Irrigation water measuring devices.

Devices and techniques for measuring flow accuracy. The amount of water available to the plants from the soil determines when and how much irrigation water to apply. This publication provides the following information you will need for measuring soil water. Water is a precious commodity and water shortages continue to be a topic of discussion year after year.

The final selection of the type of water flow measurement device will depend on the volume of water to be measured the degree of accuracy desired the desired permanence of installation and the grade or fall of the ditch or stream. Devices used for measuring irrigation water several devices are commonly used for measuring irrigation water. Most irrigation meters should have an accuracy of 2 0 of the actual amount. Irrigation water management begins with knowing how much water is available for irrigation.

Thus the first step in irrigation scheduling is to measure the moisture content of the soil. Wide range of capacity. The types of soil water measuring devices available. The measured flow should be as close as possible to the actual amount of water flowing in the pipe.

But what most people don t realize is that a large portion of their water usage comes from landscape irrigation. Can be made from wood metal or concrete but they must be fabricated to precise dimensions and properly installed to measure irrigation water accurately. Digiten water flow control meter lcd display controller g1 2 water hall sensor flow meter flowmeter counter 1 30l min g1 2 solenoid valve normally closed n c dc 12v power adapter by digiten 49 99 49. Measurement accuracy is the difference between the true flow and the flow measured with a meter.

A flume with a 1 foot throat will measure from 1 3 cfs to 10 cfs. The material provided in this section is intended to serve as a framework for irrigation water measurement training. This weir is patterned after an old proven system used by the salt river project and the roosevelt water conservation district of arizona for over 50 years. 99 64 99 64.

A precision water measuring device for all standard concrete ditches. In many cases overwatering is the cause of problems in plants and turf. Water irrigation is necessary for agriculture turf gardening etc and water resource is becoming more expensive. Thus it is necessary to install flow measurement device to know how much water rate you have used.

The portable weir will help in figuring pump efficiency crop usage and percent of efficiency of water in leveling.
