MAGNETROL 335-AD1A-G5P

Echotel® Model 335
Non-Contact Ultrasonic
Transmitter for Level, Volume,
or Open Channel Flow
DESCRIPTION
Echotel Model 335 is a high performance, non-contact
ultrasonic transmitter for liquid level, volume, and open
channel flow measurement. The extremely powerful
and flexible software incorporated in the Echotel 335
results in virtually unsurpassed measurement
performance. Advanced digital signal processing
enables the 335 to perform in applications involving
in-tank obstructions, light foam and agitation.
The custom graphics LCD display module facilitates
complete setup and configuration, and displays level,
volume, flow and temperature, as well as diagnostic
information. LEDs reflect the strength of the echo. A bar
graph displays echo strength from the return signal, or
tank level as a percentage of span.
FEATURES
• Custom graphics LCD display module with operational status icons.
• Advanced digital signal processing assures reliable
measurement in difficult applications
• Dual function bar graph displays echo signal
strength or tank level
• 50 kHz transducer with 26 ft (8 meter) range
• Narrow, 7 degree beam angle for excellent focus
APPLICATIONS
• 4–20 mA output and SPDT relay for level control,
alarm, diagnostics or remote flow totalization
• Sump, well, tank and open channel measurement
• Fixed target suppression to eliminate interference
from in-tank obstructions
• Water and Wastewater treatment facilities
• Common tank shapes and 32-point linearization
table for volume calculations
• Extensive support of flume and weir calculations
for open channel flow
• Two totalizers for flow, one resettable, and one
non-resettable
• Temperature compensation over full range
of transducer
• General industrial applications
• Chemical storage tanks
• Vessels with highly viscous media
• Paint, ink and solvent tanks
• Food and beverage vessels
• Batch and day tanks
TECHNOLOGY
Non-contact ultrasonic level technology is a proven
method for accurate liquid level measurement. This
technology features the ability to measure the level or
volume of the fluid without making physical contact with
the material. This is especially important in applications
containing corrosive materials, suspended solids or
coating media.
The level measurement is made by emitting an ultrasonic
pulse from the transducer and measuring the time
required for the echo to reflect from the liquid surface
and return to the transducer. The powerful electronics
measure the time of the round trip pulse and, by
knowing the speed of sound, calculates the distance.
Since speed of sound is temperature dependent, the
transducer also measures the temperature in the vessel to
provide compensation for changing temperature.
By inputting the type and geometry of the vessel, the
intelligent electronics can calculate the liquid volume in
the vessel. In a similar operation, the Model 335 can
perform open channel flow measurement by converting
the level reading into units of volume per time. Common
tank shapes, flumes, and weirs are stored in the 335
software. A 32-point linearization table is also available
for unusual tanks or primary flow elements.
