This
type of removable woltman
water meter is specially manufactured
with dynamically balance turbine
to be sensitive for wider
range of flow rates. This
water meter can be equip with
IP68 and install with an option
for radio frequency type register.

Accurate
measurement of water
volume passing through
the pipeline.
Capable
for inductive meter
reading technology
with robust wireless
data transmission.

GENERAL
DESCRIPTION OF PATTERN
The
Removable Woltman
Water Meter are
meant for the metering
of water and classified
under accuracy Class
2.
The
principle of this
meter are operated
based on the Flow
Velocity of water
detected by impeller
which can laterally
move along impellers
axis in the flow
direction.
The
water meter consists
of ductile iron
body, exchangeable
measuring units
with impeller, and
indicating device
complete with gearing
system.
This
water meter are
not design to measure
reverse flow.
The
water meter can
be install and operate
in arbitrary position.
FEATURES
The
water meter can be install
and operate in arbitrary position.
This
water meter have a wider flow
range especially with lower
minimum flow rate.
Capable
of having exchangeable measuring
range i.e. R160 to R400
The
register can be rotated in
any position.
Inter-exchangeable parts.
The
meter require 10 diameter
and 5 diameter length for
inlet and outlet respectively.
High sensitivity at lower
flow rate.
MEASURING PRINCIPLE : FLOW
VELOCITY USING IMPELLER
The
working principle is based
on impeller that rotates and
moved laterally along the
axis in the flow direction.
The movement of this impeller
along the axis is hydrostatic
depends on the flow rate.
The impeller will move forward
along the axis in high flow
rate but return back to original
position under lower flow
rate.
The
rotation of the impeller is
attached to a worm gear which
is connected by shaft to indicating
device. Using a permanent
magnets on shaft and indicating
device, the rotation of impeller
is transfer to indicating
device to denote the total
volume of water passing through
the water meter.
