2 Safety
2.1 Intended use
Unimes E is only suitable for continuous level measurement in tanks
containing fuel oil EL, diesel and other low-viscosity media which do
not attack the materials used (refer to chapter 4, page 9). For tank
heights from 900 to 2000 mm.
Any use other than the application explicitly permitted in this instruc-
tion manual is not permitted.
2.2 Predictable incorrect application
Unimes E must never be used in the following cases:
• Hazardous areas (ex)
• Applications involving persons and animals
2.3 Safe handling
Unimes E represents state-of-the-art technology and is made ac-
cording to the pertinent safety regulations. Each device is subjected
to a function and safety test prior to shipping.
 Operate Unimes E only when it is in perfect condition. Always
observe the operating instructions, all pertinent local and na-
tional directives and guidelines as well as the applicable safety
regulations and directives concerning the prevention of acci-
dents.
 Unimes E is not safety equipment. It does not replace the func-
tion of a level sensor at the fuel oil tank.
 Unimes E may only be installed in unpressurised tanks. An ap-
proved tank vent and a fully functional level sensor must be in-
stalled.
 The measured values displayed, in particular the values of the
litre indication, must not be used for billing purposes. The accu-
racy of the measured values displayed depends on the accu-
racy of the tank data determined and entered. Therefore, the
accuracy required for billing purposes cannot be guaranteed by
the manufacturer.
Extreme environmental conditions have negative effects on the func-
tion of the product.
 Protect the product from shocks.
 Only use the product in rooms.
 Protect the product from humidity.

3.2 Function
The direct indication gauge is a universal mechanical tank contents
gauge. It features a fully adjustable brass and nickel silver gear train
mechanism. The pointer movement is always 270° when the tank is
full. The level is indicated in percentage of height. An electronic sen-
sor is located at the movement. It supplies the remote indicator with
a signal that is proportional to the level.
The remote indicator is connected to the mechanical gauge by
means of a 3-core screened cable and plug. The remote indicator is
operated by means of a long-lasting battery. It is only switched on to
read the level (push-to-read function). Diverse tank shapes are
stored in a microprocessor so that the level is indicated either in liq-
uid level or volume, as desired.
This combination of devices allows you to check the supply directly
next to the tank and from an easily accessible, different location.
The measurement signal is transmitted to the remote indicator via
the cable. Using this signal, the electronic system of the remote indi-
cator calculates the tank contents which can be displayed in litres,
cubic metres, percentage or liquid level. The display mode is se-
lected by means of function key F. The two programming keys 
and are used to enter the tank data.

6.2 Mounting the wall bracket for the remote indicator
 Mount the wall bracket to the wall where you want to position
the remote indicator using the enclosed screw (4 x 30 mm) and
a dowel, if required (6 mm).
6.3 Adjusting the float

A free connection G1½ or G2 is available at the tank.
The float wire has three lead seals. Lead seal 1 is located at the end,
lead seal 2 is located 15 cm higher. The moving lead seal 3 is lo-
cated between these two lead seals.
1 Lead seal 1: fixated
2 Lead seal 2: fixated
3 Lead seal 3: moving
Fig. 2: Float wire
Tank without manhole or flange connection piece
 Push the float up to lead seal 2 and press lead seal 3 together
to fixate the float.
Tank with manhole or flange connection piece
1. Deduct the excess length of the manhole or the flange connec-
tion piece with reference top the wire length from probe 2 to-
wards probe 1.
2. Mark the point, push the float up to the mark and press lead
seal 3 together to fixate the float
6.4 Adjusting the tank height at the direct indication gauge
