Overview
MiniWave is a compact, loop-powered ultrasonic level transmitter for continuous measurement of liquids. As
a price leader, it does not compromise on good value; and provides effortless and intuitive operation. Easy
and flexible mounting combined with high chemical compatibility and 12-metre measuring range makes the
MiniWave suitable in multiple applications in all industries.
Principle of Operation
The MiniWave emits an ultrasonic pulse, which is reflected from the surface of the liquid being measured. The
reflected signal is processed using specially developed software to enhance the correct signal and reject false
echoes.
Automatic sensitivity control allows the unit to dynamically adjust and improve the received echoes for the best
possible measurement outcome.

Mounting
• Sensor should be mounted 1/3 the diameter of the
vessel from the vessel wall
• Unit should never be closer than 250mm (10") to the
liquid surface
• Do not mount over or near objects which can interfere
with the unit measurement
• Do not mount in the centre of a curved roof to avoid
the potential of parabolic echoes
• Ensure appropriate UV protection.

Powering The Unit
When power is applied, the unit will start up automatically. The LCD will scroll through its boot diagnostics and
display the serial numbers, software version and model types for the amplifier and transducer.
The selected Display Mode will be visible with a measurement.
The top right hand corner diagnostic indicates either the operating mode or the current output.
The unit will re-scan for the level whenever it is powered up.

Troubleshooting
MiniWave User Manual

Unit is displaying incorrect distance
• Confirm display mode is suitable.
Space is measured from Sensor face to measured level.
Material is measured from Low Level to measured level.
• If unit is measuring too deep increase Sensitivity.
If the unit continues to measure too deep, increase
WaveBoost
• If unit is measuring too high, reduce Sensitivity and
ensure WaveBoost is set to 0.
• Check if material is present to be measured. Unit
will output and display FailSafe reading if it cannot
detect a level within range.
PLC indication does not match measurement
• Connect a Multimeter in series with the powered
loop. Compare the 'mA' diagnostic on the display
with the mA reading on the loop. If these values do
not match, disconnect the loop wires and measure
the resistance across the loop. This should not
exceed specification.
• Confirm High Level and Low Level are set to the
same values in MiniWave and control system.
Analogue trend is erratic/unstable
• Increase 'Damping' value for smoother trends.
• Choose a slower 'Tracking' speed.
• Check there are no objects interfering with the
transit pulse in the application (such as ladders and
cross beams).
Unitislockeduporatlinemeasurement
• Confirm there is material within measurement
range, the unit may go to Failsafe if there is no flat
level available.
• If the unit is locked to a high level perform Mapping
for distance beyond false echoes.
• If the unit is locked higher than the real level check
for objects interfering with the transit pulse in the
application (such as ladders and cross beams).
Lower the Sensitivity/WaveBoost. Re-locate the
installation to avoid the interfering object.
• If the unit is locked lower than the real level confirm
the application is not within Blanking distance.
Increase Sensitivity/WaveBoost until unit
measures correct level.
• Tracking speed may be too slow for the application.
Increase Tracking speed.
AutoSet fails
• Increase 'Sensitivity' to a higher value.
• Allow the unit to run for a longer time (one minute).
Re-attempt the AutoSet.
• Increase WaveBoost and re-attempt the AutoSet.
• Set High and Low level manually in 'Setup' menu.
If problems persist, install replacement
MiniWave in the application.
'Bench test' the problem unit in a controlled
environment.
Difficult applications may be required a low
frequency Acoustic Wave device. Contact
HAWK for information about the Sultan series.

Hawk Measurement Systems Pty Ltd (HAWK) was
established in 1988. It's founding members saw the
universal requirement of various industries requiring
improved process control and efficiency in their
operations.
We Can Help
HAWK understands the difficulties customers face
when seeking accurate level measurement. Every
application is different, involving a multitude of
environmental factors. This is where HAWK excels.
Our aim is to ensure that customers feel comfortable
with our technology, and are provided with long term
and reliable solutions. We believe that a combination
of application and product expertise, as well as
forward thinking and proactive support policies
are the foundation of successful customer-supplier
relationships.
Progressive Technical Support
HAWK believes that the future of the Level
Measurement Industry revolves around the quality of
pre and post sales - support. Our aim is for all sales &
support staff to be product experts, and more
importantly application experts making our customers
applications asefficient and consistent aspossible.
Remote Innovation
HAWK understands the need for immediate technical
assistance.
