DIRECTIONS

Use the Turf Tec Infiltrometer to determine the amount of water that the soil will

absorb in an hour.

This is determined by inserting the cutting rings of the Infiltrometer into the turf at

the center of the radius of the sprinkler throw. Fill both rings with water and start

the timer for 15 minutes. When the timer rings, stop it, read the number of inches

on the scale and multiply this number by four. This will give you the hourly rate

that it takes for water to move down into the soil.

EXAMPLE: If the Infiltrometer scale indicates that water is being absorbed by the

soil at the rate of 1/2 inch in 15 minutes. Multiplying this by four will total 2 inches

per hour. The clocks on the irrigation system should then be adjusted to deliver

only as much water the soil can absorb, or set the timer to irrigate every 20

minutes or half hour, etc.

HOW TO USE TURF-TEC PRECIPITATION

GAUGES:

Placing precipitation / uniformity gauges to check single row system:

The precipitation / uniformity gauges come with 16 large gauges and 4 smaller

gauges. The smaller gauges should be used at both ends to allow the area just

next to the sprinkler head to be measured.

1. Insert stainless steel spikes into the ground to a depth of about three

inches deep in the area to be tested.

2. Be sure smaller gauges are placed closest to the sprinkler heads to catch

the second or third nozzle that is designed to water directly around the

sprinkler head.

3. Hang the plastic collection gauge on the flat part of the stainless steel

stand so that the bottom of the gauge is still about one inch above the soil

surface.

Gauge Placement

Single row method:

Place the one small Precipitation Gauge two feet from sprinkler head. The

second small gauge can be placed anywhere from two to four feet from the first

Gauge. The number of Gauges needed will be determined by the spacing and

the number of feet that the sprinkler head will throw. All Gauges should be in a

straight line in the radius from the head to its outer perimeter with the small

gauges at either end. The closer the Gauge placement, the more accurate the

results will be.
