V-line AdBlue

47xx.xxx

series dispensers (pressure design)

differ from suction dispensers because they

are not equipped with the pumping monoblock. A safety breaking valve shall be fitted in the connection.
The valve prevents AdBlue

leakage in case of the dispenser damage. This valve is not a part of the

dispenser, as well as the pump, which is located in the underground tank. The pressure dispensers are
equipped with an inlet spherical valve for closing the AdBlue

input in case of repairs.

The pumped AdBlue

is supplied from the central submerged pump located directly in the fuel storage tank

through the safety breaking valve, spherical check valve and the filter with filtering property of 60 µm.
Liquid is discharged from the filter through the meter and the electromagnetic valve to the dispensing hose
with the dispensing nozzle at its end. The dispensing nozzle lever controls the rate of flow.

The pressure system of the distribution should be designed with a submerged pump built-in directly into the
storage tank under the substance level. The tank should be equipped with a detector of the lowest
substance level switching the el. circuit of the pump motor being the min. level attained.
The location of the pump under the lowest fluid level in the storage tank and the min. level control switch
shall prevent the access of air or gas into the pump.
P12 = 0 parameter shall be preselected in the electronic counter for the pressure system of submerged
pumps operation in the storage tank in case of V-line AdBlue

47xx.xxx dispensers operation. At first the

electronic counter starts up the submerged pump in this mode of operation (the fluid in entire hydraulic
system is under pressure) then the counter tests the displays and closes the el. magnetic valve - and the
dispensing is started. Applying these conditions is the requirement 5.1.3 OIML R 117-1 2007 (E).

4.3.1

Filter

Whole metalic filter (pos.3) is connected by connection (pos. 4) to inlet of the meter (pos. 4) – to meter
flange (pos. 5) and closing stainless baal valve (pos. 1).
Filter is equipped by stainless filter insert with filtration ability 60 µm.

ATTENTION!

Filter is designed as meter protection from mechanical damage contained imide of dispensed
medium AdBlue

. Purity of dispensed medium AdBlue

must be guaranted by medium subsupplier

and permanent clean policy of storage space inside of storage container.

4.3.2

Piston flow meter

Measuring unit consists from four piston unit and integrated magnetic encoder. Measuring unit is measuring
in flow rate range 4 - 40 dm

.min

-1

and operational temperatures of measured medium - 10 až +30 °C and

ambient temperature -40°C to +55 °C for nominal pressure up to 0,32 MPa.
Encoder is reading spins of magnet disc connected to central shaft and transfering the spins to electronic
signal.

Meters are supplied with optional integrated magnetic pulse transmitter METRA MTX 076
or ADAST 41 - M 403.25AP/1, M 403.32EAP/1.
Meters with the designation of EP in electronic calibration, indicating P mechanical calibration.
