KRAL Volumeter®.
Decide for the
original.
Our flowmeters combine
the otherwise mutually
exclusive properties of
robustness and precision.
For 25 years, our products
have satisfied a wide range
of customer requirements.
These qualities
provide
extra security in the decision
making process.
The measuring principle.
The KRA L Volumeter is a
very compact positivedisplacement
meter. The
measurement chamber
consists of the casing
and two screw spindles.
The spindles continually
divide the liquid in a
precision made closed
measuring-
chamber –
nothing escapes. The
precise measured value is
calculated
from the known
measuring-
chambervolume
and the spindle
rotation speed.
Measurement accuracy.
The precision of the measurement
is unmatched:
The KRA L Volumeter is
accurate to ± 0,1% of
rate over a wide flow
and viscosity
range. The
reproducibility
is better
than ± 0,01%. The long
working
life and stability
over time show that robustness
and precision
are not mutually exclusive.
Silent operation.
Other flowmeter technologies
can produce noise
levels as high as 100 dBA,
requiring ear protection
for operating personnel.
In comparison the KRA L
Volumeter is scarcely
audible.
Liquids and areas of
application.
KRA L Volumeter measures
the flow of liquids. KRA L
is the first choice when it
comes to measuring anything
from low-viscosity
liquids like petrol, acids
and alkalis to high-viscosity
liquids such as printing
inks and bitumen. Our
measuring equipment is
found in many industrial
areas such as:
Marine.
Energy.
Fuel engineering.
Hydraulics.
Test stands.
Mixing and batching
technology.
Chemical industry.
Food industry.
Understandable measuring
technology.
The measurement values
are calculated understandable
and accurate. The
liquid flow drives the spindles.
Poles on the wheel
generate impulses in the
sensor. Each pulse from
the sensor represents a
precisly calibrated volume.
