MG-80 · MG-80V DESIGN FACTORS
The MG-80 meter is for private use.
The 1" GAS (BSP) Female Inlet and Outlet Threads take part of the housing. It has 3 inlets. They can be seen from the back: frontal, left lateral
and bottom. It also has 2 outlets. They can be seen from the back: right side and top.
The meter is delivered with horizontal inlet and outlet. Nevertheless, the user can change their position in a short time; the plugs of the desired
direction must be taken out and put them on the non-desired direction. The inner threads have joints which guarantee the sealing; you must only
tighten until its locking, giving up pastes, liquids and sealing products.
The MG-80 volumetric mechanical meters have two numerations (registers):
- The partial with three big numbers where it is possible to read up to 999 litres. It can be reset through a lateral wheel after each supply.
- The 6-digit totalizer with capacity up to 999,999 litres; after that and with its operation, it is automatically reset, starting the cycle again.
MGI-80 · MGI-80V FEATURES
The MGI-80 · MGI-80V pulsers are different from the MG-80 meter. They have a pulser in its inner of 2 communication channels where the con-
nection to a consumption controller is allowed. It also has a lateral packing gland and 90 cm of connection cable.
There is a cable of five little wires from the encoder:
Brown colour with 6-24 V feeding, white 0 V, A (or 1) green channel, B (or 2) yellow channel, and Z (or 3) grey channel.
The encoder generates 10 pulses per channel and supplied litre.
Please read all the instructions carefully before using the product. The people who do not know the instructions must not use it.
This manual describes how to use the mechanical meter according to the project hypothesis, the technical features, the types of installation, the
use, the maintenance and the training regarding to possible dangers.
The operation manual must be considered as a part of the mechanical meter and keep it for future inquiries during all its working life.
We suggest keeping it in a dry and protected place.
The manual reflects the technical situation in the meter sale and cannot be considered inadequate for the reason of being updated according to
the new experiences. The manufacturer reserves the right to update the production and the manuals without being forced to update the production
and previous manuals.
The meter security, regarding to the equipment quality and reliability, is determined by the EC Directive Regulations and endorsed by the quality
controls of the enterprise leaders in the sector. It also guarantees the toxicity absence and the negative ecological effects. To avoid the possible
accidents, it is advisable to read the following warnings and cautions carefully:

2. WARNINGS
3. SECURITY INSTRUCTIONS
3.2. Do not smoke when the flammable fluids, hydrocarbons, are transferred. A FIRE CAN BE CAUSED.

