The PIUSI K33 and K44 mechanical flow meters offer an excellent solution for accurate and reliable measurement of diesel fuel (including HVO and XTL fuels) for non-commercial use. These robust, high-quality meters are ideal for agricultural, logistics, mining, construction, and general industrial applications where precise tracking of dispensed quantities is essential.
The K33 and K44 models combine PIUSI's reliability and ease of use, ensuring long-term, battery-free operation.
The K33 and K44 flow meters are designed to ensure maximum accuracy and durability, even in the most demanding environments.
Outstanding Accuracy: Measurement accuracy of the flow meters +/- 1% across the entire measurement range.
Simple Installation and Calibration: The devices are easy to install and can be calibrated on-site, minimizing downtime.
High Resistance: The maximum operating pressure is 10 bar, while the burst pressure reaches 30 bar, which guarantees safe operation.
Battery-Free Operation: Thanks to their purely mechanical construction, they do not require an external power source or batteries.
Suitable for Gravity Feed: Due to their low flow resistance, they can also be used for dispensing via gravity feed.
Multiple Application Areas: Ideal for mounting on pumps or for fuel measurement at fuel filling stations.
Direction Change: The device can handle four flow directions, providing flexibility during installation.
The main difference between the two models lies in their register capacity, allowing users to choose the model that suits their actual needs:
| Characteristic | PIUSI K33 | PIUSI K44 |
|---|---|---|
| Típus | Mechanical flow meter | Mechanical flow meter |
| Application | Diesel, HVO, XTL | Diesel, HVO, XTL |
| Partial Register | 3 digits (max. 999 liters) | 4 digits (max. 9999 liters) |
| Totalizer | 6 digits | 7 digits |
The detailed technical parameters of the K33 and K44 series flow meters ensure reliable performance:
| Parameter | Value | Note |
|---|---|---|
| Product Category | Fluid Transfer | Fuel |
| Fluids Handled | Diesel, HVO, XTL | |
