Vertical 5-hole fuel or water level tank sensor. 0-190 ohms European resistance range. Seal and screws are included.
I have a 100 litre over wheel arch water tank and I had not realised that the Victron Cerbo GX could do odd shaped tanks and had been looking for a 650mm sensor for some time, this was a great find and at a reasonable price. Shipping fast too.
Be aware you need to drill a hole at least as wide as the float as it does not come off.
