PFSPrimary Flow Signal (PFS), designer and manufacturer of flow-metering solutions for oil & gas, water/wastewater and industrial applications, announces its solutions for highly accurate open channel and sewage flow measurement in municipal water/wastewater facilities. Metering discharge levels, or liquids as they are released from a free falling environment, is a calculated and important process which is commonly encountered in water/wastewater applications. The PFS-HN nozzle is designed for open channel flows and provides accuracy even in excessive pipe slope conditions. Configuration of the PFS-HN also allows the nozzle to manage high velocity flows — handling open channel, sewage or sludge flows to provide a dependable and highly accurate solution for water and flow management needs.
