Standard pressure gauges do not work well for effluent, they block. The TechniPharm specially developed effluent gauge does not block and is particularly suitable for monitoring effluent system pressures at any point from pump to irrigator. FDE rules stipulate a pressure gauge should be mounted at the pump end and at the last hydrant end to the Irrigator.
FDE Guideline on Pressure Variation:
The FDE land application system must be designed to apply within +/- 10% of target applied depth with acceptable uniformity and application intensity in any location. In general the total pressure at the applicator(s) should not vary by more than:
20% of the design operating pressure at any point in the system
Provision must be made for pressure measurement at the outlets/sprinklers as well as at the pump.
