Rainwater harvesting
The ILLSU is designed for use in
continuous submersion in liquids such as
water, oils and fuels in small tanks, where
conventional mechanical level switches
and sensors are not ideal and more level
‘control’ and measurement is required.
The probe uses a piezo-resistive silicon
sensing technology, isolated from the
media by a diaphragm within the stainless
steel housing It offers excellent stability,
repeatability and resolution for
applications where a small tank level is
required, from as low as 3ft through to 40
ft high tanks.
Each device is temperature compensated,
calibrated and supplied with a traceable
serial number and calibration certificate.
