good battery life:
• Keep the Display Unit powered on. When the Display
Unit is off the sensors scan for a wireless connection
more often and therefore consume more power.
• Use only the recommended type, voltage and capacity
(mAh rating) of batteries.
• Locate the sensor in a cool, dry environment.
Battery Status Indication
The Status Bar (see Information Display) shows a battery
icon representing the lowest battery health of all connected
sensors. The battery health of each sensor is shown on the
Status screen.
Clearing Data
The Display Unit stores internal data to allow display of
information such as quarterly consumption. When the
Display Unit is first powered up and after the date and time
have been set, the display prompts the user to clear the
data. Answering YES to this question will erase all internal
stored information including quarterly, weekly and daily
consumption figures. Normally one would only answer YES
when the Display Unit is moved to a new site or
installation.
Resolution of Inflows and Consumption
The Tank Monitor calculates inflows and consumption
based on changing levels within the tank. This means that
the resolution of readings depends on the surface area of
the tank. For example, a 2 metre diameter tank will have
better consumption and inflow measurements than a 5
metre diameter tank.
For applications where it is required to accurately meter
the consumption from the tanks, it is recommended to fit a
water meter and Aquamonitor Mains Sensor on the
pressure side of the pump.
Pre-Installation
Installing Display Unit
Choose a location for the Display Unit, which must be within
wireless range of the sensors. The wireless range will depend
on the presence of objects, such as walls and vegetation,
between the Display Unit and each sensor.
The Display Unit can be
wall mounted using the wall
bracket. To place it on a
bench remove the wall
bracket and rotate the foot-
stand outwards.
Wireless range is usually
best when the sensor and
Display Unit are located
away from the ground and
the antenna is not sitting
on a surface.
Step 1: Unpack the Display Unit and connect the DC power
adaptor to the Display Unit and switch the power on at the
wall. Use the buttons to set the time and date and day of
week. Answer NO to the question to clear values.
Step 2: Referring to the Menu Guide, enter the menu system
by pressing the OK button. Use the menu to set the number
of users, Tank height and volume and alarm settings. The
date and time can also be changed if needed.
Battery Insertion – Tank Sensor
Step 3: Fit the AA batteries and check the polarity (+ and -)
which is shown inside the battery cover. Once the batteries
are in place, push the battery compartment cover back on
whilst observing the LED through the recessed hole in the
cover and check that it flashes briefly. If the LED indicator
doesn’t flash then check the orientation and type of battery
used.
Check Wireless Connection
Step 4: Observe the Display Unit after a few minutes to check
that a wireless connection has been established.
Step 5: Use the Display Unit menu to enter the height of the
tank from the bottom of the tank to the roof, in millimeters. If
the roof is sloped then measure from the outside edge of the
roof (the lowest point of the roof) to the bottom of the tank.
Step 6: Next, enter the tank size in litres. Some tanks may
have this stamped on the roof or you may obtain the capacity
from the tank manufacturer or supplier. If this information
cannot be found then please contact Aquamonitor Support.
Tank Sensor Installation
The Tank Sensor mounts to the top (roof) of the tank on the
outside. The best location is toward the middle of the tank
and/or at the highest point of the tank and away from the
edges. Ensure that the location of the sensor has a clear line
of sight to the bottom of the tank. Internal structures between
the sensor and the bottom of the tank will limit the
measurement range.
Before fitting the Tank Sensor to the top (roof) of the tank,
place the sensor in the desired location and check the wireless
connection to Display Unit.
Placing and Securing Tank Sensor
Step 1: Check that:
• There is a wireless connection with the Display Unit.
• The sensor is not near side of the tank (more than
500mm).
• The distance from the maximum water level and the
sensor is at least 300mm.
• There is a clear line of sight to the bottom of the tank.
Step 2: The Tank Sensor has been designed to allow for tanks
with a sloped roof. When fitting the sensor, position the unit
across the gradient of the tank. This will allow the angle to be
set to counter for the gradient.
Step 3: Using the drilling template supplied, provide the
mounting holes in a removable lid or in the roof of the tank.
Remove the battery cover from the sensor.
Step 4: Fit the P clips to the sensor head first then screw the
P clips into place around the centre hole.
Step 5: Observe the spirit level guide and adjust the level to
vertical before tightening the screws holding the P clips.
Step 6: Fold the top half of the sensor over to cover the
sensor head and fasten the body of the sensor to the roof of
the tank using four screws and refit the battery cover.
