Product description
EN
Unitop
4 Product description
The product measures the hydrostatic pressure at the tank bottom to deter-
mine the level. The hydrostatic pressure depends on the level and the density
of the stored liquid. The pressure is measured approximately 20 mm above
the tank bottom and indicated on the dial.
Pneumatic pressure is generated in the pressure line by pulling out and push-
ing back the pump plunger. The pressure line consists of the measuring line
(from the measuring instrument to the tank) and the vertical line (inside the
tank). The pneumatic pressure displaces the liquid from the vertical line.
When the pneumatic pressure is equal to the hydrostatic pressure acting at
the tank bottom, the liquid is fully displaced from the vertical line. Bubbles
start to escape at the lower end of the vertical line. In this condition, the
pointer has reached the maximum deflection and remains at the indicated
value.
The product enables consumption monitoring and timely re-fuelling. The tank
lorry driver can use the product to verify prior to filling whether the ordered
volume fits into the tank.
It is recommended to use the mounting kit Pneumofix type 2, see chapter
"Spare parts and accessories".

Verify that the housing is accessible and easy to oversee at all times.
Verify that the housing is protected against water and splash water.
Verify that the housing is not mounted in a humid room.
Verify that the ambient temperature is not exceeded at the housing.
Verify that the housing is protected from direct sunlight.
1. Drill two holes at the same height at a distance of 13 cm.
- Use the enclosed drilling template.
2. Insert the enclosed dowels.
3. Screw in the screws up to approx. 1.5 cm.
4. Fit the product onto the screws and slightly pull it down.
- The lug is flush with the wall.
5. Fasten the product to the wall by means of the third screw.
5.2 Adjusting the measuring range and calibrating the zero point
The measuring range and the zero point must be accurately adjusted for the
product to operate with maximum measuring accuracy.
Verify that the measuring
line has not yet been con-
nected or open the vent
cap (A). The system must
be unpressurised.

5.3 Mounting the line
If no connection thread is available on the tank, several lines can be con-
nected via the combination fitting "Euroflex 3" to a single G1 connection
thread.
1. Mount the vertical line in the tank in such a way that the lower end of the
vertical line is approximately 20 mm above the lowest point of the tank bot-
tom.
2. Install the measuring line with a steady gradient towards the tank, avoid
bends.
3. Push the screw connection onto the measuring line.

Operation
EN
Unitop
6 Operation
Precise measurements are not possible during filling of the tank. The
pointer does not provide a stable reading during filling.
Verify that the vent cap is closed.
The product provides semi-permanent indication. The pump closes off the
measuring line when it reaches the upper dead end. The pointer stays tem-
porarily at its last reading and then drops back very slowly. As a result of this,
the gauge mechanism is protected by an air cushion.
1. Pull out the pump plunger all the way to the stop.
2. Then release the pump plunger.
3. Repeat the pumping procedure until the indicated value no longer
changes.
4. Read the level on the scale.
- If the measuring line has been installed airtight, the pointer of the gauge
will continue to show the last reading for a long period of time. In order
to obtain an accurate reading, always operate the pump before a read-
ing is taken.
The red reference pointer can be adjusted manually, for example to the level
after the last filling. The red reference pointer lets you compare the current
level to a previous level for consumption monitoring. The date indicator can
be adjusted manually, for example, in order to mark the date of the most
recent tank filling.
6.1 Setting the day
1. Push the adjustment pin to the top and turn it.
6.2 Setting the month
1. Push the adjustment pin down and turn it.
6.3 Use in flood hazard areas
The product is suitable for use in flood hazard areas; it is watertight up to 10
m water column (1 bar pressure).
The product does not have to be replaced after a flood.
