GPI 01A Series Turbine Fuel Flow Meter — 3–30 GPM, Aluminum Body, Battery-Powered Digital Display

The GPI 01A Series turbine fuel flow meter is a compact, battery-powered in-line meter that measures and displays fuel flow from 3 to 30 gallons per minute with both batch and cumulative totals.

This lightweight, aluminum-bodied meter combines a turbine measurement element with a digital display designed for mobile fueling and transfer tank setups. Built to read in gallons and to mount directly at the nozzle, the unit is engineered for gasoline blends up to E15, diesel blends up to B20, and kerosene. It offers intrinsically safe approval for hazardous locations and includes fittings and batteries so it’s ready to install.

How accurate and durable is the 01A turbine meter?

The turbine design delivers repeatable flow measurement for vehicle fueling and transfer tasks, while the aluminum housing resists corrosion from standard fuels. The display gives two totals—one accumulative and one batch—so you can track both per-fill amounts and lifetime usage.

• Flow range: 3–30 gallons per minute for typical fuel-transfer rates
• Two totalizers: 1 accumulative and 1 batch total for easy record-keeping
• Aluminum body for weight savings and fuel compatibility
• Digital readout powered by included AAA batteries for portable operation

What fuels and environments is this meter suitable for?

The 01A accepts common petroleum fuels and approved blended fuels but should not be used with water or chemical solvents. It carries FM intrinsic-safety approval for Class I, Division 1, Group D locations, making it suitable for many service, fleet, and construction fueling areas.

• Compatible with gasoline blends up to E15, diesel up to B20, and kerosene
• Not designed for water, antifreeze, or aggressive chemicals
• FM Approved as intrinsically safe for many hazardous locations
• Compact 12-ounce weight simplifies handheld or nozzle-mounted use

How easy is installation and what comes with the meter?

The meter mounts directly to the nozzle or in-line with the included fittings, and ships with the hardware needed for most common setups. A simple install gets the unit ready to measure immediately, and the digital display runs on two alkaline AAA batteries included in the box.

• Includes: meter, rubber bumper, two 3/4" reducers, one 3/4" x 1-1/2" pipe fitting, two AAA batteries, owner’s manual
• 1" female NPT thread standard for many pump and nozzle configurations
• Nozzle-mount capability for clear visibility during fueling
• Lightweight construction reduces strain when handheld

How will this meter fit into my fueling workflow?

The 01A is intended for portable fuel transfer and field fueling: it speedily reports gallons dispensed and helps you control inventory with batch totals. Use it on service trucks, transfer tanks, or any mobile fueling rig where reliable volume measurement and intrinsic safety matter.

• Batch totals for per-stop accountability, cumulative total for servicing records
• Handheld or fixed-mount use for flexible field workflows
• Clear numeric display positioned for quick readings at the nozzle

Who is this for: The GPI 01A Series turbine meter is aimed at fleet managers, service technicians, contractors, and anyone operating mobile fuel transfer systems who needs a lightweight, intrinsically safe meter that reports gallons with batch and cumulative totals. It’s ideal when you require a straightforward, ready-to-install flow meter that works with common fuel blends and fits into existing 1" NPT plumbing and nozzle setups.
