Dual functionality in a single device
November 1st 2011 Providing reliable dual functionality,
the Echotel Model 962 from
Magnatrol offers two setpoints on
the same transducer, a
tip sensitive lower gap
and a special flowthrough
upper gap.
This dual-gap design
allows the unit to be
used for low and high
level alarm, high and
high/high level alarm,
low and low/low level
alarm, or for pump
control in an auto
fill/empty mode.
By using the pulsed ultrasonic
wave technology, the Model 962 is
less sensitive to buildup, aeration,
foam and turbulence. Response time
is less than 0.5 seconds.
The Echotel 962 includes
adjustable time delay (up to 45
seconds) and a test button for the
output signal. Other LEDs indicate
proper operation and
malfunction conditions;
identification of the
malfunction and a
separate error signal are
also standard.
Another benefit
claimed is that the Model
962 is not sensitive to
density or liquid change
and therefore does not
require any calibration. More articles from Meech International Ltd: |
