Choosing the Right Fuel Bowser or Dispenser
A fuel bowser sits between your bulk fuel tank and the vehicles or machines you refuel. The right unit depends on whether you need fiscal-grade metering, what you are dispensing, and how fast you need to fill.
NMI approval. If you sell fuel, sub-meter for cost recovery, or invoice on the litres dispensed, the bowser must be NMI-approved (National Measurement Institute pattern-approved) and recalibrated annually by a certified technician. The SANKI range carried here is NMI-approved out of the box.
Bowser vs dispenser. A bowser is the term used for a self-contained refuelling unit that includes the pump, meter, hose and nozzle in one cabinet. A dispenser is the broader category that includes bowsers plus tank-mounted dispensing units, retail-style fuel pumps and high-flow truck-stop nozzles. In practice the words get used interchangeably; the spec that matters is flow rate, hose count, and approval class.
Flow and hose count. Single-hose bowsers (80-130 lpm) suit one-vehicle-at-a-time refuelling and quick fleet turnaround. Dual-hose dispensers add a second nozzle so two vehicles can fuel at once: useful at peak depot times and at sites where you split diesel and AdBlue dispensing into one unit.
Fluid. Standard SANKI bowsers handle diesel directly. Petrol bowsing requires an EX-rated unit and a hazardous-area-classified install per AS 1940. AdBlue dispensing needs a stainless-internal pump and Viton seals: don't run AdBlue through a diesel-spec bowser.
