• average fueling time: only 3 min/450l
• measurement accuracy better than 0.25%
• card-operated and/or self-service operation
• can be supplied as part of a mobile or stationary LNG fueling station
• MID approved
• digital display showing price, amount of gas in kg and price per kg
• recycling of boil-off gas for a low pollution rate

Dynaflow 3000 provides operators with accurate, real-time dynamic density measurement, which assures a very precise mass flow calculation. Every dispenser is equipped with a quick-connect LNG nozzle and compressed air cleaning connection.
Metering components are electronically and mechanically pre-tested and factory calibrated. On site performance tests validate that the process performances of the refueling stations are met.
Dynaflow 3000 complies fully with ATEX safety requirements.

Fields of application: LNG-Dispenser, Truck-Filling, Ship-Filling, IMC-Station, Transport

Each device can be tailored technologically according to customer requirements and branded accordingly.

Integrated connectors to our Mastermeter device ensure simple, fast and accurate calibration.

MiniBulk Distribution System (MBDS)

Specifically designed for delivering CO2 to breweries and restaurants for beverage carbonation. The system fits into a regular van, which is important as the delivery sites are often located in residential areas that prohibit larger vehicles through noise and access restrictions.
