The LevelMatePRO Technology
When the LevelMatePRO product was conceived we made the decision to design and engineer the best vehicle leveling system possible within the contraints of technology. We designed the system to be easy-to-use and engineered it to be reliable and accurate. We are often asked what sets our product apart from other leveling systems on the market. We get a lot of specific inquiries about how our product compares to the Revoleveler. So we created this page to answer those questions and to shed some light on the engineering contained within the product. WARNING: If you are not a person who wants to know the technical details and just wants to know how our product compares to the Revoleveler, you might want to skip the next paragraph.
Explaining the engineering technology of the product requires some basic understanding of the digital accelerometer. Digital accelerometers are used in lots of products to measure angles and detect movement. You will find accelerometers in digital levels (the kind you get from the hardware store), video game controllers, smartphones and tablets, automobiles, aircraft and vehicle leveling systems just to name a few. Accelerometers are great for their intended purpose which is to measure movement or acceleration. They are also good for measuring angles but there is a fairly significant shortcoming with using them for this purpose and that is their lack of accuracy when subjected to variations in temperature. This issue can be overcome by the use of a temperature correction in the firmware of the product but due to the heat created in the process of soldering components to circuit boards and variations in components the correction must be done on each individual circuit board. For most mass produced products that measure angles like digital levels and unfortunately all other vehicle leveling systems, there is just not time in the manufacturing process or willingness to add additional cost required for temperature correction on each individual unit. Since we were committed to making the most accurate possible product we incorporated a digital temperature sensor, firmware based temperature correction and the necessary measurement and the data collection process required for this type of correction. Each LevelMatePRO circuit board is subjected to a range of typical operating temperatures. During this process the onboard firmware records angle deviations throughout the temperature range and stores them on each individual circuit board. This temperature correction data is then used to correct the angles measured by the system before they are used to calculate heights displayed on the LevelMatePRO system. When angles are measured by the system that are outside of the calibrated temperature range, the data is extrapolated to make the angle corrections. This temperature correction process is the only way possible to achieve 0.1° of accuracy when measuring angles with an accelerometer. Even though accelerometer components are rated at this 0.1° accuracy from the microchip manufacturer, by the time it is soldered to the circuit board the absolute best possible accuracy is 0.3°-0.4°. To give you some idea of what this means in terms of actual use for an RV, on the side-to-side leveling 0.4° is .67″ in height which is a noticeable amount when using the RV. In contrast, 0.1° of error on the side-to-side leveling would be only .17″ in height and wouldn’t be noticeable or affect the performance of the RV systems not to mention that most RV’ers don’t even have blocks or boards that are that thin. I believe in the case of RV owners, all would agree that being .67″ off level from side-to-side would be unacceptable. If you want the most accurate vehicle leveling system available then the only choice is the LevelMatePRO.
Since many of our customers inquired about the differences between the LevelMatePRO and the Revoleveler before they made their purchase, we thought it worth putting it on this page for all who might be interested in this comparison. Listed below are the major differences between the two systems.
- Accuracy. As explained above, the LevelMatePRO uses firmware based temperature correction for each individual unit. The other factor in accuracy of a vehicle leveling system is the use of angles to calculate the amount of height required to reach a level position. To make these height calculations requires both an angle and the length or width of the vehicle. LevelMatePRO allows the user to enter the exact width and length of their vehicle which, along with an accurate angle measurement, allows accurate reporting of each height requirement. The Revoleveler does not allow the user to enter the length and width of their vehicle so the heights being displayed by this system are using a preprogrammed width and length to calculate the height. And while most RV’s are 96″ wide, their length varies significantly. And because the Revoleveler can’t accurately report height requirements, especially in the front-to-back direction, the saving and recalling of the hitch position simply won’t be accurate enough to work properly. Since the point of a vehicle leveling system is to help achieve a level position with the vehicle, the fact that the LevelMatePRO does it more accurately than the Revoleveler may be all you need to know to make your purchase decision.
- Versatility. LevelMatePRO was designed to be used with both towable and driveable vehicles. So no matter if you have a popup, travel trailer, fifth wheel, Class A, Class C, Class B or Class B+ the LevelMatePRO system will work for your vehicle. The Revoleveler is only designed to be used with towable vehicles.
- Ease of use. LevelMatePRO is installed inside your vehicle one time and the only maintenance required is to replace the battery every 2 years or so. So when you want to use it simply get your vehicle in the desired location, get your smartphone or tablet out, start the app and see instantly how much height you will need to add and where it needs to be added. Using Revolevler requires a different process. Once your vehicle is at the desired location, you must exit your vehicle and attach the Revoleveler to the side of your vehicle, turn it on and then select the desired mode for side-to-side or front-to-back leveling. Unlike the LevelMatePRO, both side-to-side and front-to-back leveling information cannot be displayed simultaneously.
- Upgradability. The LevelMatePRO is a dynamic product. Since it uses a smartphone or tablet app that you download from the app store, we can add functionality and improve the product at any time by updating the app. The Revoleveler is a static product. The functionality that exists when you buy the product is all it will ever have. It’s functionality cannot be upgraded.
- Convenience. Since LevelMatePRO works with your smartphone or tablet and the LevelMatePRO unit remains installed inside your vehicle, there isn’t anything you have to remember to do in order to use it at anytime. Since the Revoleveler doesn’t remain installed on your vehicle, first you have to remember to bring the unit with you. It also has an internal battery that has to be charged, so you have to remember to do that as well. And of course each time you want to use it requires you to install it on the outside of your vehicle. Not a fun task when it is raining!
