L II ™ Fluid Monitor for Tanks. The S

L
EVE
L II ™
represents the latest in state of the art liquid monitoring equipment
for stationary tank applications. The S
EE
L
EVE
L II ™ is designed for
reliable and accurate level, volume, and temperature measurement
of sour or sweet crude oil, chemicals, acids, water, or fuels. The
liquid level is determined by sensing the position of a magnetic
float using a series of reed switches arranged in a vertical sensing
bar. This technology has no moving parts except for the float,
and can operate over a range of product temperatures from
-40°C to +90°C (-40°F to +194°F). The temperature is sensed by
semiconductor temperature probes spaced every 16 inches along
the inside length of the bar.
The S

EVE
L II components are weatherproof to allow installation
in any environment. Most monitor functions operate entirely
on internal batteries, so external power is not required in many
applications. The displays can be continuously seen in the daytime
and are visible at night with the push of a button. All functions
on the gauge, including calibration, alarms, and security, can be
programmed with the built in keypad. Remote communications,
via 4-20mA or 1-5V standards, and alarms are available via terminal
blocks inside the gauge display.
