  • Overview


    Our exclusive H2F-SM Surface Mount Water Tank Gauge - RV, Caravan & Marine model - is suited more to the DIY aftermarket.


    Perfect if you have no space to install a display screen as screen does not need to be installed.


    Our senders and electronics are compatible with the majority of RV, Caravan & Marine water pumps and will even work with gravity fed systems.


    Installation is very simple. The sender is fitted to the hose line and there is nothing fitted to the tank.  This solves the problem of having to remove the tank, drill holes, remove filings, seal sender holes, ongoing cleaning/maintenance, etc.


    Ideal if you have multiple tanks or add more tanks at any stage you can simply change the programmed amount to suit your new capacity.


    The Topargee Surface Mount Water Gauge is a MUST for those loving the adventure of bush, free camping and boondocking as you will always know how much water is in your tank and you can plan your adventure more accurately.
