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.

Key Features & Benefits

  • Rugged Mechanical Design: No electronic components; purely mechanical register for reliable operation in remote or harsh environments
  • Easy-to-Read Meter Face: Large, 3-digit roller counter for straightforward batch measurements
  • Simple Maintenance: Field-serviceable internal components with accessible calibration points for quick flow adjustment
  • Versatile Fluid Handling: Broad chemical compatibility for petroleum fuels and select water-based fluids
  • Compact Form Factor: Easy integration with pump units, fueling nozzles, or inline mounting with minimal space requirements

Typical Applications

  • Farm & Fleet Fuel Transfer: Diesel tanks, tractors, heavy machinery fueling
  • Commercial Fuel Pumps: Gasoline dispensing in small-scale distribution setups
  • Construction & Mining: On-site fueling stations for heavy equipment (within stated flow/pressure specs)
  • Non-Potable Water: Select models for irrigation, dust control, or industrial water transfer
  • Portable Transfer Tanks: Installation on mobile fuel trailers or service trucks
