I've seen the vertical floats, the hinged floats, and the twin

Good sight glass....right there on the side of the tank next to the beer
cooler.


We've been running a hinged float sender for the last two seasons with
absolutly no problems once I had got a satisfactory initial setup. As
our tank is small and shallow, requiring the float arm to be cut rather
short, I had to ease the spring tension on the contact wiper and also
weight the float to get reliable operation. As we have a sail boat
aqnd expect to motor-sail if we have a deadline to keep, I mounted the
sender so the float pivots in a fore & aft plane on the centreline of
the tank. A large power boat might well be advised to mount the sender
transversely. A small planing power boat is probably going to find a
hinged float sender unsatisfactory.

I'd *love* to have a sight 'glass' but there is no way I could get
enough access to the side of my tank to either read the level or to
operate the essential shutoff valves top and bottom of the glass.
