The only exception I’ve seen so far was a 8-25% wobble in the starboard fuel tank when it was down to 3.5-inches and the boat was rolling mildly, and I seem to have improved that with another level guesstimate. What I’ve learned so far is that all the Wema senders, even the one submerged in Black Water, are remarkably consistent day-by-day for a tank that hasn’t been used and seem to make good sense about what is used. That means I’ve already been able to set tank percentages based on string measurements made at the same time and when I find a very patient fuel dock I’ll be able to set or edit as many points as I want in terms of gallons.īut equally important, I think, is that this live calibration feature has let me easily observe the sender states. What I love is shown in the bottom window where I am about to set a calibration point using “live data” from the sender. I should do some reading though and I already see that there are impressive capabilities I haven’t tried yet, but let’s focus on the tank configuration screen above.

It seemed daunting at first but I’ve now managed to configure a few modules with it and I’ve hardly cracked the manual.

Then there was the CZone Configuration Tool, which is a Windows PC program that connects to the modules via a USB CAN Adapter. In the photo I tried to show how the module is designed so that you can wire up the gasket and terminal strip away from the module and then put it all together in one easy move. I just snipped the blade connectors off the tank and -12v wires that once went to the Wema gauge inserted them into the SI’s removable terminal strip, added a NMEA 2000 drop to the boat’s SimNet network and that was about it.

The hardware install could not have been easier. I intended, of course, to replace the Wema gauge or try something else, but didn’t actually do anything until using the gauge became a matter of jiggling the on/off knob just so and then it died completely early in the trip north.Īlso on the (very long) to-do list was testing some BEP CZone modules, including the Signal Interface which is purportedly capable of reading 240-30 Ohm tank senders like the Wemas. I also think that the tanks are rectangular, which would make a linear measurement equate well to volume, though I avoided assumptions that could get me in trouble. Yup, I started using a weighted line to occasionally measure fuel tank levels and felt fortunate that the boat’s short, straight filler hoses make this easy and fairly accurate (I think). That got my attention and though the readings got consistent again once we started bouncing around a bit yours truly also got more consistent about logging miles, engine hours, and tank in use, and I took further measures, so to speak… Suddenly the fuel tanks showed significantly different readings than they had the day before even though the engine had not even been run. The situation took a bad turn last September, just before I headed south. The Poop Tank in particutlar was highly inconsistent, staying at “0” for unreasonable periods and sometimes jumping to “4/4” seemingly overnight, but didn’t it make sense that even a specially protected sliding level sensor might fail after so many years in those conditions? If it works don’t fix it, right? But in fact it never worked very well I just didn’t realize it. Aside from the Volvo Penta engine panels the Wema Tank-level Indicator is the only remaining gauge from when I bought this boat in 2009 and it was probably there when she was launched in 2000.
