Fuel Dispensers TATSUNO EUROPE ‐ Installation and User Manual , revision 10, January 2022
2. TATSUNO EUROPE DISPENSERS
2.1. DESCRIPTION OF DISPENSERS
All TATSUNO EUROPE dispensers are equipped with high quality Japanese hydraulics from TATSUNO
Corporation (hereinafter referred to as TATSUNO) and a powerful reliable electronic counter of the Czech
company TATSUNO EUROPE (hereinafter referred to as TE). All dispensers work in the manual mode –
independently, offline – as well as the automated mode, when they are controlled remotely from the kiosk of a
fuel station and connected to the cash register (POS) via a data line. All dispensers have body parts (covers,
doors, lids, etc.) made of steel painted sheet metal or stainless‐steel sheet metal. Supporting parts of dispenser
frames are made of steel painted sheet metal of a thickness 0.8 to 2.5 mm, or stainless‐steel sheet metal. Each
dispenser is equipped with an electronic counter with its own diagnostics and displays showing the delivered
amount of money in the currency of the country of installation, the amount of fuel in litres or kilograms and the
fuel unit price. Displays of the fuel dispensers specified for private use display only the dispensed fuel volume in
litres. The standard colour of TATSUNO EUROPE dispensers is white (RAL9016), silver (RAL 9006) and black
(RAL9005).
NOTICE
Standard painted versions of TATSUNO EUROPE dispensers are not intended for use in high humidity,
chemical and saltwater areas. For such applications TATSUNO EUROPE supplies options using stainless steel
materials.
Dispensers and modules for dispensing gasoline, diesel, biodiesel, E85, kerosene, light fuel oils and aircraft
fuel are equipped with hydraulic (pumping monoblock, piston meter, pulse generator ... etc.) from a Japanese
company TATSUNO Corporation. This is a time‐tested and worldwide accredited type of hydraulics with a high
reliability and a long service life. The pumping monoblock is equipped with an input and output washable
stainless‐steel filter (100μm/70μm), vapour and gas separator, check valve and rotary pump with operating
pressure control. The four‐piston high precision meter can be controlled by a single piston. Each flow meter
contains a non‐explosive pulse generator (pulser) that senses the meter shaft speed and sends impulses to the
electronic counter. The delivery hoses are made of high‐quality gas‐resistant rubber in an antistatic design and
are finished with automatic delivery stop‐nozzles. The delivered medium (gasoline, diesel ...) is sucked out of
the fuel storage tank by the dispenser and passes through the flexible connection bellows and the check valve
into the pumping monoblock where it is filtered and the air is separated. The separated air is freely discharged
from the pump into the hydraulic part of the dispenser. Clean fuel flows from the monoblock by a check valve
to the piston meter and from there through a solenoid valve controlling the fuel flow into the delivery hose and
through the delivery nozzle it is transported to the vehicle storage tank. In the case of pumping diesel, biodiesel
and mixed diesel, a sensor measuring the flow of the separated air is at the output of the monobloc separator.
In case of a high amount of air in the fuel (cracked piping, lack of fuel in the tank ... etc.) the sensor activates and
causes the delivery to stop. In the case of gasoline and ethanol (E85) delivery, the hydraulic module of the
dispenser is supplemented with a gasoline vapour recovery system consisting of a pump, pipe and control valve.
Gasoline vapour is sucked out of the vehicle tank by a vacuum pump and transported through the DN8 pipeline
out of the dispenser into the return pipe into the fuel storage tank. The exhausted vapour flow is regulated in
the dispenser to match the fuel flow rate (95% to 105%).
