What is a hubodometer?

Hubodometers are measurement tools mounted to the wheel end hub of various types of rolling stock equipment, designed to count each rotation of the wheel, translate wheel size to a unit of measurement, and present the count on an electrical or mechanical display.

What is the purpose of a hubodometer?

Fleet operators and managers depend on hubodometers to accurately measure the distance or area covered by their equipment, often rented or leased. Common applications include maintenance scheduling, determining lease charges, and calculating cost per mile for rentals. Hubodometers are the least expensive, most accurate way to record miles or kilometers on a trailer or commercial bus.

How does a hubodometer work?

A hubodometer is mounted to the center axis of the wheel. As the wheel turns, forwards or backwards, the hubodometer enclosure also turns. However, the interior drivetrain of the hubodometer remains stationary, allowing it to count each revolution of the wheel and translate the revolutions into miles, kilometers, or acres.

7777 Series Mechanical Hubodometer

The 7777 Series Veeder-Root Mechanical Hubodometer is also known as “the original hubodometer” and boasts features such as:

• Records every revolution in both directions
• Hermetically sealed diecast zinc case with inert gas and doubled o-ring protection
• Precision shaft supported front and rear with needle bearings
• Specified by revolution per mile/kilometer— not just tire size, 300,000 miles/500,000-kilometer warranty (no time limit)
• A unique counterbalance design prevents orbiting — even on rough roads
• Magnifying crystals enlarge digits and angles for easier reading

Mechanical counters mount to the axle of a vehicle or trailer and count each rotation of the axle to track the total miles/ kilometers/ acres/ hectares traveled. The 7777 Series Veeder-Root Mechanical Hubodometer offers rugged and reliable operation for all applications. The die-cast zinc housing is hermetically sealed, filled with inert gas, and protected by a double O-ring.

As the vehicle axle rotates, the entire hubodometer housing rotates. However, an eccentrically mounted weight remains stationary inside the device. The weight, or magnet, always points down as the body of the hubometer rotates around it, counting each rotation. Contrasting wheels on the hubodometer faceplate display the readout in real time.

772 SERIES SLIM HUBODOMETER (link)

772 Series Slim Hubodometer Datasheet

The NEW Slim Hubodometer Series features a low-profile (23 mm), lightweight, and rugged design. The thinnest hubodometer on the market by 6 mm and weighs 25% less than competitors, allowing a tighter fit to the center of the trailer tire hub. This improvement enables more accurate and reliable mileage measurements to help protect the investment you have made in your trailer.

Easy to install, requires zero electronics, and begins working as soon as your trailer is in motion. This product’s housing is built with durable plastic and is hermetically sealed to protect it from environmental elements such as moisture, dust, and other particles. The Slim Hubodometer housing is also filled with nitrogen to help eliminate fog from the device’s face plate for more precise, reliable mileage readings.

Accuracy is imperative to sustain reliable maintenance routines, warranty coverage, and customer invoicing. Slim Hubodometer boasts an accuracy of +/- 2% depending on impacts such as outside temperature, inflation pressure, and vehicle/axle alignment.

• Unlike other solutions, the low-profile design of the Trailer Life Meter means that the product does not extend past the bulge of the tire.
• At less than an inch thick, you don’t have to worry about the Trailer Life Meter becoming damaged or destroyed by the regular usage of your trailer or towable vehicle.
