Propane tank monitor

We made the switch from a motor home to a TT. The motor home had a propane tank monitor along with the tank and battery monitor. With the TT we have no way of knowing how much propane we have left. I have searched for some kind of monitor for the tanks but can't find one. How do you know how much propane you have?

    Thanks Bisquit. I was confused about the red and green things and how they worked. I think until I get used to it I will close one tank valve until the other runs out. I will get an idea how long a single will last. I have two 30 pound tanks. I figure that is nearly as much propane as my motor home tank held. I might check into Pine5008 idea also.


    30#....7.5 gallons (figure on 7 gallons so 14 total)

    We FTd for 7 yrs. and I always left one valved out after I ended up with 2 empty cylinders :S
    Out of sight out of mind........so for me having one go empty was a gentle reminder.

  • When one tank empties, switch to the other, and refill the MT sooner or later depending on your use. Use labels if necessary.
  • Try this out:

    Cheap and easy
  • Do you have dual propane cylinders?

    Valve one in service......flip lever so it points to that cylinder.

    When that cylinder goes empty..regulator will swap to other cylinder/indicator flag will turn from green to red. Valve in other cylinder--flip lever to it.

    Valve out empty cylinder, remove it and go get refilled.


    OR valve both cylinders in..........check indicator flag routinely cause when it turns red BOTH 1st cylinder is empty/regulator has swapped to 2nd cylinder.
    Flip lever to 2nd cylinder.flag goes from red to green BUT----2nd cylinder may be full/partially full/almost empty cause you won't know when it was swapped to.

    After a while of using them you will get an idea how long YOU can go on one based on YOUR type of usage.

    We typically go 6 weeks on one of our 30# cylinders.
