Frequently Asked Questions - Sun Company Inclinometer FAQs

What factors are important in selecting an inclinometer?

Inclinometers vary in range, accuracy, size and resolution.  So in order to choose a good inclinometer--one that fits your application well--it's important to consider several factors.  First, determine the maximum range of tilt you require, and select an inclinometer with an angular range equal to or slightly greater than your requirement.  Regarding accuracy, typically ball-in-tube inclinometers will increase in accuracy as the distance between "hashmarks" increases.  So it is advisable to select as large an inclinometer as is practical.  Regarding resolution, consider how "fine" a reading you require.  For example, should hashmarks occur every five degrees, every two degrees, etc.  Look for a SUN tilt meter with resolution to match your requirements.  Regarding size, please see our Inclinometers Specifications page for dimensional size of our tilt gauges.

How do I determine that my mounting surface is at "zero degrees" tilt, before mounting my inclinometer?

Move your rig to a flat, level area.  Then using a carpenter's level or other means, level the member to which you will attach your SUN inclinometer.  When mounting the tilt indicator, make sure the indicator ball is aligned with the "0" mark on the inclinometer.  If drilling holes in your SUN tilt indicator for hardware mounting, make the holes slightly larger than the threaded fasteners, to allow some "play" in the positioning of the tilt gauge, before final tightening of the mounting hardware.

What is important in mounting an inclinometer? How do I mount an inclinometer?

It is important, for accurate readings, that your SUN inclinometer (1) is mounted to a true vertical surface, (2) operates within the temperature range shown on this website's Inclinometer Specifications page, and (3) operates in a vibration-free environment.  Vibration can cause static electricity, which can inhibit movement of the indicator ball. 


If mounting your angle gauge with the provided pressure-sensitive tape, the mounting surface should be at or above 60 degrees F (16 degrees C).  If mounting with tape, clean the mounting surface with Isopropyl alcohol or other grease cutting cleaner, so the surface is free of dirt, grime, oil and grease.  Surface must be dry.  Mounting member must be at true horizontal.  Once the inclinometer is in the desired location (with indicatorball at zero), press the tilt gauge firmly against the mounting surface to set the adhesive.

Where should I mount my SUN inclinometer?

Select a mounting location so that your SUN inclinometer will be readily visible from the cab of your vehicle or rig.  If mounting outside the cab, get help from a second person.  While the operator is seated in the cab, a second person can move the inclinometer until it's at the location most easily viewed by the operator.

How can I convert angular degrees to percent slope, and vice versa?

There are several website than offer a free, easy to use "degrees to percent slope" calculator, and a "percent slope to degrees" calculator.  For example: and
