Lily Borehole Tiltmeter
Self-Leveling
The
LILY
Self-Leveling
Borehole
Tiltmeter is designed for volcanic and
tectonic research and for monitoring of
hydraulic
fracturing
and
other
subsurface processes in the oil and gas
industry. LILY is the culmination of over
25 years of experience in the
fields of instrumentation and geophysics
by the engineers and scientists at
Jewell Instruments. Its small diameter
and high-pressure stainless steel
housing give it ruggedness and
versatility for demanding field projects.
DESIGNED FOR VOLCANIC AND
TECTONIC RESEARCH
The dual-axis tiltmeter senses angular
movement in two orthogonal vertical
planes using precision electrolytic tilt
sensors. The digital electronics convert
the tilt signals to an easily recorded
RS485 (RS422) data stream consisting of
tilt, azimuth, temperature, serial number
and clock time. Data output in NMEA 0183
format is a standard feature.
The LILY tilt sensors can self-level on
command through a range of ±10 degrees
and have <5 nanoradians resolution over a
dynamic range of
±330 microradians. LILY incorporates an
innovative new design* that achieves high
mechanical stability, necessary for stable
long-term measurements, at a much lower
cost than was previously possible in
instruments of this type.
