Product Critical Technical Advantages
-
Cryogenic Temperature Resilience: The LNGmass is designed to operate reliably under extreme thermal stress. Its sensor architecture is optimized for medium temperatures down to –196 °C, ensuring stable and accurate mass flow measurement during the complex cooling and filling phases of LNG refueling.
-
Industry-Leading Compact Design: Space is at a premium inside modern LNG dispensers. The LNGmass offers full Coriolis performance on the smallest footprint available, allowing for easy integration into existing machine designs without requiring straight inlet or outlet piping runs.
-
Maintenance-Free Operation: Unlike traditional mechanical meters, the LNGmass has no moving parts to wear out or seize in cryogenic conditions. This eliminates the need for periodic mechanical maintenance and significantly reduces the total cost of ownership for station operators.
-
Multivariable Measurement at Subzero Conditions: In a single device, the LNGmass provides simultaneous data for mass flow, density, and temperature. This is particularly valuable in cryogenic applications where monitoring the state of the fluid is critical for both safety and accurate fiscal billing.
-
Seamless Digital Communication: The integrated Modbus RS485 interface provides high-speed, reliable data exchange with dispenser controllers. This ensures that the high-precision mass data is transmitted without signal loss, supporting accurate custody transfer and inventory management.
-
Intelligent Data Recovery: To streamline servicing, the device features an automatic data recovery system. All configuration and calibration parameters are securely stored and can be restored instantly, ensuring the meter returns to service quickly after any maintenance intervention.
