5.4.6. Function of system VRC with VRMS
Function of system VRC-M with VRMS
Function of system VRC-M
The vacuum in the VRC-M system is created plunger vacuum pump (Item 2), which is powered via a
rubber belt electric pumping monoblock. For dispensers with pressure system is installed in a compact
unit with integrated electric pump.
Outgoing gasoline vapors from the tank car when dispensing gasoline are drawn special adapter nozzle
(item 7), through the channel in the body to control flow through the gun hydromechanical valve
integrated into nozzle and into the inner coaxial hose DN 8 (Item 6). The coaxial spacer (Item 5) pairs
are fed to a flexible connecting pipe (Item 4), then proceed to the measurement sensor VAPORIX-Flow
(poz.9) and then connecting flexible pipe (Item 3) to the piston pump (pos. 2). The piston pump (item 2)
are pushed through a flexible pipe (Item 1) into the duct connected to the vapor inside the storage tank
(usually from the lowest octane gasoline).
Optimal flow of vapor is dynamically regulated proportional hydromechanical valve depending on the
actual flow of liquid gasoline nozzle.
Proper function of vapor recovery is indicated by shining symbol of two arrows (Fig. 9) on the display of
electronic counter on the appropriate side of the dispenser.

Function of system VRMS:
Automatic Monitoring System (VRMS) VAPORIX dynamically controls the system to function properly VRC.
Measuring sensor VAPORIX-Flow (Item 9) indicates the instantaneous flow and vapor flow rates found
online transmitted to the evaluation unit VAPORIX-Control (Item 10), which compares these values with
the values given volume of liquid gasoline from the transmitted pulse output electronic counter (Item 8)
into the VAPORIX-Control - Connection Figure 6 (Item 4).
The operational statue of the system can notify the operator VRMS at the kiosk station via electronic
unit VAPORIX-Master, which is usually located near the pumping station control system - POS.
VAPORIX-Control Units and VAPORIX-Master are communicatively connected via RS 485 interface
using a communication cable.
Function of system VRC-E with VRMS
Function of system VRC-E
The vacuum in the system VRC-E is generated plunger vacuum pump (Item 2), which is powered via a
rubber belt electric pumping monoblock. For dispensers with pressure system is installed in a compact
unit with integrated electric vacuum pump.
Outgoing
gasoline vapors from the tank car when dispensing gasoline are drawn special adapter nozzle
(Item 9), through the channel in the gun body flowing into the inner coaxial hose DN 8 (Item 8),
attached to the coaxial spacer (item 7). The coaxial spacer (item 7) are fed to the steam flexible
connecting pipe (Item 6), then proceed to the measurement sensor VAPORIX-Flow (poz.11) and then
connecting flexible pipe (item 5) to control the proportional solenoid valve. The valve is kept flexible
pipe (Item 3) to the piston pump (Item 2). The piston pump (item 2) are pushed through a flexible pipe
