The Piusi MK325 flow meter is the latest generation, innovative electronic measuring instrument specifically developed for the extremely precise measurement of AdBlue® (DEF – Diesel Exhaust Fluid). This pulser flow meter guarantees standard-compliant, reliable performance, offering an ideal solution for logistics, mining, construction, and general garage applications where precise fluid dispensing is essential.
The MK325 model (part number variant F00476X20) brought significant improvements compared to previous versions, especially regarding safety and usability.
The MK325 pulser flow meter represents the pinnacle of Piusi's measurement technology, offering several key advantages:
Reduced Weight: Thanks to the optimized design, the device's weight has been reduced, which significantly facilitates installation and handling in mobile applications.
ATEX Certification (Zone 2): The most important safety improvement is the ATEX (Zone 2) certification acquisition. This enables the safe use of the device in potentially explosive environments, thus increasing operational flexibility.
MID Certificate: The device has the MID (Measuring Instruments Directive) assessment certificate, which ensures the credibility and suitability of the measurements for commercial circulation as well.
The excellent technical parameters of the MK325 flow meter guarantee long-term, reliable operation, even in industrial environments.

The Piusi MK325 is more than just a meter; it is a well-thought-out solution for optimizing fluid management:
A ±0.3% accuracy and ±0.2% repeatability ensures that the measured AdBlue® quantity always matches the actual consumption. This is critical for AdBlue®, as overdosing or underdosing can damage the vehicles' SCR (Selective Catalytic Reduction) system.
The device is capable of measuring the fluid flow in both directions. This feature is extremely useful in systems where fluid backflow or filling/emptying processes might occur in opposite directions, thus providing a comprehensive overview of fluid movement.
The MK325's pulsating technology minimizes wear on moving parts, significantly reducing the need for regular maintenance and operating costs. The durability characteristic of Piusi products guarantees a long service life.
The flow rate operating in the range of 5-35 l/min ideally covers the AdBlue® refueling needs of most medium and high-power diesel vehicles and equipment, whether from a depot filling station or a mobile tank trolley.
The ATEX/IECEx certifications (especially EX-M protection in Zone 2) make the MK325 one of the safest choices in industrial environments where there is a risk of presence of flammable vapors or mists. The MID approval certification ensures legal compliance for official billing.
The MK325 flow meter is the ideal choice in the following sectors:
Logistics & Transport: Precise tracking of AdBlue® refueling for large fleets.
Mining & Construction: Monitoring AdBlue® consumption for heavy machinery and construction vehicles, even under extreme conditions.
Fleet Management: Accurate measurement helps optimize AdBlue® inventory and reduce waste.
Industrial Sites: As reliable measuring units for permanently installed AdBlue® dispensing systems.
