Fuel Flow Meters

Overview

Fill-Rite 901 Series meters are three-digit mechanical registers capable of measuring in gallons (Gal) or liters (L) depending on the model. Built from durable aluminum or nickel-plated aluminum housings, these meters deliver consistent performance for a broad range of fueling applications, including agricultural, fleet, and industrial refueling.
