Installation Guide
ORCA Sonar System

ORCA Transmitter – Mounting Requirements
Select a suitable mounting position, preferably not in
direct sunlight. If necessary utilize a sunshade.
Observe the maximum and minimum temperature
specification.
Do not mount the sonar transmitter near high sources
of EMF, such as motor starters, variable speed drives
or 3 phase cables. Avoid mounting in high vibration
areas, or use rubber absorption mounts.
Be careful when removing the cable and compression
glands.
Installation Guide
Sonar Transducer – Mounting Requirements
The transducer should be half submerged in the liquid
and the transducer face must always be submerged.
Wrap cable entry and lower connection cable with
Teflon tape
Round Tanks – Centre Feedwell
Mount the sonar transducer and cleaning mechanism,
approximately one third radius between the outside
tank wall and the feedwell. This is the same whether it
is a moving or fixed bridge installation.
Do not mount near high infeed turbulence.
Choose a site installation where the infeed is least
disturbed.

Rectangular Tanks – End Feed
Mount the sonar transducer and cleaning mechanism
away from high infeed turbulence. A clearance of
700mm from the side wall.
Do not mount directly over scraper, chain
mechanisms. Choose a site installation where the
infeed is least disturbed.
Ball oat
Mount the floating sonar transducer and cleaning
mechanism as close as practicable to the launders.
Mount at least 1.00 metres from side walls. Ensure
alignment guides are installed on the mounting
bracket for decanter ranges above 500mm.
Impact Plates
Leave an extra 2 turns of cable where the transducer
connects to the actuator to minimise stress and wear
on the cable (see Impact Plate Assembly).
