Installation Guide
Sultan Acoustic Wave Series
Minimum Insertion
The transducer face or cone must be at least 50mm
(2 inches) inside the tank.
If the transducer needs to be mounted above the roof
line, use an appropriate standpipe or nozzle.
Moisture Seal
Sultan Integral and Smart units have cable glands
with a moisture seal which must be tightened around
the cable. Any unused glands must be plugged and
sealed.
Transducer Location
It is vital that the Transducer has a clear view of the
product surface at all times and is kept away from
the inflow to avoid interference.
Blanking Distance
The unit will ignore any echoes and will never
measure within its Blanking distance.
Minimum values must be respected. Where possible
use the conservative values and increase this
distance by 50% if there is foam, dust, steam, or
condensation in the vessel being monitored.
(Refer to Blanking Distance table.)
If using a flange mounting, use a rubber or neoprene
gasket and washers. If using a nipple mounting,
ensure that the mounting bracket is >6mm (0.24 in)
from the rear of the transducer. Do not over tighten
the lock nuts.