3.3. This meter has been designed for the hydrocarbon measurement, but with some restrictions regarding to its use with
certain liquids.
The compatibility list is the following one:
• MG-80 is suitable for diesel.
• MG-80V is suitable for diesel, petrol and aviation fuels.
• MGI-80 and MGI-80V are suitable for diesel.
The meters are precalibrated in the factory. IT IS ADVISABLE TO CALIBRATE THEM ONCE THEY HAVE BEEN INSTALLED.
Each liquid type has its own density and viscosity. In order to get a reliable measurement, it is advisable to make this calibration with an approved
test tube or decalitre. It can be used a container, whose capacity you should know previously.
Calibration procedure
6.1. For an exact calibration, the meter, the hose, the nozzle and the pump must be full of liquid, but free of air. This is achieved emptying from 10
to 20 litres of liquid and closing the nozzle, without stopping the pump until the operation is finished.
6.2. Fill the approved decalitre until the exact measurement (10 or 20 litres). The bigger the recipient is, the better accuracy you will have.
6.3. If the quantity does not correspond to the emptied liquid in the recipient, it needs to be calibrated.
The meters are very easy to install. Then it is specified the appropriate process to make the installation more comfortable, using the six possible
combinations to the pipe and hose assembly.
4.1. Check the most right fluid direction. It is not necessary to disassemble the meter to change the liquid direction.
4.2. Take out the chosen inlet and outlet hole plugs, as well as their joints.
4.3. Put these joints and plugs in the holes that are not going to be used. It is not necessary to put other joints in the threads. Everything is foreseen
to get a total sealing. The thread end has a nitrilic joint (or Viton joint according to the model) which guarantees the total sealing with a minimum
pressure.
4.4. It is necessary to use sealing components on the installation pipes and threads, which are resistant to the products to transfer.
3.4. Make sure of the correct installation of the decanting circuit, checking the leak absence.
3.5. It is advisable the assembly of a check valve in the meter outlet. So, it is avoided some problems on the pumping and measuring equipment,
for instance because of an accidental tread on the delivery hose.
It is not advisable to disassemble the meter, but if you are going to do this, take into account the meter has a measuring chamber with liquid
distributor holes, a partial and a total numeration register. Please see the explosion view section. The meter is divided into parts so that it is easier
to identify each part. Please use the corresponding code number when asking for it, and take into account the meter can be taken into pieces
without disassembling the pipes.
5.1. Take out the lateral reset drive (16).
5.2. Take out the rubber nut cap (12).
5.3. Slacken the two screws (21) and remove the unit numerator cover (19).
5.4. Unscrew the screws (17) that subject the numeration (22) and take it out carefully.
5.5. Unscrew the 8 screws (15) of the central cover (14) from the housing fixation supports (7). When the central meter cover (14) is opened, be
careful because there are the measuring chamber mechanism gears in its inner.
5.6. For its assembly, follow the above described steps in the reverse order, taking into account the correct installation of the housing fixation
supports (7), Viton joint (9) and the special square Viton joint (13).
6.4. First, take out the plug (4) and turn the screw (6) clockwise. Then, the flow percentage decreases. Turning it anticlockwise, it increases. A
complete turn varies the measurement, more or less in 0.4 litres each 10 litres.
6.5. If you want to guarantee a correct calibration, you have to repeat the above step three or four times. If the result is correct, a good adjustment
will be achieved , and the meter will be ready to be used. Do not exceed the pressure of 3.5 bar, and do not work less than 1 bar.
6.6. The MG-80 meter can work by gravity or with a pump. Remember the suitable minimum pressure is 1 bar with a minimum flow of 15 l/min,
and an accuracy of ±1%. If you use it by gravity, it is possible there is some mistake in the measurement due to the different liquid height that the
tank may have. It is always advisable to install a pump.
3.6. IMPORTANT
The meter has a high accuracy because of the minimum tolerances there are in its measuring chamber. It is one of the most
exact meters in the market.
IT IS OBLIGATORY TO INSTALL THE RED ADAPTER WITH FILTER of 350 µm (micron) or the PLASTIC FLANGE KIT WITH FILTER of
350 µm (micron) in the inlet used by the meter in order to avoid the measuring chamber is blocked because of the solid impurities.
IT IS ALSO ADVISABLE to INSTALL the FG-100 MICROFILTER in the pump suction if you want to get a better microfiltration.
4. INSTALLATION
5. DISASSEMBLE-ASSEMBLE
6. CALIBRATION
The calibration process must be done with the nozzle totally open. Never calibrate it with the nozzle mid-opened.
7. MAINTENANCE
The MG-80 meters do not need maintenance. It is possible that some liquids are dried up on the measuring chamber inner, causing an obstruction.
If this happens, they must be cleaned with a lot of care, and when they are going to be mounted, ensure it is correctly done.
If hydrocarbons are used, they can be cleaned with cleaning liquids or oil. Follow the instructions from section 5. Disassemble-Assemble. When
the MG-80 meter is stored for a long time, clean it conscientiously. It will remain protected and ready for a new starting.
WHEN USING THE METER FOR THE ADBLUE/DEF TRANSFER
Due to its chemical composition, the AdBlue/DEF is easily solidified making crystals when it is in touch with the air. These crystals may block the
different mobile parts of the meter. To avoid this characteristic affects to the kit operation, please take into account the following:
If the meter is stopped some days without working, flow demineralized water (preferentially in hot) many times so that the AdBlue/DEF rests are
eliminated and avoid these crystallize in its inner.

8. REPAIR
The authorized repair workshops are the only ones which can repair the motor in bad state. The meters must be cleaned and dried up before its
delivery to be repaired.
When ordering spare parts, make sure it is given the correct code of the spare part, the manufacturing date and the pump serial number. This will
guarantee the correct supply of the requested spare part.
