capacitive
liquid
level
sensors
operate
by
measuring
the
capacitance
of
an
anti-fouling
polymer
coated
cable
immersed
in
an
aqueous
liquid.
Each
sensor
contains
a
microprocessor,
preprogrammed
with
calibration
values
matched
to
the
capacitance
of
the
above-liquid
and
under-liquid
sections
of
the
cable.
The
microprocessor
analyses
the
signal
and
computes
level
every
few
seconds.
The
level,
and
temperature
within
the
transmitter
case,
are
sent
wirelessly
by
RF
transmission
to
the
data
display.
Rainwater,
seawater,
alcohol
solutions
etc.
produce
virtually
equivalent
results
and
water
containing
suspended
sediments,
organic
matter
and
most
other
commonly
encountered
contaminants
can
usually
be
monitored
without
problems. The
sensing
elements
are
all
manufactured
from
low
maintenance
freeze-tolerant
corrosion
resistant
materials
and
are
suitable
for
use
in
aggressive
liquids. **New** Our differential pressure water level sensor option is now available for all Aquagauge products. This is suitable for depths up to about 15 meters and can be installed in a tank in a few minutes. |

The SG-ELECTRODE lead-acid battery electrolyte specific gravity (SG) sensor is based on our unique polymer-membrane electrode, designed to measure water concentration in sulfuric acid/water mixtures. The electrode is placed through the watering port of an individual battery cell so that the tip of the probe is immersed in the battery electrolyte. Equilibration (to 90%) between the electrode sensing elements and the acid solution usually occurs in about 5 minutes and readings of the composition can then be made at regular intervals ranging from seconds to hours.

m2m-manager is a versatile Next G or GSM mobile phone SMS exchange system enabling a wide range of sensors to be monitored, relays to be operated and alarms to be received. As an example, by combining the unit with our AQUAGAUGE liquid level measuring probe, it is possible to remotely determine water level in a variety of situations including rainwater tanks, reservoirs, rivers, oceans etc. Pumps can be activated and low or high level warnings received, all from thousands of kilometers away. |
