TATSUNO EUROPE FUEL DISPENSERS
1.1.
DESCRIPTION OF DISPENSERS
All TATSUNO EUROPE dispensers are equipped with high quality technology 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).
The compressed natural gas (CNG) dispenser or dispensing module
has a pressure part fitted with
certified components made of stainless steel or galvanized steel. The access to the CNG pressure system
is fitted with a lever‐closable ball valve, then 25µm input particle filters to protect pressure component
and equipment. Gas filling is regulated by valves and secured with check valves. The amount of gas flown
through is measured with a mass meter the input of which is fitted with an electronic pressure sensor and
mechanical pressure gauge (manometer). All such pressure connections are performed by using stainless
or galvanized steel pipes with a high‐quality connection system (two rings). All fixtures and brackets in the
pressure section are made of galvanized sheet metal. The output of the pressure module and fixture of
delivery hoses is secured with a fixed connection to which a delivery hose is connected which is fitted with
a safety breakaway coupling that shuts the gas flow through the delivery hose on both sides in forcible
tension stress with following disconnection. The delivery hose ends with a delivery nozzle. The pressure
section of the CNG dispenser may be further equipped with a heat sensor for measuring the ambient
temperature. Installation of the heat sensor allows activation of the filling temperature compensation
function Filling with temperature compensation ensures that the vehicle storage tank is always filled with
a maximum amount of gas while observing the condition of maximum pressure in the tank of 20 MPa at
15 °C – see TPG 304 02 art. 4.5.4.
