We have just finished
fitting one to our Tvan and are very happy with the results. The sender unit can
be fitted to almost any water tank, provided it is not more than 280mm in depth,
by any handy person with moderate skills. The sender & gauge we fitted was
developed by RV Electronics in SA and it was obtained from a local caravan parts
retailer for $59.50. Additional sender units & 2.5m wiring extensions are
available at a moderate cost.
There are two variations of gauge available, an oval
one and a square one. We chose the square as it was the shape required for where
we wanted to install the gauge.
Gaining access to the water tank on our Tvan was a
challenge because aluminium drawers are fitted over the hatch in the floor that
enables access to the plastic water tank. However, persistence and care won out.
On the positive side though, it made for a great place to fit the gauge on the
blank between the drawers and the wall.
The only other obstacle encountered was the wall
thickness of the tank. This inhibited the correct operation of the supplied self
sealing grommet which popped out when tightened. This was easily overcome by
using a Stanley knife through the drilled hole to trim the burr inside the tank.
By taking some additional plastic as well as the burr it had the effect of
thinning the tank wall and the grommet then tightened and sealed correctly
without any problems. The rest was straight forward.
