Hawk
Measurement Systems Pty Ltd
(Hawk) was established in 1988
following the recognition by
directors of the potential of
ultrasonics and the application
to level and flow process
equipment. The company developed
its own product range through
its research and development
program. The product range
consists of the range master
series, microwave level
controls, loop power controls,
flowmaster admittance switches,
sludge level systems, portable
sludge meters and submersible
pressure instruments

The SULTAN 234
emits a high
powered acoustic
wave transmit
pulse which is
reflected from
the surface of
the material
being measured.
The reflected
signal is
processed using
specially
developed
software to
enhance the
correct signal
and reject false
or spurious
echoes. The
transmission of
these high
powered waves
ensures minimal
losses through
the environment
where the sensor
is located. Due
to this high
powered emitted
pulse, any
losses have a
far less effect
than traditional
ultrasonic
devices. More
energy is
transmitted
hence more
energy is
returned. The
receiver
circuitry is
designed to
indentify and
monitor low
level return
signals even
when noise
levels are quite
high. The
measured signal
is temperature
compensated to
provide maximum
accuracy to the
outputs and
display. |

The ORCA series
Sonar will
measure up to
two density
interfaces
simultaneously,
either bed level
or RAS blanket
and floc/fluff
layer or clarity
of water, using
the new ORCA
Sonar hardware. |

Any application
where microwave
energy is
absorbed by the
material being
monitored,
including
replacement of
traditional
contact
switching
devices used in
mining, sand and
gravel quarries,
cement plants,
pulp paper,
plastic, rubber,
coal fired power
plants, steel
mills, aluminium
smelters, food,
pharmaceuticals
and other
manufacturing
fields. |
