ultrasonic level measurement

1. Non-contact level measurement
Introducing the new LST300
BU Measurement and Analytics, February 2016

2. The integrated version has sensor and
electronics integrated into a compact
instrument. Our latest product is called the
LST300.
The Product
ABB offers two variations of ultrasonic instruments
The remote sensor version separates the
transducer with the transmitter. We call this
product the LST400.

instruments have frequent failures
 Works in the most difficult conditions
 GAP technology means it works in dust and fog
 Narrow beam angle allows installations in small spaces
 Easiest configuration
 Easy menu means 1 minute setup.
 Graphic echo display for easy diagnostics and installation in bulk solids

5. LST400 target applications
A recap - Liquids
 Water industry
 Pump control, pumping stations

LST300 represents the future of
level measurement.
Let us introduce LST300 from
ABB – the device that removes
the need for compromise on
performance an specifications.
LST300 is the first device where
you really can have it all in one
compact instrument.
The future of ultrasonic level
starts shipping March / April
2016.

12. LST300 product benefits
Measure in the most constrained spaces
 Narrow beam angle
 Other instruments need to be as much as 1m away
from obstructions
 LST300 only needs only 30cm clearance (at 5m range)
 Very quick drop-off in beam means we detect nothing
outside our beam, where others still detect smaller
echoes.
 False echo filtering
 Filters those echoes that cannot
be avoided
 Useful for submerged pumps and
agitators
 Very unique on a compact
instrument
 Especially unique to have this
visually available on a compact

13. LST300 product benefits
Automatically adapts to process conditions
 GAP technology
 The LST300 takes the already powerful GAP technology of the LST400.
 The LST300 constantly monitors measurement data, optimizing the
system for the best signal to noise at any tank size.
 This background function ensures the LST300 always runs at its best
accuracy with a reliable measurement.
 The LST300 is the easiest
device to use install, as it
requires no special setup,
automatically adapting to
process conditions.
 LST300 works on aerated
ponds, moving surfaces and
applications with some foam
where others would fail

14. LST300 product benefits
Modular design makes service easy
 Sensor is calibrated individually
 No need to calibrate sensor to electronics when
changed
 Replace communication and keep configuration
 Setting are temporarily stored in the sensor, and
transferred back to the new communication board
 Easily replace / upgrade terminal boards
 Switching between surge protected and standard
terminal is very easy
 Easily swap HMI’s
 Changing between push button, touch screen and
blind HMI is an easy swap
 LST300 is the first compact ultrasonic that can be
effectively serviced and isn’t a throw-away unit that
always needs replacement!
