These instructions provide information for Mounting, Process and Electrical connections
and Field Programming of the echOsonix transmitter.
The echOsonix incorporates a transducer for sending and receiving an ultrasonic signal and
an electronics processing package. The ultrasonic signal is very powerful and may cause
hearing damage - refer to the safety instructions on page 3. The electronics package is either
mounted on top of the transducer or in a remote location connected by a shielded cable.
Prior to installation, review these instructions entirely. Transducer mounting location is
critical to proper operation. Most settings can be programmed prior to installation.
The PC boards are serialized to each unit and should not be removed
except by the factory. Removing the PC board will render the warranty
null and void.

Safety
Electrical Safety
The echOsonix is an electrically powered transmitter. Common electrical safety procedures
must be followed when working with this equipment. All wiring should be per local and
national standards. Do not remove the enclosure cover unless the area is known to be non-
hazardous. Do not handle circuit boards when energized.
Sound Protection
The echOsonix produces intense sound pulses. SOR recommends checking local safety
standards for Applicable hearing protection regulations.
Do not aim the transducer of an operating echOsonix at anyone’s head.
Permanent hearing damage may result. Use proper hearing protection when
operating in an enclosed space.
These values are based on dB (Lin) Peak, unweighted. Consult local sound protection
standards for conversions and limits.
Electrostatic Discharge (ESD) Handling Procedure
The SOR electronics instruments are designed to the highest quality standards. These
products use highly sensitive electronic components that are affected by static electricity,
that is present in most work environments. The following procedure is recommended to
reduce the possibility of component failure caused by static electricity damage.
n
Use a grounded wrist strap when installing or removing electronic boards. A grounded
workstation is recommended.
n
Ensure that all electrical connections are made and none are partial or floating. Ground
all equipment properly.
n
To prevent ignition from static charge buildup, use a damp cloth when cleaning the unit.

Quick Start Installation Guide
This guide is intended to be a quick reference only. Please refer to each section of this form
for details on installation, wiring, set-up and operation. Contact the factory or your local
representative if you have any questions or concerns.
Install the transducer away from obstructions. Do not mount in the center of domed or
conical roof tanks. See page 6 for minimum mounting distance from tank walls.
Wire the unit according to local and national safety codes. Power and signal wiring must be
run as a minimum. Refer to pages 11-17 for more wiring details.
NOTE: Proper earth grounding of electronics is critical!
Flanged Mounting
Avoid mounting end of transducer
assembly inside standpipe.
Use a shorter standoff so
end of transducer assembly
is inside vessel, or...
Extend standpipe into
the vessel and cut the
end at a 45
o
angle.
Use a threaded coupling
directly on top of the
vessel, or...
Extend standpipe into
the vessel and cut the
end at a 45
o
angle.
See page 9

Calculate the level distances for
the vessel. These will be entered
when programming the unit.
All values are measured from
the transducer face down to the
desired level. See pages 23-24
for details of each value.
NOTE: All values are measured
from the transducer face down.
Hi Level will be a smaller number
than Lo Level.
Program the basic parameters in the setup menu. Press CAL to access the menu. Enter the
Application Type, Hi Level, Lo Level and relay settings using the values calculated in the
above step. See pages 26 and 27 for menu structure and description.
NOTE: Push-button interface is the

Mounting the Transducer
For all applications the transducer is mounted above the process pointing directly down at
the measured surface. In open or flat topped vessels the transducer should be mounted
so that the primary cone of sound does not intersect the wall of the vessel, if possible. The
table below lists typical guidelines for minimum mounting distances from the wall. If the
radius of the vessel is less than the minimum distance, consult the factory for assistance.
Vessel Height
For vessels taller than 40 feet (12m), use:
Minimum Distance = Vessel Height x 0.087

Minimum Mounting
Distance
Transducer mounting placement is critical. The
transducer assembly generates both the sound
pulse and monitors the echoes. The sound pulses
travel away from the face of the transducer in a
cone-shaped pattern. This area should be free of
obstructions and away from inlets.
The transducer should be mounted in a position
that allows unobstructed access between the
face and the process to be measured.
Inlet Pipe
NOTE: A good rule of thumb is to look down
inside the vessel through the mounting
location. You should be able to see a clear
path to the process material without any
physical objects or ll streams in the way.

Alternative Mounting
echOsonix units may be mounted inside a stilling well or bridle to avoid excessive
obstructions or turbulence in the process. Follow the guidelines shown below for the
stilling well or bridle, then see page 38 for special instructions.

echOsonix units are designed to read solids materials and ignore the angle of repose. The
angle of repose is the angle between horizontal and the side of the pile of material. For
processes where the angle of repose is greater than 45 degrees, the echOsonix may require
some special tuning or setup. Contact the factory for these situations.
For solids installations, the echOsonix should be mounted in a vertical position according to
the diagram below. Do not “aim” the transducer to the angle of repose, this is not necessary.
Mount the transducer 1/3 of the distance from the vessel wall to the vessel centerline, away
from any internal obstructions.
For vessels that fill and discharge from the center, this mounting location will provide a
good average level measurement. As solids pile up they form a cone, and as they
discharge they form a conical pit. By measuring the level at the 1/3 radius position
shown, an average level is obtained for both situations. For vessels that do not fill and/or
discharge from the center, a mounting location should be chosen that will provide the best
possible average level.

echOsonix transducers may be mounted using a threaded connection or a flanged
connection. Some units require flange mounting. There are two options for thread
mounting which are detailed below. In all cases, the transducer should be installed in
a stable, permanent mounting fixture.
Focusing Cones
All units are supplied with some form of focusing cone to be mounted on the transmitting
end of the transducer. These cones should always be installed according to the instructions
in this manual. If the mounting method inhibits this cone, the mounting should be modified
to account for it. The cones are vital to proper performance and should not be modified
or removed.
Thread Mounting
Short-range transducers (30, 20 and 15kHz) may be supplied with a 3” NPT mounting
thread. All remote transducers are also supplied with a 1” NPT/BSP cable nipple that can be
used for either conduit connection or mounting.
Flange Mounting
When mounting a unit with a flange, we recommend using non-metallic bolts. The
mounting bolts should be hand-tight only. Do not over-tighten the bolts, this can affect
performance of the echOsonix transducer.
Most flange mounts use a standpipe. It is important to follow the guidelines below for
standpipe design. Methods are shown in order of preference - Method 1 preferred, etc.
