Liquid Nitrogen Temperature and Depth Monitoring

Manual checks can’t tell you what’s happening inside your tank. LevelSense™ monitors liquid nitrogen (LN2) depth and cryogenic temperature continuously — alerting your team before levels reach a critical threshold, not after specimens are already at risk.

Adaptive Calibration™ — Validates on Every Fill

LevelSense™ uses Adaptive Calibration™ — validating sensor performance against the physical constant of liquid nitrogen at -196°C on every fill cycle. CLIA calibration verification requirements satisfied automatically, without periodic bench recalibration.

Track Evaporation. Predict Fills. Prevent Failures.

LevelSense™ tracks LN₂ evaporation rate and usage patterns over time. Abnormal evaporation signals early tank degradation before it becomes a critical failure. Optimized fill schedules mean fewer emergency fills and lower operating costs.

How does LevelSense™ monitor liquid nitrogen tanks?
An in-tank probe continuously reports liquid nitrogen (LN₂) depth and temperature. It provides the earliest tank failure alerting of any system available — detecting vacuum loss in approximately 25 minutes, outer tank temperature rise in 15–40 minutes, and internal temperature changes in 8–13 hours. An optional external probe detects catastrophic tank failure.
What makes LevelSense™ different from other liquid nitrogen monitoring systems?
Three things. First, detection speed — vacuum loss detected in approximately 25 minutes, earlier than any other available system. Second, Adaptive Calibration™ — sensor performance validated against the physical constant of liquid nitrogen at -196°C on every fill cycle, satisfying CLIA calibration verification automatically. Third, seamless integration — LevelSense™ plugs into your existing PharmaWatch sensor radio with no additional infrastructure.
What is Adaptive Calibration™ and why does it matter?
Adaptive Calibration™ is LevelSense™’s patented methodology that validates sensor performance against the physical constant of liquid nitrogen at -196°C on every fill cycle. This satisfies CLIA calibration verification requirements without periodic bench recalibration — no service visits, no downtime, no monitoring gaps.
What happens if a tank starts to fail?
LevelSense™ detects the earliest signs of tank failure and alerts your team immediately via call, text, or email. Vacuum loss is detected in approximately 25 minutes. Outer tank temperature rise fires in 15–40 minutes. Internal temperature changes detected in 8–13 hours. Three-tier escalation ensures alerts reach a human who can act — at any hour.
Can LevelSense™ track evaporation and fill schedules?
Yes. LevelSense™ continuously tracks LN₂ evaporation rate and usage patterns. Abnormal evaporation signals early tank degradation. Historical usage data enables optimized fill schedules — reducing emergency fills and lowering operating costs over time.
What compliance standards does LevelSense™ support?
LevelSense™ supports FDA HCT/Ps and CGTP, FDA 21 CFR Part 11, CAP, CLIA (via Adaptive Calibration™), AABB, and FDA GxP and GLP requirements for cryogenic storage. IQ/OQ/PQ validation documentation is included in every deployment at no additional cost.
Does LevelSense™ require additional infrastructure?
No. LevelSense™ is plug-and-play and integrates seamlessly with your existing PharmaWatch sensor radio. No additional infrastructure, no IT involvement, no network credentials. It reports data to the PharmaWatch dashboard exactly like all other PharmaWatch probes.
Can LevelSense™ monitor multiple tanks across different locations?
Yes. All liquid nitrogen tanks appear on your existing PharmaWatch dashboard alongside every other monitored environment. One login, one view, 3 clicks to any data point — from any device, anywhere.
