Echotel ® Model 961/962
Ultrasonic Level Switches
D E S C R I P T I O N
Increasing demands for compliance with safety systems
and overfill protection has mandated more reliable point
level measurement. Echotel® Models 961 & 962 Ultrasonic
Level Switches meet these demands with advanced transducer designs, extensive hazardous location approvals,
and a new self-test technology.
Model 961 offers the ultimate solution to reliable single
point liquid level measurement. This advanced switch
uses pulsed signal technology for superior performance in
difficult process conditions, and to provide excellent
immunity from sources of electrical noise interference.
Extensive self-testing of the electronics and transducer
make this advanced switch suitable for use in Safety
Integrity Level (SIL) 2 loops.
Model 961
Model 962 is a dual point switch that can be used as a
level controller, or to control pumps in an auto fill or auto
empty mode. The tip sensitive lower gap performs well in
aerated or foamy liquids, and can measure to within 1⁄4" of
the vessel bottom. The rigidity of the unique flow-through
upper gap allows separations of up to 128" (325 cm)
between the upper and lower transducer gaps.

Model 961/962 switches utilize ultrasonic energy to detect
the presence or absence of liquid in a single or dual point
transducer. Ultrasonic contact level technology uses highfrequency sound waves that are easily transmitted across
a transducer gap in the presence of a liquid media, but
are attenuated when the gap is dry. Model 961/962
switches use an ultrasonic frequency of 2 MHz to perform
this liquid level measurement in a wide variety of process
media and application conditions.
Ultrasonic
transducer
The transducer uses a pair of piezoelectric crystals that are
encapsulated in epoxy at the tip of the transducer. The
crystals are made of a ceramic material that vibrates at a
given frequency when subjected to an applied voltage.
The transmit crystal converts the applied voltage from the
electronics into an ultrasonic signal. When liquid is present
in the gap, the receive crystal senses the ultrasonic signal
from the transmit crystal and converts it back to an electrical signal. This signal is sent to the electronics to indicate the presence of liquid in the transducer gap. When
there is no liquid present, the ultrasonic signal is attenuated and is not detected by the receive crystal.

Ultrasonic signal transmission

gap is dry. This technology also provides excellent immunity from electromagnetic noise interference.
Pulsed signal technology makes the 961/962 units more
reliable than older continuous wave ultrasonic switches.
Unlike many tuning forks, pulsed signal ultrasonic
switches do not need to be configured for different media
densities, making these units the most universally applied
level switches on the market today.
LEVEL
Critical process control applications demand reliable instruments that provide high levels of safety. The introduction of
standards such as IEC 61508, IEC 61511 and ISA 84, have
generated interest in using Safety Instrumented Systems
(SIS) as a means to define the reliability
of instruments in a control loop. All

TECHNOLOGY
Challenging process conditions such as
aeration, suspended solids, and high
viscosities are easily handled with the
pulsed signal technology utilized in the
961/962 switches. Pulsed signal circuitry
drives the transmit piezoelectric crystal
to produce powerful pulses of high-frequency ultrasonic
energy. These ultrasonic pulses are readily transmitted
through liquids, but are attenuated when the transducer

