Updating holding tank sensors

[Bob Lawrence]

Hi group,

Just to let you know about an upgrade I did to my holding tank
sensors. Took maybe 3-4 hrs total to do this.

Like most of us, the sensors (probes) that our rigs came with are
prone to getting fouled. I found in the first 4 years of ownership
that I couldn't rely on the sensors to give me an accurate reading.

I found the Micropulse system while looking around in the Prevost and
Newell sites.

What these are, are sensors that are mounted as low in the sidewall
of the tank as possible using a 3/4 spin in or the flat sensor
adaptor. The flat adaptor is the one I used. The adaptor required
drilling a 5/8 hole in the sidewall of the tank. Put some silicone
glue to the bottom of the adaptor. Also used #10 x 1/2" stainless
steel self tapping screws to attach the adaptor to the sidewall. I
then wrapped the threads of the sensor using Teflon tape and
installed the sensor by screwing it in the adaptor. Just tighten by
hand.

The sensor is connected to the monitor using a 4 conductor flat
modular phone cable supplied.

I put the monitor alongside the fridge inside. Had to run the wire
down behind the fridge and thru the floor to the sensors.

I put a sensor in the grey and one in the black tank. The monitor can
also handle fresh water and LP sensors. I didn't feel the need for
these.

My findings after using this system fulltime for over 8 months now
are great!! When I push the buttons (or can leave on fulltime),after
calibration it has proved to be very accurate. We love it!!

To calibrate after install, you of course have an empty tank (better
before you drilled the holes LOL!!)you push a button for the empty
reading for each tank. Then you fill the tanks and take another
reading. The minicomputer in the monitor calculates the areas in
between and registers on the display.

The unit has a 5 year warrenty and are used on the high end rigs now.

The nice thing about these sensors is they use liquid pressure to get
a reading so there is no probe to foul. Never need cleaning.

Finally an accurate reading!!

Any questions, please ask...
