Introduction
The Probe is an ultrasonic level monitor combining sensor and electronics in a single package. It is
designed to measure liquid levels in closed vessels. The sensor is PVDF or ETFE, allowing The Probe
to be used in a wide variety of industries. The optional sanitary version affords quick removal and
ease of cleaning as demanded by the food, beverage and pharmaceutical industries.
The sensor houses the ultrasonic transducer and temperature sensing element. The Probe emits a
series of ultrasonic pulses from the transducer. Each pulse is reflected as an echo from the material
and sensed by the transducer. The echo is processed by The Probe using Milltronic's proven `Sonic
Intelligence' techniques. Filtering is applied to help discriminate between the true echo from the
material, and false echoes from acoustical and electrical noises and agitator blades in motion. The
time for the pulse to travel to the material and back is temperature compensated and then converted
into distance for display, mA output and relay actuation.
Installation
Environmental
The Probe should be mounted in an area that is within the temperature range specified and that is
suitable to the housing rating and materials of construction. The front lid should be accessible to
allow programming, wiring and display viewing.
It is advisable to keep The Probe away from high voltage or current runs, contactors and SCR control
drives.
Location
Notes:
• This product is intended for use in industrial areas. Operation of this equipment in a residential
area may cause interference to several frequency based communications.
• The Probe is to be used only in the manner outlined in this instruction manual.

Calibration
Calibration: Reference Method
• Adjust the material level (or target) to the desired distance from the sensor face.
• Press the “4” or “20” key (as appropriate) to view the stored distance associated with that mA
output value.
• Press the key a second time to set the new distance reference.
• After viewing or calibrating, Probe operation automatically reverts to the Run mode (6 sec). The
calibration value is referenced from the face of The Probe sensor, in the units displayed.
4 mA calibration
20 mA calibration
Operation Status
The logo will change from full to partial to indicate operation status. After the `Waiting' period, the `?'
icon will appear for an `LOE / FAULT' indication. When a valid echo is again received, a `Good'
indication will resume. Refer to Troubleshooting on page 9 .

Note: Calibration bypasses the measurement response rate.
The calibration of the mA output may be done such
that its span will be either proportional or inversely
proportional to the material level.
Note: The 4 and 20 mA levels may be calibrated in
any order.
GOOD WAITING LOE / FAULT
The graphic portion of the display gives the user a visual
indication of The Probe's operating status. Viewing the
graphic can assist the user in properly locating and
installing The Probe to achieve optimum performance.

Adjustments
There are several operating adjustments that can be made to The Probe.
• Press the "4" and "20" keys simultaneously until the desired adjustment is obtained. A viewing
sequence of the stored value is automatically initiated.
• During this time, press either the "4" or "20" key to change the value. After viewing or changing,
operation automatically reverts to the Run mode (6 sec).
Calibration, Scrolling Method
The 4 and 20 mA calibration values can be selected where reference levels, either from the material
in the vessel or from a target, cannot be provided. This method can also be used to trim the output
levels obtained by the Reference Method (see page 4).
• To change the stored calibration value, obtain the `c 4' or `c 20' display.
• Press the "20" key to increase or the "4" key to decrease the calibration value.
• After scrolling to the desired value, stop pressing the key. The display automatically reverts to the

measurement response:
is the limit to which The Probe will be able to keep up with rates of change.
If The Probe measurement cannot keep up with the rate of level change, set the
adjustment from `1' to `2'. If The Probe still cannot keep up with the rate of level
change, set the adjustment option to `3'. Avoid choosing an option that is too fast for
your application.
agitator discrimination: discriminates between agitator blades in motion, and the material (target) surface.
filter: discriminates between false echoes from acoustical and electrical noise and the
material (target) surface.
fail-safe timer:
establishes the `Waiting' period from the time a loss of echo or operating fault
condition starts until the fail-safe default is effected. Adjusting the speed of
response will set the fail-safe timer to the default values in the chart. If a different
response is required, adjust the ‘FSt’ option (see page 13).

blanking
Blanking is used to ignore the zone in front of the
transducer where false echoes are at a level that
interfere with the processing of the true echo. It is
measured outward from the sensor face. The minimum
recommended blanking value is 0.25 m (0.82 ft) but can
be increased in order to extend the blanking.

• To change the speed of response, obtain the `SP' display.
• Scroll forward through the options (1-2-3) by pressing the "20" key. Scroll backward through the
options (3-2-1) by pressing the "4" key.
• When the desired option is displayed, stop pressing the key. The display will automatically return

Alarm
• To change the alarm function or setpoint, obtain the `AL' display.
• Press the "20" key to increase or the "4" key to decrease the setpoint.
• When the display has scrolled to the desired value, stop pressing the key. The display
automatically returns to the Run mode (6 sec).
Fail-Safe
In the event a loss of echo or fault condition exceeds the `Waiting' period (see Speed of Response
on page 6 or Fail-safe Timer below), the ` ? ' icon appears and one of the following fail-safe defaults
is immediately effected.

The fail-safe timer allows the user to vary the ‘waiting’ period from the time a loss of echo or
operating fault condition begins, until the fail-safe default is effected. The ‘waiting’ period is
adjustable from 1 to 15 minutes, in 1 minute increments.
The fail-safe timer value will default to settings determined by the speed of response (see page 11).
If a different value is desired, the fail-safe timer should be adjusted
after the speed of response is
set.
• To change the fail-safe timer, obtain the ‘FSt’ display.
• Increase the ‘waiting’ period by pressing the “20” key, and decrease it by pressing the “4” key,
stopping when the desired value is displayed.
• The display automatically reverts to the Run mode (6 sec).
Units
The units of the measurement reading can be selected as follows:
1 = metres, m (factory setting)
2 = feet, ft
The selected units are also applicable to the `Blanking' and `Alarm' adjustments.
• To change the units obtain the `Un' display.
• Scroll forward through the options ( 1 - 2 ) by pressing the "20" key. Scroll backward through the

The echo is not reliable and The Probe is waiting for a valid echo before updating the
measurement.
Probable causes are:
• material or object in contact with sensor face
• The Probe is too close to the fill point
• The Probe is not perpendicular to the liquid surface
• change in level too fast
• measurement out of range
• foam on liquid surface
• high level of vibration in the mounting structure
• level inside the blanking zone
The `Waiting' period has expired. Investigate the probable causes listed above.
