GPI Turbine Fuel Flow Meter 01A Series — 3–30 GPM, Aluminium Body with Battery Digital Display

The GPI 01A Series Turbine Flow Meter is a compact, battery-powered aluminum fuel meter that measures 3–30 gallons per minute with both batch and cumulative totals for safe, portable fuel transfer.

Built for field fueling and transfer tanks, this turbine-style meter combines a lightweight aluminum housing with a backlit digital display so you can read gallons quickly while handling gasoline (up to E15), diesel blends (up to B20), and kerosene. The unit mounts directly to the nozzle and uses a 1" female NPT inlet; it ships with reducer fittings and batteries so it’s ready to install out of the box. FM approval for intrinsic safety makes it suitable around hazardous fuel vapors within Class I, Division 1 Group D environments.

How accurate is the GPI 01A Series meter for everyday fuel transfers?

This turbine meter gives repeatable readings across its 3–30 GPM flow window, with a digital register for immediate batch counts and an accumulator for lifetime totals. It’s designed to provide reliable field accuracy for trucks, skid tanks, and mobile refueling rigs.

• Flow range: 3 to 30 gallons per minute (GPM)
• Two totals: 1 batch (resettable) and 1 cumulative (non-resettable)
• Digital display shows gallons; easy-to-read numeric output
• Lightweight 12 oz aluminum body minimizes add-on weight to hose or nozzle

What fuels and environments can this meter handle safely?

Use the meter with common vehicle and equipment fuels—gasoline blends up to E15, diesel blends up to B20, and kerosene. It is not rated for water or aggressive chemicals, and the FM intrinsic safety approval addresses use around flammable vapors when installed correctly.

• Compatible: gasoline (≤ E15), diesel (≤ B20), kerosene
• Not for water or chemical service
• FM Approved: intrinsically safe for Class I, Division 1, Groups D
• Aluminum construction resists corrosion in fuel service

How easy is installation and day-to-day operation?

The meter mounts directly to most nozzles and includes the common fittings and batteries needed to start measuring right away. Its compact footprint and simple controls mean minimal disruption to existing fueling setups and quick readings during each transfer.

• Includes: digital meter, rubber bumper, two 3/4" reducers, one 3/4" x 1-1/2" pipe fitting
• Supplied (2) AAA alkaline batteries and owners manual for immediate use
• Mounts on nozzle for in-line, easy-to-see readings
• Compact weight: approx. 12 ounces for portable use

What maintenance and support should I expect for this fuel meter?

Routine care is straightforward: keep the turbine and inlet free of debris and check seals periodically. Replacement parts and full specifications are available through GPI and authorized resellers to ensure ongoing accuracy and safety compliance.

• Simple maintenance: visual inspection and clean filter/screens as needed
• Replacement fittings and parts available from GPI distributors
• Owners manual included for troubleshooting and set-up guidance
