FM-66 uses a precision gear mechanism that measures fuel flow through rotating gear displacement, ensuring stable and consistent accuracy even under varying flow conditions.
Large digital display shows real-time flow and total volume. The reset function allows fast clearing for batch operations.
The display head can rotate freely, making installation flexible in horizontal or vertical pipelines.


FM-66 is used to measure fuel flow in diesel, gasoline, kerosene, and similar light oil transfer systems. It is widely used in fuel dispensing stations, mobile tanks, construction equipment, and industrial fuel monitoring systems. It provides real-time measurement of flow volume to improve fuel management accuracy and reduce wastage.
The FM-66 offers an accuracy of ±1%, making it suitable for most commercial and industrial fuel measurement applications. Its gear-based measurement system ensures stable readings even under continuous operation or variable flow conditions.
Yes, FM-66 supports 360-degree rotation of the display head, allowing flexible installation in horizontal, vertical, or angled pipelines. It can also be installed inline or directly connected to fuel dispensing nozzles.
Yes, FM-66 uses a small internal electronic system powered by batteries (depending on configuration). It does not require external power supply, making it suitable for mobile fuel systems and remote locations.
FM-66 is compatible with diesel, gasoline, kerosene, biodiesel, and other low-viscosity petroleum-based fluids. It is not recommended for high-viscosity or corrosive chemical liquids unless specially customized.
