Chapter 1
Introducing MicroScan
MicroScan is an ultrasonic, non-contact level measurement
device of mono-block construction (combing the sensor and
electronic components in a single unit). MicroScan provides
reliable and precise level measurement results of both liquids
and solids.
It can be used for the following measurement tasks:
)Liquid tanks with calm surfaces
)Solids tanks that are dust-free
MicroScan has a range of up to 5 m (16.5 ft) with an
accuracy of approx. 0.25% within that range.
MicroScan is available in two configurations:
)MicroScan with no display and no keyboard ("Blind" unit)
)MicroScan with optional display but without keyboard
The following models are available for each configuration:
)MicroScan L for liquids
)MicroScan S for solids

Sensor Recommendations
Material Description
Stainless Steel For liquid applications.
High resistance in highly
acidic and alcoholic
environments.
Less sensitive to echoes (in
Solid applications).
Coated Aluminum Designed for complex
environments with
problematic echoes, such as
non-conductive vapors, solids
or liquids.
Good performance in
problematic applications.
High sensitivity to echoes.

Installing MicroScan
Precautions
)Ensure that MicroScan is mounted in an area that meets the
stated temperature, pressure and technical specifications.
)Ensure that high-voltage sources or cables are at least 1 m away
from the sensor and its cable.
)Use a conduit connector that is either 1/2" NPT or M20x2.5
compatible (depending on the MicroScan model you have), to
ensure the unit remains sealed.
)Use 26-16 AWG round wires for the MicroScan’s electrical
connections.
)Ensure that cables are routed correctly and tightened along walls
or pipes.
)Installation and operation of this product should be performed,
according to the Product User Manual and Product Certification,
otherwise the use of this product is prohibited.

Installing MicroScan
When installing MicroScan, ensure that it is:
)Mounted above the dead-zone area.
NOTE:
If the device enters the blocking distance (dead
zone), it will not measure correctly.
)Positioned at least 0.5 m (1.64 ft) away
from the tank walls.
)Perpendicular to the surface of the
target.
NOTE:
Even the slightest difference in angle may affect
echo quality.

)Placed as far as possible from noisy
areas, such as a filling inlet.
Installing MicroScan on Threaded
Flange/Thread-Free Flange
MicroScan is available in two thread types, 2" BSP or 2" NPT.
MicroScan can be installed with threaded-flange mounting or
with thread-free flange mounting, as shown below:
Figure 3: Threaded Flange/Thread-Free Flange Mounting

Installing MicroScan
CHAPTER 2
9
NOTES:
When installing a thread-free flange mounted unit, you will need a 2"
locking nut to secure the unit inside the tank.
When installing a threaded flange, ensure that it matches the MicroScan
threads.
¾To install MicroScan:
1Insert the threaded end of MicroScan into the aperture at
the top of the tank or pipe.
2Bolt MicroScan into place in one of the following ways:
)Threaded-flange mounting: Screw the unit into a
flange with a threaded 2" hole.
)Thread-free mounting: Place MicroScan in the flange,
and bolt it from within the tank with a 2" locking nut.
NOTES:
Tighten the nut by hand only. When tightening the nut, hold the
sensor housing (refrain from holding the MicroScan unit when
tightening the nut).Make sure that the seal is leak proof.

MicroScan User’s Manual

Installing MicroScan via Extension
Pipes
If the level of the measured surface falls within the dead-zone
area, you should use an extension pipe to mount MicroScan.
When using an extension pipe, ensure that:
)The sensor is positioned in the center of
the pipe.
)The pipe extension is parallel to the
side/tank walls.
)The internal pipe diameter is at least 3"
wide.
When installing the MicroScan with extension pipes, follow
these specifications:
Pipe Length Internal Pipe Diameter
0.50 m (1.64 ft) 3"
1 m (3.28 ft) 3"
NOTE:
It is always recommended to use interference signal feature (Pr.03)
to locate interfering signals when using an extension pipe.
It is highly recommended that the extension pipes material would
be PVC or Plastic and not Stainless Steel.

2Detach the front door from the MicroScan unit.
3Remove the rubber sealing from the conduit entry.
4Thread the power cable through the conduit entry.
5Remove the plastic shell from the power cable.
6Connect the +24VDC wire to Terminal 1, connect the
0VDC (GND) wire to Terminal 2 on the wiring block.
7Make sure that the terminals’ screws are properly fastened.
8Attach the front door to the MicroScan unit.
9Screw the four Allen screws to the plastic door.
Figure 4: MicroScan Power Connections
NOTE:
Make sure that the O-Ring of the MicroScan's front door is properly
positioned to maintain the unit sealed.

Connecting the MicroScan to the MSU
(MicroScan Setup Unit)
The MSU is an hand held device which enables you to
configure the MicroScan unit according to your application
requirements, quickly and simply. Once the MicroScan unit
configuration is completed, the MSU can be utilized to
configure other MicroScan units.
The MSU should be connected to the MicroScan unit after
connecting the unit to a power supply.
1Remove the plastic cap from the MSU connector located
on the MicroScan unit (the cap is chained to the
MicroScan unit).
2Remove the plastic cover from the MSU multi-pin
connector.
3Attach the MSU male connector to the female connector
on the MicroScan unit, located on its left side panel.
4Make sure that the connectors are in the right position
and properly attached.
5Rotate the plastic clasp on the MSU connector, half way
to the right, to ensure the connectors are firmly closed.
