Echotel
®
Model 355
Non-Contact Ultrasonic
Two-Wire Transmitter
for Level, Volume, or
Open Channel Flow
DESCRIPTION
Echotel
®
Model 355 is a two-wire, loop-powered, non-
contact ultrasonic transmitter that performs liquid level,
volume, and open channel flow measurement. Model
355 Transmitters feature a powerful 60 kHz ultrasonic
transducer and advanced digital signal processing to
reliably measure out to a 20 feet (6 m) maximum range.
The Model 355 provides unsurpassed ease of
configuration with either the menu-driven
4-push-button, 2-line
×
16-character display, HART
®
digital communications, or PACTware
. This enables a
complete configuration to be performed via the local
user interface, or remotely with the extra capability of
capturing echo wave forms, and viewing trend data,
diagnostic conditions, and all transmitter configuration
parameters.
The integral mount electronics are housed in either a
cast aluminum housing or Lexan
®
thermoplastic
housing. The intelligent electronics analyze the
ultrasonic echo profile, apply temperature
compensation, reject echoes from false targets, and then
processes the true echo from the liquid surface. This
results in an extremely reliable measurement even
when applications difficulties like turbulence and false
echoes exist.
The 60 kHz ultrasonic transducer is offered in
polypropylene, or Kynar
®
Flex for superior performance
in harsh environments. These powerful transducers
feature a 10° conical beam and 10
"
(250 mm) blocking
distance to maximize measurement capabilities in a
wide variety of applications.
