SPECIFICATIONS
INSTALLATION
Unpack the transmitter carefully. Inspect all units for damage. Report any damage to carrier immediately. Check the
contents against the packing slip and purchase order. Kenco’s SmartSonic Acoustic Wave Transmitters are
manufactured to the highest quality standards. These instruments use electronic components that can be damaged by
static electricity. Make sure that you are properly grounded before starting installation. Insure that all electrical
connections are properly made, and that there are no “floating” connections.

The SmartSonic Transmitters consist of two main components:
• The Electronics
• The Sensor (Transducer)
The transducer contains a piezoelectric crystal that converts an electrical signal
from the electronics, into acoustic (sound) waves. These acoustic waves are
directed through the air toward the process media surface. They are then
reflected off of this surface and returned to the transducer. The piezoelectric
crystal then converts the received waves into an electrical signal which is
analyzed by the electronics.
The time difference between the transmitted wave and the received wave is
proportional to the distance from the face of the transducer to the process media
surface. This distance is used by the electronics to calculate level or open
channel flow in the units selected by the operator.
