Description

The PIUSI K150 Mechanical Flow Meter is the perfect flow meter for environments where a high flow rate is necessary, such as in industries that run vehicles with big tanks, etc. The PIUSI K150 Mechanical Flow Meter is ideal for supplying machinery and heavy vehicles to the agricultural industry, as well as trucks in the logistics sector and off-road vehicles in the construction sector.

Flow rate range from 25 to 150 l/min
The PIUSI flow meter range satisfies every flow requirement:


Precise, a basic feature
The K150 ATEX high flow mechanical flow meter is equipped with an oscillating disc reading system that guarantees 1% accuracy in measuring the fuel delivered at medium flow rates.

ATEX IECEx certified
The K150 mechanical flow meter meets the ATEX/IECEx requirements for the use of materials in potentially explosive atmospheres. The K150 ATEX can therefore be used for monitoring the flow of explosive liquids such as petrol and kerosene.

Up to 33% less pressure drop
The K150 high capacity mechanical flow meter differs from other meters on the market, because it ensures up to 33% less pressure drop.

Resistant and reliable over time
At constant flow rates, the K150 high flow mechanical flow meter is accurate and reliable. Equipped with a 4-digit volumetric counter, it is simple to use easy to calibrate.

The high resistance to high pressures and wear is guaranteed by the robust aluminium body.

Compatibility with other fluids
Diesel, B7, B20, Kerosene, Petrol, Petrol E20, Avgas 100/100LL, JetA/A1, Aspen 2/4

Not suitable for measuring products for the general public.

What Is a Digital Fuel Meter?

A digital fuel meter is a precision instrument designed to measure and display the volume of fuel dispensed from tanks, pumps, or fuel transfer systems. Unlike mechanical meters, digital fuel meters use electronic sensors and LCD or LED displays to provide accurate, real-time readings of fuel flow.
Common Use Cases:
Digital fuel meters are commonly used in:
  • Service stations
  • Mining and construction refuelling setups
  • Agricultural fuel trailers
  • Workshops and fleet depots
These meters are compatible with a range of fuels including diesel, petrol, kerosene, biodiesel, and even AdBlue, depending on the model. They are often installed inline and can be paired with electric or manual pumps.

How Accurate Are Digital Fuel Meters?
Digital fuel meters are highly accurate, typically providing measurement accuracy within ±0.5% to ±1.0%, depending on the brand and calibration. This level of precision makes them ideal for commercial fuel dispensing, where exact measurement is essential for:
  • Inventory tracking
  • Billing accuracy
  • Regulatory compliance
Factors That May Affect Accuracy:
  • Fuel viscosity and temperature
  • Flow rate and pressure
  • Calibration and maintenance frequency
Leading digital meter brands offer consistent and repeatable results, which is crucial for industries that require traceable fuel usage and accountability, especially in sectors such as mining, transport, and agriculture across Australia.

Can Digital Fuel Meters Be Calibrated?
Yes, digital fuel meters can and should be calibrated periodically to maintain accuracy and meet industry standards—particularly in commercial or regulated environments.
Typical Calibration Procedure:
  1. Use a known volume container (e.g. 20L test bucket)

  2. Dispense fuel through the meter

  3. Compare the meter reading to the actual volume

  4. Adjust calibration settings using onboard buttons or software (depending on model)

Some advanced models offer automatic calibration features or external calibration ports for easier servicing.
Why Calibration Matters:
Regular calibration ensures:
  • Accurate fuel tracking
  • Prevention of billing disputes
  • Compliance with Australian measurement standards and environmental regulations
