The ACE II cryogenic system is used to measure and record cryogenic liquids for truck deliveries and in-plant applications. It is paired with a Hoffer turbine flowmeter, which uses hybrid ceramic ball bearings to prolong the life of the flowmeter in fluids that offer poor natural lubricity. The system also includes a printer for delivery ticket printouts and an installation kit. Individual components may be purchased separately.

ACE II's computer features graphical display and “soft keys,” simplifying interaction between operator and instrument. Multiple messages displayed in full text help the user navigate through the instrument menu. The menu is built up hierarchically for quick access to a desired function. Electronic circuits are constructed with multi-layer boards and surface-mount components. The advanced computation algorithm provides multiple methods for calculating volume, mass and density of the fluid.

Built-in diagnostic functions allow for quick troubleshooting and identifying faulty components. Communication to external computing devices is accomplished through the RS232 serial port, and front panel infrared port. ACE II supports standard MODBUS protocol.
