Models 344/345
Ultrasonic Non-Contact
Transmitters for Level,
Volume, or Open Channel Flow
D E S C R I P T I O N
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
®
and
316 stainless steel EchoMaster™ Ultrasonic Transducers
that have extensive agency approvals for hazardous
area locations.
