Oilfield Water Injection Metering: LGF-PA66 Selection Guide

An oilfield injection system splits into a low-pressure distribution side and a high-pressure wellhead side - the metering logic differs completely.

For low-pressure lines inside injection stations and wellhead manifolds (typically <= PN16/25), the LGF-PA66 aviation-grade electromagnetic flow meter works well: PN16 rating covers distribution networks, and +/-0.2% accuracy satisfies per-well injection allocation KPIs. The PTFE liner resists chlorides, sulfates and other aggressive ions in injection water; choose 316L, Hastelloy or titanium electrodes based on water chemistry. For polymer-flooded injection water, verify conductivity first - polymer solutions tend to be less conductive, but anything >= 5 uS/cm meters stably; below that, contact our technical team for an assessment.

High-pressure wellheads (above 16 MPa) require dedicated high-pressure electromagnetic meters or other technologies - the LGF-PA66 must not be installed directly at the wellhead. This is a hard boundary.

Most injection well sites are remote without grid power, so pair the LGF-PA66 with an EC32 or EC60 low-power RTU: Modbus RS485 data acquisition, 4G/NB-IoT backhaul to the oilfield IIoT platform, solar panel plus battery supply, and IP68 protection for outdoor well sites. Once per-well injection data uploads automatically, allocation adjustments and loss analysis no longer need manual meter reading.
