) which requires no holes in the tank with the sensors being attached on the outside. As posted by OttowW yesterday. You have not commented on this unit so far. Nobody else seems to have commented on this unit either.
do any of you guys out there have experience of the Gobius?
There've already been a few replies but I'll add the following as I just installed a Gobius Pro on a plastic holding tank in a Beneteau
41.1. I set it at a height corresponding to about 2/3 full, but that's a user choice. Also, if you're willing to buy more sensors, you can line them up vertically to have a more granular view. Several commented on exterior sensors being misled by buildup on the interior
of the tank wall. I don't believe this will be a problem with the Gobius Pro because it sends and reads back a vibration signature, influenced by the hollowness of the tank vs. detecting what's immediately behind the wall like some of the other technologies.
You can optionally monitor
the sensor with an included red/green LED that you wire to the sensor, via Bluetooth to your smartphone, or by connection to other third party monitors.
I tested the sensor by filling an empty tank with a hose through the pumpout port on deck
. The sensor reacted as it should when the fluid level reached it. So far so good with the dockside test. But the first field test on a cruise
wasn't achieved because the sensor detached and fell off! In spite of following the installation
instructions, the adhesive
just wouldn't hold.
In an earlier thread, someone suggested using acetone to remove the waxy substance often found on plastic tanks
. I'll try that next. An extra two-sided adhesive pad is included in the box. Does anyone have further suggestions on how to achieve the best adhesion?
Anyway, preliminary conclusion is it's a perfect fit for your need, not too expensive and easy to install. I even operate it off of a portable 12V rechargeable LION battery
pack. I didn't want to wire it into the boat
until fully tested. That works fine. It only sips milli-amps in standby mode, and consumes a few more when it actually senses, but you set the frequency you want and it only takes a few seconds each time.
One suggestion... if you use the provided LED monitor
, use male/female connectors that can be plugged and unplugged. On the sensor, put a male on the green lead and a female on the yellow lead and the opposite on the corresponding leads on the LED monitor. The reason for this is there's a documented hack needed if the device is locked to your smartphone and you need to reinstall the app whereby you disconnect the LED monitor, and "short circuit" the leads from the sensor. That's explained here
