Mechanical Diesel Fuel Meter FM4 - FM3

Mechanical meter for diesel fuel and low viscosity lubricants, for a private use, made ​​of die-cast aluminum, reliable, economical and easy to install, the meter is characterized by its excellent value for money.
The counter can be used for the measurement of fuels such as diesel, fuel oil, rapeseed oil and lubricating liquids of low viscosity.
The meter FM4 has the partial counter with 4 digits (3 digits for FM3 meter) and the total counter with 8-digit (6-digit for FM3).
The reading system of the mechanical meter is nutating disk type and has the ability to be calibrated, to ensure optimum accuracy in the measurement of the fuel flow rate.
The mechanical meter, thanks to its low resistance to the passage of the fuel, ensures the highest accuracy in the measurement of the flow and also works by gravity.
Thanks to the possibility of a 360° rotation of the dial, the meter can be installed in any position on above ground tanks or cisterns.
