INDEX

IMPORTANT NOTE: This instrument is manufactured and calibrated to meet product specifications.
Please read this manual carefully before installation and operation. Any unauthorized repairs or
modifications may result in a suspension of the warranty.

QUICK BENCH TEST:

Ultrason

Connect Sensor to the

T.DUCER terminals as shown below, then apply Power. When properly connected

a soft clicking can be heard from the sensor and figures will show on the large LCD display. Test
operation of the Ultrason by holding the sensor steadily and aiming at a flat, stable target 12 to 28" (305
to 711 mm) away from the end of the sensor. Allow a few seconds for the Ultrason to lock onto the
target before displaying its distance. The Ultrason will now display distance in ft or cm (factory
calibration).

CONNECTIONS:

POWER INPUT: The standard model requires AC power input between 100-130VAC 50/60Hz (2 amp
fuse is recommended). No adjustments are necessary for any voltage in this range. Optional 230VAC
requires power input between 200-260VAC 50/60Hz. (See OPTIONS section of this manual for
connection of optional 12VDC or 24VDC power input).

IMPORTANT NOTE

: To comply with CSA/NRTL standards, AC power input and relay connection

wires must have conduit entry to the instrument enclosure.

KEYPAD SYSTEM

The Ultrason has a simple 3-button
calibration system. Operating and
calibration modes are shown on the
16-digit alphanumeric display. The
keypad is used to move around the
menu to calibrate the Ultrason, and to
view operating mode and functions. A
beep is sounded as each key is pressed.
If the keypad is not used for 2 minutes,
the Ultrason will automatically go to

RUN mode (scrolling display). Use the

keypad to explore the Menu and
become familiar with its features.

Range mode is useful to measure the exact distance from the sensor to the zero level during
calibration, or to monitor “outage” or free space in a tank.

Level mode can be used to measure tank level in linear units, or “Head” (height of flow) in an open

channel for comparison with a flume manufacturer’s flow tables.

Vol Volume mode displays tank inventory in engineering units like gallons or liters.
Hrt Horizontal Round Tank mode sets the Ultrason to calculate and display volume units in a

horizontal round tank.

Flow mode is for open channel flow through a flume or weir.

From

Vol Hrt or Flow press È to make your selection. (Range or Level mode will bypass the

Volume units selection menu).

Vol Hrt or Flow modes will give you the additional choice of

volumetric units:

ft3 - cubic feet

USG - US gallons

USMG - US million gallons (FLOW only)

IG - Imperial gallons

IMG - Imperial million gallons (FLOW only)

m3 - cubic meters

L - liters

You can enter values up to 6 digits (e.g. 150,000 liters). When the measured tank volume exceeds 4
digits, the Ultrason will automatically display a 'multiplier' on the lower alphanumeric display.

4-20mA CURRENT LOOP OFFSET

Some applications may require the 4-20mA output to be offset so that 4mA or 20mA corresponds to a
Level, Range or Flow other than Zero and Full Scale.

4mA at - use Ç and È to set % output for 4mA. It is adjustable from -5% (3.8mA) up to 15% lower

than the 20mA setting. Adjustment resolution is 0.05% (0.01mA).

20mA at - use Ç and È to set % output for 20mA (down to 15% greater than the 4mA setting and up

to 300%). Adjustment resolution is 0.05% (0.01mA).

DAMPING

Minimum damping allows fast response to level changes. Increasing damping slows the Ultrason's
response to level changes and is ideal to smooth the display and outputs in turbulent conditions.
Damping value is shown in percent (0-99%). Some experimentation may be required to select the
optimum damping value. A value of 20% is recommended for most applications. For fast level changes
(up to ½ inch/sec - 13 mm/sec), a

Damping value of 1% is recommended. Maximum is 99%.

Ultrason

If the Ultrason is unable to obtain repeated echoes the Damping setting will be automatically set to 1%
by the instrument.

REJECTION TIME (RejTime)

Rejection Time adjustment is a powerful Ultrason feature to suppress false echoes and the effects of
transient targets such as agitators, splashing, or turbulence. Rejection Time is shown in seconds. The
time value represents the number of seconds the Ultrason must receive repeated echoes from a new
target before indicating its level on the display and outputs. The factory default is 8 seconds and should
be ideal for most applications. Decreasing this value allows the Ultrason to respond more quickly to fast
level changes, and increasing the time value allows the Ultrason to reject false echoes from slow
sweeping agitators, tank filling streams, splashing, severe turbulence and steam. Minimum setting is 1
second (for fast level changes up to 1/2 inch/sec - 13 mm/sec). Maximum setting is 85 seconds. If the
Ultrason is unable to obtain repeated echoes the
by the instrument.

RejTime setting will be automatically set to 1 second