AND
Ultrasonic switches are often used as the
last means of detecting whether a

vessel will overflow and cause a

Electron
e
empty out and possibly cavitate the
Nois
pumps. In these critical applications it is
desirable to have a method of periodically testing the
ultrasonic switch to ensure that it is functioning properly.
Model 961/962 switches feature an advanced self-test
technology that not only tests the electronics, transducer,
and piezoelectric crystals, but also tests for the presence
of industrial sources of environmental noise. Should the
switch detect any problems a malfunction output is generated to alarm the user, and a red LED is lit to indicate
an alarm condition.
DIAGNOSTICS
Taking diagnostics one step further is the unique noise
self-test mode feature that is standard in all 961/962
switches. This tests for electromagnetic and acoustical
noise that can influence many instrumentation technologies. If high levels of environmental noise are detected,
the electronics reports a fault condition to alert the user
of potential instrumentation reliability concerns.
A microprocessor in the 961/962 electronics continuously
monitors all self-test data. Should a fault occur, the microprocessor can determine whether the malfunction is due
to the electronics, transducer, piezoelectric crystals, or the
presence of environmental noise. A pushbutton and Fault
LED is used to assist in troubleshooting the switch:
5 One flash of the Fault LED indicates a problem
with the transducer or piezoelectric crystals
Self-test is performed automatically and continuously several times per second to verify proper operation of
961/962 switches. In addition, a pushbutton is provided to
initiate a manual self-test mode. Pressing this test button
stops all transmit pulses, which simulates an electronics
failure. This failure is reported as:
55 Two flashes of the Fault LED indicates a
problem with one of the electronics boards
555 Three flashes of the Fault LED indicates
excessive levels of environmental noise
• 3.6 or 22 mA (selectable) with current shift output units
• SPDT malfunction relay de-energizes with relay
output units
ADJUSTABLE
TIME
DELAY
Turbulence and splashing can cause
some fixed time response switches to
produce false level alarms. Model
961/962 switches overcome this difficulty
with an adjustable time delay feature.
RELIABLE
TRANSDUCER
Dependable point level measurement
begins with reliable sensor design. Over
30 years of ultrasonic level switch technology experience is behind the Model
961/962 single and dual gap transducers.
The result is an extremely robust transducer design that offers superior performance in difficult process conditions.
A potentiometer allows a 1⁄2 to 45 second delay to be set
to disregard waves or splashes, and reliably detect the
true liquid level.
DESIGN
Model 961 single point has a tip-sensitive transducer with
an arch-shaped gap for superior performance in aerated
or foamy liquids. Dual point Model 962 features a tip sensitive lower gap and flow through upper gap. This robust
design allows separations of 125 inches (318 cm) between
the upper and lower transducer gaps.

APPLICATIONS
T Y P I C A L
High Alarm
Model 961 single point switches may be used for high or
low level alarm, as well as for pump protection. The Model
962 dual point unit is typically configured to measure
high/low, high/high, or low/low levels.
Fill Line
Dual Point Alarm
The single point 961 can be mounted vertically or
horizontally in vessels, bridles, or pipes. The dual gap 962
is always top mounted.
A broad selection of transducer materials allow the 961/962
to be used in a wide variety of process media. Metallic
transducers include 316 SS, Hastelloy® C, and Monel®. The
316 SS transducer has a NACE construction option for sour
gas service, and can also be built per ASME B31.1 and
B31.3 piping codes. Thermoplastic transducers include
Kynar® and CPVC. These corrosion resistant plastic transducers feature a stiffening tube that runs the length of the
transducer for extra rigidity. Kynar-faced 316 SS flange
options are offered with the Kynar transducers.

A DIP switch on the Model 962 allows it to be configured
to control level, or to function as a pump controller. In the
pump control mode the unit can perform auto fill or auto
empty of tanks, sumps, or wet wells. The tip sensitive
lower gap allows liquid levels to be pumped down to
within 1⁄4" from the bottom of the vessel. The rigidity of the
flow through upper gap allows the 962 to be used even
when sumps experience severe turbulence from vessel
fill lines.
H Y G I E N I C
Spray Ball
The hygienic version of the Model 961 features a deep
drawn stainless steel electronics housing. Tri-Clamp® and
DN65 Varivent hygienic process connections are offered for
use in food & beverage, pharmaceutical, and biotechnology
applications. These hygienic transducers have 3-A
(Authorization #596), EHEDG certification (per TNO Report
# V4772/01) and a 20 R a finish to provide a uniform and
ultra-smooth surface that inhibits microbial growth.
Electron beam welding technology is utilized to facilitate a
crevice-free surface inside the transducer tip. This allows
these transducers to be used in a wide variety of hygienic
applications where CIP (Clean-in-Place) is used to remove
any contamination from the transducer surface.
