A while back a Love Your RV! reader named Jim clued me into an inexpensive device from a company called Rainwave. The gadget measures the flow of water displaying the volume in gallons or liters.

He uses it when flushing his waste tank so that he doesn’t overflow it. Pretty cool little tip. So, I picked up one from Amazon to give it a try. In this video, I show the Rainwave water flow meter in action and talk about a few other applications for it around the RV.

I use one made by Gardinia when filling our freshwater tank to the exact amount I think we’ll need for traveling so that I’m not carrying too much weight. I figure approximately 5 gallons per day per person which allows for navy showers every other day.
Cheers!
I have a total of 160 gallons of fresh water capacity (two 80 gallon tanks linked) and I almost always over flow it when Im about to go on a trip. I don’t trust the little red lights inside on the panel, so I really don’t know when I’m approaching full. Then I get distracted and forget…lol. I purchased the reviewed flow meter via Ray’s link and received it today! Now I should have a decent idea when I’m getting close to full. Then I’ll know the exact capacity of the tanks. Thanks, no more flooded wet bay, lol.
This is a great idea… I use a more robust meter that I found at flows.com. It has 2 totals… one that resets, and lifetime total. I also do not trust the meters and level sensors that are in my tank, so I also use another meter that was recommended to me. The DigiFlow 8300 T. This meter you set the “full” volume when you fill the tank (use the value from the DM-P meter when filling.) Then the meter counts down as you use water… when you get to ZERO, there is an audible alert. Actually, I typically set this to 5 gallons LESS than the real amount, so I get the alert early… BEFORE I run dry.
