Control valve to be housed with the flow meter in a common rectangular valve <br />box with locking lid marked "F.M." "M.C.V.". <br />K. MOISTURE SENSORS <br />1. Installation of moisture sensors shall be the responsibility of the Contractor. All <br />sensor locations should be marked on record plans as well as in the field. At each <br />sensor, provide a 1-1/2 inch x 12-inch PVC pipe with a cap within 2 inches of <br />sensor, set flush with finish grade, for future location of unit. Correct sensor <br />placement and installation shall be verified before project is signed off. The <br />Engineer shall call material supplier before project is signed off to verify the <br />proper installation and operation of all moisture sensors <br />2. Location decision of the moisture sensors is provided by the material supplier. <br />The Contractor shall contact material supplier in determining sensor placement. <br />However, the Contractor must have the controller installed with field station wires <br />hooked up according to plan. There must be electricity to the controller, as well <br />as lateral lines installed and irrigating respected areas. The Contractor shall <br />contact material supplier 5 working days in advance when scheduling an <br />appointment for sensor flagging. <br />3. Material supplier field representative shall provide on-site evaluation of the <br />project area. Groups of similar areas are determined and flagged with the <br />Contractor as to where a moisture sensor should be installed. A demonstration on <br />how to install a moisture sensor is also given. By physically viewing coverage, <br />types of heads, soil types, exposure, and varying plant material, proper sensor <br />placement is assured. <br />4. Wiring: <br />a. Wires shall be direct burial from the remote control valve to the moisture <br />sensor. They shall consist of one (1) yellow-coated and one (1) white-coated and <br />color-striped same color as pilot wire U.F. type, U.L. approved, AWG number 14 <br />solid strand copper wire with minimum 4/64" PVC coating, 600 volt, 75oC. <br />b. Connections shall be water tight epoxy cast Scotch Pak-3470 or equal. <br />505 E Central Ave <br />#B11/6/2024
