Liquiscale

Secure level measurement for cryogenic pressure vessels

LiquiScale is a reliable level measurement device for pressurized cryogenic gas tanks. Our system is based on drift-stable differential pressure technology (drift less than 0.3% over 10 years) and reliably monitors level and head pressure.

LiquiScale – Greater Safety, Higher Efficiency and Sustainable Tank Logistics

With LiquiScale, J.con GmbH offers an intelligent solution for precise and reliable level measurement in cryogenic storage tanks and pressurized liquefied gas tanks. LiquiScale not only provides dependable measurement values, but also delivers full transparency regarding the actual tank condition – at any time and regardless of location.

Thanks to highly precise electronic differential pressure measurement combined with thermodynamic level correction, the actual tank content can be determined far more accurately than with conventional measurement methods. This level of accuracy makes it possible to specifically reduce safety margins within the tank without compromising operational safety. As a result, the available tank volume is utilized more efficiently, with reserves becoming visible and predictable.

When connected to the J.con Tank Portal, LiquiScale becomes a central tool for optimized tank logistics. Accurate level data enables demand-oriented and predictive refill planning, avoiding unnecessary delivery trips. This not only reduces fuel consumption and operating costs, but also contributes to lower CO₂ emissions and more sustainable supply processes.

LiquiScale Generation 3 – Intelligent Connectivity

The next step in digital and networked level measurement for cryogenic tanks with bidirectional communication.

LiquiScale Generation 3 combines maximum measurement accuracy with modern communication technology, with a clear focus on bidirectional data exchange. This integrated communication enables not only the transmission of measurement data, but also active remote access to the device.

Via the J.con Tank Portal, measurement values can be monitored, parameters adjusted, limit values modified and system settings updated – across locations and in real time. This makes LiquiScale Gen. 3 a key component of modern remote monitoring and service concepts.

The technical foundation is a SIL 2 certified differential pressure sensor with a long-term drift of less than 0.3 % over ten years. In addition to level measurement, top and bottom pressure can also be recorded and displayed depending on configuration. Values are clearly presented in percent, liters, kilograms or normal cubic meters.

Key features:

High-precision level measurement for cryogenic storage tanks
Bidirectional communication with the J.con Tank Portal
Remote monitoring, remote parameterization and configuration changes
SIL 2 differential pressure sensor with high long-term stability
Thermodynamic level correction & geometry-independent calculation
High-intensity LED color display with traffic-light logic
WLAN configuration and optional LTE connectivity

LiquiScale Flex – Autonomous & Mobile

The flexible variant for mobile tanks and remote applications without permanent power supply.

LiquiScale Flex is designed for mobile tanks and remote applications where no permanent power supply is available. It offers the same high measurement accuracy and reliability as the stationary LiquiScale devices, combined with maximum independence and mobility.

LiquiScale Flex operates energy-autonomous and is powered as standard by an integrated solar cell with battery backup. For locations with permanently limited lighting, an additional external solar panel can be installed. This ensures reliable, autonomous operation even at very dark or shaded sites.

Via optional LTE connectivity, LiquiScale Flex can communicate seamlessly with the J.con Tank Portal. This enables reliable remote monitoring of fill levels in mobile and autonomous tanks, optimizing refill planning and reducing manual inspections.

Key features:

Level measurement for mobile and remote liquefied gas tanks
Energy-autonomous with integrated solar cell and battery backup
Optional external, flexibly positionable solar panel
High-precision SIL 2-certified differential pressure measurement
Connectivity to the J.con Tank Portal via LTE
Convenient web-based configuration
Suitable for oxygen applications
