The dispenser has a powder painted, robust, steel  frame structure; the frame of the base is additionally zinc galvanized..

HYDRAULIC PARTS

4 cylinder piston flowmeter : spheroidal iron body, stainless steel cylinder sleeves, components made of high-alloy steel, equipped with a magnetic clutch to ensure gentle transfer of torque to the pulse generator when there is a "jerky” flow of gas; error adjustment with just one adjustment screw.

Gas phase separator : 2 dm³ steel container, flange mounted directly on the flowmeter.

Dragon's hydraulic filter with a stainless steel basket and magnetic cartridge stops all contamination with particles larger than 0.2mm.

Its differential valve protects against gas leaks during the filling process, reduces hydraulic impact forces present at the beginning and end of the filling process.

Aluminium visual inspection unit enables the user to check the fuel being dispensed and is used for diagnosing incorrect operation of the dispenser.

Filling hoses (short and long) DN16 with a usable length of about 5 m; the technical and operating documentation of the dispenser includes hose strength test certificates.

Italian Brevetti Nettuno standard filling gun .

  DN20 ball valves in the gas and liquid phase sections enable easy connection of  ¾"NPT breakable couplings.


 
FEATURES ENSURING SAFETY AND EASY OPERATION.
 

Breakaway coupling mounted on the filling hose protects the hydraulic installation of the gas meter and the car from the consequences of an accidental drive-off when a customer leaves the gun in the tank.

Liquid phase manometer shows LPG pressure in the hydraulic system; excessive pressure (for example in summertime, above 16 bar) will signal malfunctions in some parts of the dispenser.

Test port enables the user to carry out a series of useful operations; details can be found in the technical and operating documentation of the dispenser.

Relay output controling the operation of the LPG station pump.

 
WELMA TW1 ELECTRONIC CALCULATOR UNIT
 

WELMA TW1 is a well-known and reliable Italian made calculator unit.

The WELMA TW1 calculator unit can be operated both under the control of a computer system and in manual mode without control.

Two types of illuminated displays can be connected to the calculator unit

  • CSD-L : liquid crystal display
  • CSD-B: liquid crystal display (back-light version)
 

The standard version offers preselection functions. Preselection settings can be changed using a keyboard (volume and payment amount). The calculator unit offers totallizer functions with information being stored in the unit's memory separately for operation in the computer system mode and without the system controlling the operation of the dispenser.
The dispenser is also equipped with an electrical-mechanical totalizer for measuring the amount of fuel dispensed.

The WELMA TW1 calculator unit offers two transmission protocols:

 
LOGITRON IFSF
 

The standard version of the WELMA TW1 calculator unit uses the LOGITRON transmission protocol, which is the most popular in Poland. It can be connected through three controllers to many cash register systems:

 

POWER CABLES

  • 1 cable 5 x 1.50 mm 2 YbKSY power supply for the electronic counter and for controlling the operation of the pump;
  • 1 cable 8 x 0.75 mm 2 YbStYek¿ for communication with a cash register or controller.
