Description
Modular design
VOLUMEC Indicator
AVC .. A Optically
AVC .. B Open/close switches
AVC .. C/CL Potentiometer
AVC .. D/DL Open/close switches and potentiometer
AVC .. E/EL Potentiometer with delay
The Valve Position Indicator VOLUMEC is a combination
unit with mounting surface for directional control valves
NG 06 according to ISO 4401-03-02-0-02/DIN 24340-A6.
In detail the module consists of a hydraulic manifold,
a gear type volume counter and an indicator.
Mounted on a connection plate and completed by a
directional control valve the VOLUMEC enables to
control hydraulic operating ship armatures for
ballast-, cargo- and stripping systems of all kind of
tankers. In addition to that the adjusting path of the
armature will be measured and displayed.
The Valve Position Indicator is suitable for the installa-
tion into deck boxes. The indication of the volumetric
entered armature position can be read
off optically locally or can be taken electrically by
potentiometers or open / closed switches.

VOLUMEC Indicator AVC 02
Function
Together with the gear type volume counter the
indicator builds the measuring unit. The turning of the
gear wheels is transferred via a magnetic drive to the
gear box of the indicator. For each application the
turndown ratio of the gear box is configurated to get
a pointer movement of approx. 180 °. The pointer is
limited by two end stops. To reset the indication at
each end position a slipping clutch is integrated.
The driving shaft of the magnetic drive is equipped
with a small indication to recognize the movement of
the gear wheels. It can be used as leakage detection.
The indicator is completely separated from the
hydraulic circuit. The housing of the indicator consists
of seawater resistant aluminium, all fixing materials
are made of A2.
