water audits with smartlines

Discussion in 'Irrigation' started by londonrain, Mar 16, 2008.

  1. I have been performing water audits and setting up smartline controller with weather monitors.

    For you contractors that are installing smartline's do you use the defaults IE: rotors, sprays, drip etc or do you calculate precipitation rates. I have been calculation precipitation rates..
    These are the rates I have calculated on one system I adopted.
    zone #1 rotor zone .385" in/hr
    zone #2 rotor zone .480" in/hr
    zone #3 rotor zone .65" in/hr
    zone #4 spray zone 1.03" in/hr
    zone #5 rotor zone .165" in/hr
    zone #6 rotor zone .25" in/hr
    zone #7 rotor zone .24" in/hr
    zone #8 spray zone 1.65" in/hr
    zone #9 rotor zone .34" in/hr
    zone #10 rotor zone .32" in/hr
    zone #11 rotor zone .5" in/hr
    As you can see if you don't calculate the PR rate and you just slap up a smartline , then you are not programing the controller correctly...

  3. I calculate precip rates as well. If the spacing is proper I'll use the manufacturers precip rates. I don't do collection tests but have considered it.

    Anyone care to share different methods of determining precip rates in the field on installed systems? Perhaps another thread?
     
  5. I use the total area method of calculating the precipitation rates...

    There is no real way to determine ACTUAL precipitation rates. as soil
    conditions, windage, etc., come into play. Best for me have been moisture
    probes. The catalogs can give rates, but you are site specific, every time.

    Well, yes that is a given. I was speaking with regard to programming the WMSL. BTW, where have you been lately. :waving:
