All the existing level gauges on my
boat were VDO and on the 10-180 scale. I bought a new
engine instrument panel from TA
Diesel and it came with a new
fuel gauge but that gauge was on the US 240-33 ohm scale. So in that case I found it easier to replace the
fuel tank sender with a US sender.
In this case it was my water tank gauge. I have two gauges and 4
tanks. Each gauge has a 3 way toggle switch to select off or one of the two tanks monitored. In one of my tanks the sender was not reading right and in my infinite wisdom I broke it.
I did not want to change the gauge so I simply ordered a euro style sender to match the gauge and the other 3 tank senders.
Maybe one day I will hit the lottery and replace all the senders with
NMEA 2000 units and tie them into a N2K
network so I can see EVERYTHING my hammock on the bow...
