Precise measurement of fuel mass flow■
A VAF AQ-RATE Mass Flowmeter is operating on the Coriolis principle. The process connection of the Flowmeter is split internally into two identical v-shaped tubes, which are actuated at resonance frequency in opposite direction.
When fluid flows through the tubes, the input legs of the v-shape will vibrate with the same frequency as the output legs, but they are behind in time. This difference in time, called phase shift, is a measure of the mass flow through the tubes.
The magnitude of this phase shift is a measure of the mass flow rate, whilst the frequency of the complete system is a measure of the density of the fluid.

Why choose VAF AQ-Rate Flowmeters?
The VAF AQ-RATE Mass Flowmeter is available in different configurations and connection sizes. The AQ-RATE Mass flowmeters are available in the 6000 HP and the 7000 UHP series.
The 6000 HP (High Precision) versions are primarily suitable for accurate fuel consumption monitoring. They offer good accuracy and repeatability and are available in the most common connection sizes in fuel systems on vessels. For even higher accuracy and repeatability and additional applications like bunkering and fuel transfer measurement we advise the 7000 UHP (Ultra High Precision) series.
The AQ-RATE Mass Flowmeters have a digital signal processor based transmitter, enabling high precision measurements. Fast signal processing in combination with intuitive self-diagnostics makes the sensor suitable for a large variety of applications. Various input and output options make the AQ-RATE Mass Flowmeters versatile in interfacing with other systems.
AQ-RATE Mass Flowmeters are standard equipped with a built-on totaliser/transmitter (Integral). For applications at elevated temperatures or in heavy vibrating environments, it is recommended to have a separate remote totaliser/transmitter.
The AQ-RATE Mass flowmeters are also available in a special version for use in hazardous areas.
