Its time!!!
The RV industry addresses one of the top 4 peeves of RVers!
Inaccurate and unreliable tank level monitors


The solution has arrived with the SeeLevel range of tank monitors from Garnet Industries


Field proven technology with thousands of successful OEM and after-market installations
 
High reliability reduces warranty costs and improves customer satisfaction
 
Advanced sensing technology: the tank sensor does not foul or need calibration, and the lever accuracy is with 1/2 inch!
 
A single wire bus connects all three senders to the display, saving wire and avoiding connection errors
 
Simple installation, compact size, full features, extensive diagnostics, low price: the choice is obvious!


The History of the SeeLevel RV Gauge
 
A few
weeks after Garnet's marketing manage, Don Shapansky, purchased a new high end fifth wheeler, the tank gauges began to fail. As Don travelled full time through camp-grounds, and talked to other RV owners, it became apparent that this was a widespread problem with no solution. Not only was this nuisance, but substantial flood damage to RV's was also occurring due to the primitive water and waste management systems
Since Garnet was already a successful company in level gauging for the industrial market with unique and reliable products, it was a logical step to address the RV market with a whole new approach to tank gauging. The marketing and engineering teams at Garnet collaborated to determine the features that this new gauge was to have. They were (and are) as follows:

                         1. High reliability, the gauge had to perform as well as new for many years                                    
 
                         2. High accuracy, much better that 1/3 or 1/4 tank that was current in the market                          
 
                         3. Easy to install, since it would be aimed at both end users and manufacturers                           
 
                         4. Attractive user interface, to fit the decor of both entry level and high end RV's                          
 
                         5. Reasonable pricing to make it accessible to the entire industry                                                      
 
                         6. Built in diagnostics, so that if a problem did develop, it could be found quickly and repaired
 
                         7. Simple to operate, so that any RV owner would feel confident using the system                       


Those criterion led Garnet to determine the appropriate technology for the system:

     To achieve reliability, the sensing had to be done from outside the tank, since any internal components exposed to
        the waste would get fouled. A special, high strength, low surface energy adhesive was sourced to ensure long term
        adhesion to the tank. No effort has been spared to ensure a reliable product. An example: test tanks were lined with a
        variety of nasty materials to simulate waste build-up, and sender parameter were measured and documented using
        custom built test fixtures  
     To achieve accuracy, the system had to be digital, since analog systems drift and need regular recalibration. The
        digital capacitance system used is self-calibrating, with accuracy based on the physical position of the sender
        components, not on the characteristics of the tank contents. To display an accurate quantity, high resolution LED bar
        graphs or 3 digit numerical readouts are used to show percentage of full
      To achieve ease of installation, the tank sender had to be readily configured to a variety of tank heights, which dictate
        a simple "cut to required length" approach. No additional wiring could be required, so the senders had to receive
        power and communicate over a single wire. The display panels had to be compact to fit into existing gauge spaces
 
     To achieve low cost, advanced manufacturing techniques were required. New manufacturing equipment was
        obtained, and new assembly techniques were developed
 
     To achieve advanced diagnostic capability, an advanced microprocessor based system was required. Fully 50% of the
         software in the system is dedicated to diagnostics


After much thinking, discarding and refining of ideas, research, testing, field trials, years of continuous improvement and
expansion of the model line, the Garnet SeeLevel line of RV gauges stands as the ultimate solution to RV tank gauging. Nothing else even comes close

And the process continues. Future improvements include more advanced RV system automation, remote communication
interfaces for the upcoming RV diagnostic bus, and more models to fit every coach and tow-able niche
