Get reliable, straightforward fuel measurement with the GPI M30 Modular Mechanical Fuel Meter. Designed for use with fuel transfer pump systems operating from 5 to 30 GPM (19 to 114 L/min), the M30 provides accurate mechanical flow measurement without requiring an electronic display or battery power.

Accurate Mechanical Fuel Measurement

The M30 uses a proven nutating-disc measuring system to translate fuel flow into calibrated units. It provides typical accuracy of ±2% across its rated flow range, making it well suited for monitoring fuel dispensing and transfer operations. The meter is factory calibrated using diesel fuel, with field calibration available for other approved applications.

Quick-Fit Modular Design

Installation is made simple with the M30's Quick-Fit modular mounting system. The meter attaches to compatible GPI fuel transfer pumps and modular accessories using a straightforward four-bolt connection. NPT and flange connection options allow flexible installation on compatible threaded pump outlets or GPI modular products.

Durable Construction

Built with a durable aluminum housing, the M30 is designed for demanding fuel-transfer environments. Its magnetic-drive design replaces a traditional driveshaft and seal, helping eliminate potential driveshaft leaks while providing a low-maintenance mechanical solution.

Designed for Petroleum Fuels

The GPI M30 is intended specifically for measuring thin-viscosity petroleum fuels and is designed for use with compatible pump systems rather than gravity-flow applications. Approved fuel applications include gasoline blends up to E15, diesel blends up to B20 and kerosene, subject to the manufacturer's specifications.
