Series 3100
Orifice Plate Landfill Gas Wellhead

Orifice Plate Landfill Gas Wellhead


Historically, consistent and repeatable data acquisition is problematic during well field monitoring. One REP solution for this problem is the Orifice Plate Landfill Gas Wellhead, Series 3100.


The Orifice Plate Landfill Gas Wellhead includes a multi-turn gate valve for smooth flow adjustment. The Series 3100 employs a union style orifice plate in either HDPE or PVC depending on specification/operator preference. A range of orifice plates are provided with each wellhead to ensure your differential pressures stay within the recommended ranges for flow calculation. Available long sweep design provides lowest overall pressure drop, which benefits LFGTE operators.
