The S207E is a wireless tank level indicator for use
on fluid tanks, in septic systems or on other tanks
and cisterns that contain non-flammable liquids.
The Tank Unit is mounted on the top surface of the tank or cistern and uses ultrasonic
signals to detect the liquid level inside. This is then wirelessly transmitted to the
Display Unit. When the button is pressed the lights show you the fluid level.
When you are about to run out the “Low Fluid Level” light flashes to alert you.
Main features and benefits:
• Peace of Mind - know exactly how much fluid is in the tank at any time
• Ultrasonic level measurement - no holes in side of tank or mechanical floats
• Resilient – stands up to all climatic conditions: high winds, rain, snow and
extreme heat
• Stylish – the Tank Unit is low profile and the Display Unit looks good in any
kitchen
• Wireless system - no need for control wires or trenching
• Intelligent – robust and reliable software which notifies you of anything that
needs your attention
• Tough – designed and constructed in New Zealand using materials that
withstand the harshest environment.
Before you install
Try your unit!
1) Insert the batteries supplied in the Display Unit and Tank Unit.
2) Hold the Tank Unit so the ultrasonic signal bounces off a flat reflective surface
such as the floor or wall.
3) Watch the Display Unit update
4) Test the range by leaving the Tank Unit on the top of the tank and walking away
with the Display Unit. If the Display Unit beeps every few seconds the units are in
range. When the Display Unit stops beeping the units are out of range.
Take the batteries out while you read the rest of the manual and find your tools.
Note - Ensure you read the complete manual before installation.

Install Tank Unit
Choose location for Tank Unit on the top of the tank or cistern.
Ideal. Unit in centre
of tank
Incorrect. Mount unit
away from ribbed
walls to prevent signal
reflection off walls
Correct. For buried tanks
mount unit in centre of lid,
or on bracket mounted in
riser
!!
"
For plastic tanks use the supplied screws to attach the Tank Unit to the tank.
For metal tanks first drill 3mm or ¼" holes, and then fasten using the screws.
For concrete tanks drill 6mm or ¼" holes, insert the supplied plastic plugs and then
fasten using the screws.

2. Drill a 50mm (2”) hole in
tank. For thick concrete tanks
make a 75mm (3”) hole.
Measure the depth of
tank to the base (or to the
water outlet). Write this
measurement down.
Insert Tank Unit in hole and
rotate so tank antenna is on
the lower side (to prevent
water entering unit). Ensure
that the transducer cone
underneath is pointing
directly at the surface of the
water.

Note - For tanks less than 1500 mm (5’) deep mount unit in centre of tank.
- Mount unit at least 100 mm (4”) from the high water level.

Tank Unit setup
1. Remove cap from Tank Unit by turning counter-clockwise and insert batteries (supplied).

2. Set Depth. The Tank Unit comes factory
set in test mode. In test mode the Tank Unit
takes a new reading and transmits this data
every few seconds. Once you have checked
communication is working, take the Tank
Unit out of test mode. (Leaving the unit in
test mode will drain the batteries quicker).
In order for the S207E to determine whether
the tank is half full or almost empty, the
depth of the tank must be input.
This is done by changing the position of
the Mode Switch inside the Tank Unit. Use
the measurement taken in and find the
nearest depth on the table to the right.
Change the Mode Switch to the switch
position indicated. Once the Mode Switch has
been set, press the Tank Unit reset button.

Display Unit Set Up
1. Insert batteries into the
base of the Display Unit.
The top light will flash as the
Display Unit calibrates and looks
for the Tank Unit. When the Tank
Unit is found the depth will be
displayed on the Display Unit.
8 lights means the tank is full,
2 lights means it is ¼ full.
Insert 4 x AA batteries
in base of unit
Signal has been lost – if this occurs regularly
check range (see next page)
Replace batteries in Tank Unit
Replace batteries in Display Unit
Reset Display Unit (hold down button).
If error persists reset Tank Unit.
If error still persists check range (see next page)
Tank Unit can not detect range due to
something blocking sensor, or the sensor is not
rotated so it is level with the liquid surface
The tank level has dropped very quickly.
Check for leaks. If this occurs without any fluid
loss, this could be a sign that your sensor is not
level to the water.
The tank is almost empty.
The red LED flashes and the Display Unit beeps.
LED Lights
The LED lights flash to notify you of any abnormal operating conditions.
(They flash even when the button is not pressed)
Level Updates
If Tank Unit Mode Switch is set to 'test mode' – level updates every two seconds.
If Tank Unit Mode Switch is set to 'tank depth' – level updates 3-4 times an hour
(every 15-20 minutes).

Testing Range
1) Remove Tank Unit lid and set Mode Switch to test mode. Press Tank Unit reset button.
2) Reset Display Unit by holding down button for 3 seconds. The Display Unit will beep
every two seconds when in range of Tank Unit.
FAQ
How do I Improve the range?
The range is affected by trees, sheds, walls, buildings etc between the units.
Following are some suggestions for improving the range:
- Move the Display Unit closer to the Tank Unit
- Remove obstructions between Display Unit and Tank Unit.
(Trees will reduce range, especially when wet or covered in snow)
- Remote mount Tank Unit antenna in a better location using a 2.4m (8 foot) extension
cable. Aquatel Part: AQC4A. A higher location is better as the ground absorbs the
signal
- Replace Tank Unit antenna with a high gain directional antenna. Aiming at the Display
Unit will significantly increase the range (line of sight over 1000 meters, 3000 feet).
Note: Check your local regulations regarding using this type of antenna
(does not comply with EMC and may require a license).
Aquatel Part: AQ433 for 433 MHz (Australasia, Europe)
AQ920 for 920 MHz (USA, Asia)
Why is the Display Unit not displaying the correct liquid level?
- Ensure the angled cone on the Tank Unit is parallel to the fluid surface
- Ensure the Tank Unit depth has been set correctly. Adjust this by removing the Tank
Unit cover and changing the Mode Switch setting using the previous table.
If the Display Unit is showing empty but there is still water in the tank then increase
the tank depth setting.
If the tank is empty but the Display Unit is not yet showing empty then decrease the
tank depth setting.
- If this occurs during periods of rainfall it will be because the Tank Unit is mounted
right next to the inlet.
- The surface of the liquid has lots of bubbles (in a septic system)
- In tanks under 1500mm (5’) deep ensure Tank Unit is mounted in centre.
Any other questions please email [email protected]
Troubleshooting
If the Display Unit is not updating then:
- Reset the Display Unit. (Hold button down for three seconds until all LEDs light up)
- If problem persists reset the Tank Unit. (Take off Tank Unit lid and press reset button)
- If problem still persists check Display Unit is in range of Tank Unit
