Holding Tanks Level Monitors

[Larry W]

Our 2000 Royale uses Headhunter's system to monitor the fresh, gray and black tank levels. It is two systems, one for the fresh tank which also has the auto shut off feature and other unit that measures the other two tanks.
Over about a year all three quit working correctly. Headhunter sent me a troubleshooting guide. I followed the instructions and found by the instructions two of the tank sensors failed. I ordered two sensors for about $900 Lewbucks. One new sensor did fix the fresh water system. After the other new sensor was installed it did not work because the voltage to the sensor droped from the required 8 volts to less than 3 volts. I am now told the gauge unit power supply is bad. To end my troubles the new gauge unit is almost $400. I am not certain my third tank sensor is good. If not this adds another $495.
What system do some othe the other coaches use?
I have found a complete SeeLevel II by Garrett Technologies monitor system for a total of $465 for all three tanks plus battery voltage.
Does anyone have any experience with a SeeLevel II?

I have seen a SeeLevel guage on a Prevost coach I was looking at when shopping several years ago. As I remember it was a pretty simple system, with an electrical contact which was taped/attached to the outside of the tank, and I guess sensed the level via temperature or ??

Anyway, it worked fine. Instead of like some systems where you get 1/4 tank increments, this had a digital gauge which displayed in percentage.

I can't give you any idea of reliability, but the seller was really happy with the system.

Thanks for your input.

Larry,

Is there any reason why Headhunter cannot repair your units?

I have not turned my level sensors off in the 4 years we have had our coach and they have done very well except for one time when I had to recalibrate my holding tank sensor which took about ten minutes.

Larry, Alak and Lucia have a 2000 Royal with the same problems with the same system. You need to get with Al I know he had the replacement stuff in a box at home a couple of weeks back when I was there.

Jon & Joe
Thanks for the info. Jon, I have talked to Headhunter and they only seem interested in selling parts not repair. The display unit is potted so I doubt it can be repaired.
Joe I will contact Al. Thanks.
I am really leaning towards the SeeLevel unit as a complete system is the price of one Headhunter part in the system. The required work to get to the tanks to install the system is the only draw back. But of course what is a retired guy's time worth per hour?

Rich,

You can try one of the cleaners that is supposed to remove gunk from your sensors and see it that works.

Rich,

I assume the freshwater reading is correct. The Royale Phoenix system looks pretty simple. It has tubes placed in the tanks and remotely measures the pressure in the tubes. It's possible that the tubes are simply clogged. If so, it looks like you could blow them out. If blowing them out doesn't work, it's likely the sensor. If the fresh water one is working you could troubleshoot the others by connecting the gray or black tube to the fresh water sensor port and see if the freshwater sensor reads the level in the other tanks. I don't have the instructions, but I would guess you have to start with an empty tank after moving or disconnecting the hose to the sensors.

Good luck,

The level indicators that use air pressure to determine the level work pretty well. The biggest issue is the air line that goes sin the tank is prone to clogging. Try blowing it out with air. Do not blow air towards the receiver, the part that the air hooks to that determines the actual air pressure, the air pressure that is used to measure the level is only about 1 lb per foot of tank depth. Good Luck

If so, it looks like you could blow them out.

How do you blow them out? Do you have to remove the sensor from the top of the tank? Thanks!
