The Piusi K400 fuel flow meter is a precision instrument engineered to accurately measure the quantity of diesel, oil, or windscreen fluid utilized in various applications. This advanced oval gear fuel counter meter is highly regarded in automotive garages and workshop environments, as well as in low-flow diesel transfer settings. The Piusi K400’s operating principle, based on oval gears, ensures a high degree of measurement accuracy while minimizing pressure loss.

Available in two distinct versions, the Piusi K400 fuel flow meter caters to different fluid types: one version is designed for diesel and oil, while the other is optimized for windscreen fluid. For added convenience, both models can be integrated into a nozzle, facilitating easy viewing and usage (refer to related products for more information).

Important Note: When using the meter with Hydrotreated Vegetable Oil (HVO), recalibration is necessary to account for its specific gravity (SG) of 0.78, compared to diesel’s SG of 0.84.
