Fuel Density Meter FD-5110 New

Achieves high accurate mass flow measurement with a new fuel density meter and volumetric flow detector

By connecting with the FM-3100 Digital Flow Meter, the FD-5110 Fuel Density Meter can measure temperature and density data in real time. In addition, the FP series Volumetric Flow Detectors with wide range ability and the FD-5110 are the best choice for achieving the accurate mass flow measurement.


1.Achieves low pressure loss and high accuracy in small flow rate

With the use of the FP series volumetric flow detector, the pressure loss of 20 kPa or less (at 60 L/h) is achieved. The detector can be installed with the minimum pressure fluctuations of the flow path. Compared to the FZ-2200A, the measurement accuracy in the low flow range is improved. Thus, it is ideal for starting test.

2.Compact And Light Weight System

Compact and space-saving design. (50 % size reduction compared to the existing model.)


Instantaneous massflow measurement at starting engine


3.Applicable To Various Volumetric Flow Detectors

Achieve various mass flow measurements selecting a volumetric flow detector from small to large flow.

4.Makes the procedures in mode and performance tests simple

Depending on the area and installation location, various factors such as fuel type and density are varied. Ono Sokki’s mass flow measurement system does not require the troublesome density data input etc. with real-time density measurement and mass conversion.
