The FZ-2200A Massflow Meter is Coriolis flow meter that accurately measures the flow of fuels such as gasoline, light oil and kerosene. It is used in combination with the FM-3100 Digital Flow Meter that incorporates the FM-0321 module for the FZ series. The FZ-2200A Massflow Meter is capable of measuring continuous mass flow, making it suitable for the measurement of fuel flow during mode operation, and in-line measurement of fuel density at the same time of mass flow measurement. It can measure fuel consumption from passenger vehicles and medium trucks to large vessels. (As for small flow rate, made to order. Please make sure to check the measurement range when selecting a product.)


Principle of flow measurement

The FZ-2200A Massflow Meter gives characteristic vibration to the tube to cause a motion that corresponds to the angular velocity, generating Coriolis force (Fe). The tube that is generating Coriolis force (Fe) causes its twist that is proportional to the mass flow as shown below. The mass flow is calculated based on the amount of this twist.




Princicle of density measurement

The free vibration frequency of tube in the FZ-2200A Massflow Meter is determined of the spring constant of the tube and the sum of the tube mass and liquid mass in the tube. Thus, the vibration frequency varies depending on the liquid density. From the above, liquid density is measured based on the vibration frequency of the tube.




Continuous massflow measurement with high accuracy

It enables to measure mass flow rate continuously every 100 ms. The measurement range is 1 to 1,090 kg/h, accuracy is within ± 0.1% of reading (27 to 1,090 kg/h).
