I recently installed a 3rd ultrasonic tank sensor to a diesel
tank in addition to 2 existing sensors in water tanks
. I didnt notice any faults on the water tanks
readings before this so i assume they must have been OK.
I emptied my aluminium diesel tank and cleaned it out then calibrated it with water as it is an irregular shape. Well I tried about a dozen times and it just wont calibrate.
Crazy things started happening like the reading of the other 2 tanks would change while calibrating the 3 rd. A coupls of times a half full water tank read empty after calibrating the diesel tank, I had to reset the system. The best I achieved is a diesel tank reading that is not accurate or repeatable at all, while draining the tank at a constant slow rate the level drops in 30 ltr steps?
I have the pos and neg wires hooked directly to the batteries with heavy gauge wire with good soldered connections. I have read the manual many times over and shut down all other electrics while try to calibrate.
The strange thing is I have emailed Blueseas support twice in the past couple of weeks and no reply.
I will give them a call and see what they say.
