    <pre style="white-space:pre-line"><code>LILY Self-Leveling Borehole Tiltmeter

The LILY Self-Leveling Borehole Tiltmeter is a precision, dual axis
sensor package designed for specialized applications and
research. Applications include volcanic and tectonic research,
hydraulic fracture mapping, micro-deformation monitoring,
deep ocean geophysics, and more.

Using a high-precision electrolytic tilt sensor, units deliver
resolution to 5 nanoradians; dynamic range is Â±330 Î¼radians.
Units also feature a +/-10 deg. leveling range for easy
installation downhole. Output is RS232 or RS422 (RS485 full
duplex) and includes timestamp and compass bearing. Data can
be saved to file externally or to LILYâ€™s on-board flash memory
(75,000 sample max) using fill/stop or cyclic memory modes.

Units are fully submersible to 3000 psi. Titanium is also
available for +5000 psi applications. The culmination of over 30
years of tilt sensor experience and expertise, the LILY
represents the pinnacle in precision sensor engineering. Contact
Jewell Instruments today for more information about this
powerful instrument.
