The Hoffer ACEII Cryogenic System
The ACE II Cryogenic System incorporates the newest technological
advances in electronics and the time proven solutions in cryogenic
measurement. The ACE II Cryogenic System is used to measure
and record LIN, LOX, LAR, CO2 and other cryogenic liquids
for truck deliveries and in-plant applications. The design
is directed toward cryogenic service with ease of maintenance
in mind.
The ACE II Cryogenic System 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.
The ACE II computer offers many features including graphical
display and “soft keys” allowing easy interaction
between operator and the instrument. Multiple, easy to follow
messages displayed in full text help the user to navigate
through the instrument menu. The menu is built up hierarchically
for quick access to a desired function. Electronic circuits
are constructed with rugged, multi-layer boards and SMT (surface
mount components). The advanced computation algorithm provides
multiple methods for calculating volume, mass and density
of the fluid. Extensive 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.

The ACE II Cryogenic System complies with Handbook 44
(NIST), MIL-STD 810B Shock and Vibration, NBS TN 361,
ASHRAE Physical Properties of CO2, State of California
Weights and Measures, and CE for Europe.
