View Full Version : Moisture Sensor per zone

Anyone ever retrofit a system to have a moisture sensor on each zone? I have a condo complex looking for this solution (21 zones on 3 separate controllers). I don't know who their original contractor was (neither does the condo board); everything appears (can't see it run...blown out for winter) to be ok materials (Hunter ), although the Hunter distributor around here sells to anyone (i.e. almost any hack job one step above Home Depot will be Hunter materials, not saying that all Hunter installs here are done by hacks though).

My supplier catalogs are blank for moisture metering gear; all that normally gets done around here is rain sensors. Any thoughts?

First of all, buy a 10 yard dump truck & have the homeowners fill it with cash.
Then you are ready to proceed: Remove & junk the comtrollers, they cannot
handle so many meters. Now go down to the sprinkler store in town, (the
one located next to the Mercedes dealer) & check the specs & prices for
either Rain Master or Calsense clocks. I don't have my Calsense spec book,
I'm sure Kiril will hop in, but Rain Master can handle 12 sensors, these operate via the 12 programs available. While you're at it, buy a weather
station so you can balance ET & wind with the moisture sensors. Then, budget
a entire season, at least a hour a week, to getting these very tricky parameters adjusted & proven. Having a Rain Master or Calsense remote is
a given. Throw in a Data Industrial flow sensor to protect the system while
you're at it & lastly, take pics & let us know how many years it will take to
amortize the cost vs. monitoring with a standard moisture probe & adjusting from those readings.

:rolleyes: Oops, forgot..buy the central system software & the baddest computor available.

hmmmm that wasn't the answering I was looking for...lol

No one manufacturers a probe that can sit in the ground and be wired into a valve? Think of a rain sensor..just need a probe and wire one into each valve instead of the common.....

Think about it..the valve would have to have a "window" of operation, unlike
rain sensors that short the common for the entire system, you would have
to have separate commons for each valve..with no water flow after being
shut down, the solenoid could (& will) fry...get the dump truck.:)

maybe I'm missing something here...

Instead of shorting the common, why not short the control line?

Here is the say all end all...

After whatever price you tell them will will then decide not to have moister sensors on all the zones.

U won't find any moisture sensors that far north in stock. Sell them on the benefits of having an ET based system.

I do like the Weather Matic SL w/weather station, but if you've got three
clocks...$$$$$ also.

3 clocks because 3 major buildings.... I haven't figured out why the original contractor didn't install one clock and design for phasing the installation. Would certainly simplify matters substantially.

One of the things that challenges us "northerners" is how our length of day varies. By mid-summer, we don't have sunset until 10:30 pm. Southern and western exposures need wildly varying water amounts depending on the month. I've pretty much given up training customers to bump up the water by 50% on those areas for July/August. North and East exposures don't have nearly the variation in water requirements because it is normally so damned chilly in the morning. I would love to see ET clocks become common here.... would solve a great deal of headaches...

Multiple clocks are a pain, especially if commons interact, then relays,
electricians come into view. We manage all our systems, so you mite shoot
a proposal to your clients about a management contract...check operation
every month..fire the zones, walk thru, clean nozzles, poke with meter,
adjust percentages, winterize. It's the bread & butter of the biz.
A remote hook up for each clock is no joke at all. We winterized the county
courthouse north of here the other day..had a TRC remote that would not blow
thru the building to the perm. RB card installed, had to stand in two places &
use walkies to communicate..worthless!

This company here makes one i'm experimenting with. Sent the thread on my experiment to the top of the thread list.

Comes with a monthly fee.payup Other than that GM what has been your experience?

IMHO the best "smart" controller will combine both ET and soil moisture sensing and support flow sensing. That being said, Calsense in the only controller I know of that supports all of these with almost unlimited flexibility in hydrozone design.

With respect to field sensors tied into valve groups, there are several manufacturers that have sensors that do this, however once you go above 1-2 sensors it starts to run up in the $$$ column, at which point you start to wonder if it would not be better to get an all-in-one solution.

So I guess the place to start is with allowance -> how much scratch to you have to play with?
