Echotel Models 344 and 345 are full-featured, ultrasonic
non-contact transmitters that provide continuous mea-
surement for liquid level, volume, or open channel flow
applications. These versatile transmitters utilize the
latest in microprocessor-based electronics along with
powerful non-contact ultrasonic transducers, to provide
level measurement that is not affected by changes in
specific gravity, viscosity, or conductivity.
Model 344 and 345 are remote mounted transmitters
that feature a front panel keypad, and a large
16-character alphanumeric display of all parameters.
These transmitters are paired up with Kynar
316 stainless steel EchoMaster™ Ultrasonic Transducers
that have extensive agency approvals for hazardous
area locations.

F A L S E T A R G E T D E T E C T I O N When it is impossible to mount the transducer far enough away from obstructions in the vessel a unique false target detection feature can be used. This target detection mode programs the transducer to search for, and display, the distance of the target nearest the trans- ducer. - Page 5 T R A N S D U C E R S P E C I F I C A T I O N S Model 384 Model 385 Transducer frequency 38 kHz 50 kHz Maximum range 35 feet (10.7 meters) 25 feet (7.6 meters) Maximum span 33.5 feet (10.2 meters)
