Marsh Storage tank statistics:

Max height of water is 5 feet 7 inches
sensor is placed 5 inches above max height
tank diameter is 16 feet

Changes:

Mineral tub added for protection of electronics
Percent full and gallons added to site

Added to interface:

Question: how far away from the side of the tank can we operate?

Current version of sensor: MB7389-100

Reply from maxbotix on mounting sensor inside a tank:

Latter illustration suggests that we should mount the sensor 2' to 3' away from side wall if possible

Also: tank drop down to 8%:

How things are mounted at Marsh storage:

Setting for mounting at Twin Towers; distance from storage to the tower (where transmitter might go) is 13':

Marsh storage starting to refill

Questions:

make sensor box easy to mount
make solar panel easy to mount
something that can drill through for easy mounting
geometry of door -- on side? -- to access electronics ... or perhaps external antenna
actually, new satellite modem uses cable for connection anyway, can place the transmitter on case edge

Seems like perhaps the sensor has been affected by condensate ...

Some symptoms:

Ordered a Max 7850 'tank sensor' ultrasonic depth sensor from Digikey
Ordered another Rockblock 9602, from Sparkfun (9603 seems to be out of stock at Adafruit and Sparkfun)

Going to prototype using GPS and timer chip to send messages as close to 5 AM and a particular time in the evening as possible
