ST112A Dual-Element Mass Flow Meter
Brand: Fluid Components International LLC (FCI)/ST112A-Dual-Element-Mass-Flow-Meter/002_FCI_ST112_Dual-Element_Mass_Flow_Meter.png)
The FCI Model ST112 is a dual-element system that can be applied in an averaging mode or as two discrete and independent sensors operating through a single transmitter.
A single dual-element instrument can result in significant cost and space savings compared to installing and integrating two single-element instruments.
Model ST112 features FCI’s exclusive patented VeriCal system. VeriCal provides you with the ability to perform periodic field validation and verification of the flow meter’s measuring performance and calibration without extracting the flow meter from the pipe or process.
