Overview Overview System Description The ACE II, Advanced Cryogenic Electronics, is a truck mounted flow metering system for delivery of cryogenic fluids. The system uses an internal computer to record and display deliveries in the required units. An optional printer allows the system to print delivery information and ACE II setup parameters. ACE has been designed to meet the requirements of the cryogenic metering section of NIST HANDBOOK 44 and OIML R-81. Typical ACE II system consists of a turbine flowmeter, flow computer, a metering run mounted on the delivery truck, and an optional...
