Pressure Gauges
Pressure Monitoring, an important function.
Pressure gauges are used to monitor the pressure at various points of the system.
The best quality for pressure gauges is "liquid filled", however standard gauges work good enough for irrigation use. If you do use a standard gauge, don't leave it connected to the water pipe. The constant pressure will destroy it.
Pressure testing
laterals - Randomly check lateral inlet and outlet pressures
and compare the results with the initial baseline
tests.
For most systems, it is recommended that the pressure variation not exceed 20% of the design pressure. When differences are noted, clogging may be occurring and
corrective actions need to be taken.

Operating pressures of microirrigation or low volume systems can be measured using a portable pressure gauge equipped with a fitting, which allows easy measurement. |
