Product Features:
Piusi K33 Fuel Flow Meter - Oil
The Piusi K33 mechanical fuel flow meter measures the exact quantity of the dispensed diesel fuel or oil through a nutating disk system. Popular on OEM tank manufacturer pump kits, this fuel counter meter is able to measure up to 999.9 litres. K33 flow meter has a mechanical display that indicates to the user how much fuel has been used. Made by Italian manufacturer Piusi, the K33 oil and diesel flow meters are reliable, easy to install and calibrate options, whilst still being cost effective due to its mechanical rather than digital design.
Thanks to its flow range the Piusi K33 diesel fuel flow meter is compatible with many different pump and gravity installations. This combined with the fact that its face can be rotated to allow the flow from four directions makes this Piusi flow meter a flexible solution (flows left to right as standard).
If you need a fuel flow meter for use in flammable environments, we offer the Piusi K33 ATEX version, suitable for dispensing gasoline, kerosene and diesel dispensed in a highly flammable environment.
Please note: If being used with HVO, the meter should be re-calibrated based on it's SG of 0.78 (diesel is 0.84).
