Advanced RV Tank Monitoring

Traditional tank monitors have a reputation for being unreliable. Only a few sensors are installed inside, meaning that they usually only measure in quarter increments and can send false readings if they get dirty. When you're keeping an eye on how much fresh water you have, the difference between 25% full and empty means a lot, and that inaccuracy can be a problem.


The SeeLeveL tank monitoring system uses technology that can sense fluid levels from the outside of the tank. The sensors' flexible circuit board sticks in place and measures along its entire height. This makes it accurate in single-digit increments.

Awesome product!!! Now I can really see how full each of my tanks are!

These sensors are so much better than the internal probes because they don’t get gunk on them. You can set the sensors on the outside and the positions that you want and it reads by percentage. I would definitely buy them again.



by:

The installation of these tank level sensors was straight forward. The video from Garnet Instruments was very helpful. I had to order a cable from FireFly Integrations to connect the 709 panel into the CAN bus system in my RV. My tank readings are now more accurate and not subject to interference from debris inside my tanks. Very happy with this product.

It is a Christmas present so I haven’t opened it yet.

We put the SeeLeveL system in our camper van about a year ago, and it has been a game changer for us. Before installing the system we only had a visual check on water level, by looking at part of the tank under the seat bench in the back of the van. It was inconvenient and because the tank is only semi-translucent, not always very accurate. The monitoring system remedied that. In addition, I can now monitor tank level while filling the tank by watching percent full from the back of the van... filling the tank used to be a two-person job. Finally, we have a 5 gallon gray water tank under the sink... we attached one of the sensors to the gray water tank, epoxied it for extra support, and wired the sensor to the system using flat electrical connectors so that it can be easily removed from the van for disposal of the gray water. It works like a charm, enabling us to monitor both fresh and gray water in the van. It was a simple installation, and I highly recommend the product.



by:

An excellent system! Simple reason: designed and Made in Canada! To date, "etrailer" was a great source for the various items required for our production line and we did not mind buying a Canadian product in the US. But obviously, in light of recent political events, this practice is no longer logical nor viable. Canadian RV folks and Vanlifers, take note. This item, and most of the others, are available in Canada.

Works just like it is supposed to



by:

Great product. They work very well.
Would
purchase again.



by:

Package arrived ahead of schedule - thanks.

We’ll have the see Level system installed by professionals.

All appears to be good.



by:

Work great, seem to be accurate



by:

I still have not managed to install the sensors. The side walls of the gray and black tanks are stepped, making the installation of the sensor strips a bit more complicated (vs, tanks with vertical side walls). Also I'm a little hesitant about how to connect the wiring.

I think (hope) it will be great when I'm done, but the process is more complicated than I expected.

  • What is Needed for SeeLevel Propane Tank Monitor to Function
    Hey Dean, so SeeLevel has a RV Holding Tank Monitor that includes ability to monitor propane tanks with the part # SE34VR but the gauge needs to wire to the remote sensors on the LPG tank. If there's no wiring there currently it wouldn't work without a remote sensor setup. See attached picture to see what that looks like normally. Its not super uncommon for there to be issues with black water sensors as they tend to foul out pretty easy. What's great about the SeeLevel systems is the...

  • How Do the SeeLeveL RV Holding Tank Monitoring Sensors Work for Propane Tanks
    With your trailer not currently measuring propane levels, I would recommend going with the SeeLeveL RV Holding Tank Monitoring System # SE39VR which comes with the water pump switch. The reason for that is because the SeeLeveL RV Holding Tank Monitoring System # SE59VR which can monitor propane is only going to work if your propane tank already has a gauge with wired sensor. This is because the sensors in these kits will not work with metal tanks, including propane tanks. These prewired...

  • Differences Between SeeLeveL RV Holding Tank Monitoring Systems # SE33VR and # SE39VR
    The 2 differences between the SeeLeveL RV Holding Tank Monitoring Systems # SE33VR and # SE39VR is the # SE33VR has the bluetooth capability and it can also integrate into the propane tank sensor. Neither of these systems will integrate with the Firefly system you have so you will need to install the new panel and sensors. Before you go ahead with the new sensors have you tried using any Valterra Sensor Power Sensor Cleaner # V22011. It could simply be the sensors inside the tanks may...

  • Recommended Sensor System For Determining Water Tank Levels
    While we don't carry any sensor system that would be able to communicate how many gallons are in your tank/how many were used we do offer the SeeLeveL RV Holding Tank Monitoring System # SE39VR, which has eight sensors for a more accurate reading. These sensors have a double-sided tape backing that will allow you to stick them straight onto the water tanks for an easy installation. Depending on the size of the tank you can add on more sensor strips or cut off sensors to make it fit. You'll...

  • Where Is The Power Source for External Tank Sensors
    The SeeLeveL RV Holding Tank Monitoring System, # SE39VR operates from a 12 VDC power source. The installation consists of mounting the display inside the RV, cutting and fastening the senders to the sides of the holding tanks, connecting wiring, and programming the display. The red wire is connected to +12V power input to monitor, black to ground, blue to tank sensors and white to pump indicator.

  • Which SeeLevel Holding Tank System For 5th Wheel
    This really depends on if your 2022 Alliance Paradigm has an RV-C, multiplex wiring system which usually connects to a central control panel. If you have that, then use the SeeLeveL RV Holding Tank Monitoring System # SE99VR. If you don't have that wiring system in your RV then go with the SeeLeveL RV Holding Tank Monitoring System # SE39VR.

  • Are The SeeLevel 709-P3 Monitor And 710-AR Sensor Strips Available
    Hey Ed, The SeeLevel Tank Monitor 709-P3 can be purchased under part # SE44VR and the 710-AR sensors can be purchased with part # SE88VR. These are all sold individually so you would need to get three of the # SE88VR to have one for each of your water tanks.

  • Availability of SeeLevel System that Has Levels for Fresh, Gray, and Black Water
    That part number corresponds with a SeeLevel system that has sensors for a fresh, gray, and black water tank like the part # SE39VR but we do not have the version that has the NMEA2000 interface.

  • Holding Tank Sensor System Needed For An RV
    Hi Miguel, Are you saying you're looking for a SeeLevel RV Holding Tank Monitoring System like the # SE39VR? If so, you'll want to measure the height of your tanks to ensure the 12" sensor strips are the right size or if you'd be better off switching to the 9" strips. You'll also wan to determine how many sensors are needed/what functions you want the monitor to have. For example, the # SE39VR can monitor up to three tanks (fresh, grey, black) and has a switch for the water pump to turn...

  • Recommended RV Holding Tank Monitoring System
    Hey Teresa! I am not sure what monitoring system you have on your 1995 Coachman trailer but unless its a recent aftermarket addition we are not going to have any replacement parts for it. The best I can do is offer you a replacement. I recommend the SeeLeveL RV Holding Tank Monitoring System item # SE39VR. The SeeLeveL item # SE39VR uses technology that can sense fluid levels from outside of the tank. The sensors' flexible circuit board sticks in place and measures along its entire height. If...
