General Information
Glossary
Refer to Figure I-3.
Inlet Valve – Accepts the sample stream via 1/4 inch NPTF connector.
The user must supply the sample with a pressure between 14 and 100 psig.
Inlet Filter – 60-micron stainless steel filter traps particulate matter in
sample stream.
Bypass/Needle Valve – Used to redirect flow in bypass system.
Pressure Regulator – Adjusts flow on incoming sample stream.
Flow Meter – Measures sample flow rate.
Check Valve – Prevents the backflow of sample.
Restrictor Tube Assembly – Used in conjunction with pressure regulator
to lower downstream pressure.
Reagent Manifold – Directs sample flow in and out of reagent bottle
assembly.
Reagent Bottle Adapter Assembly – Connects reagent bottle assembly to
manifold.
Diffusion Tubing Assembly – Semi-permeable tubing through which
reagent diffuses into the sample.
Reagent Bottle – Contains formic acid reagent that lowers the sample pH
to below 4.
Flow Cell – Contains reference electrode, sensing electrode and ATC probe.
Diverter Valve – Allows the flow cell reservoir to fill during calibration by
forming a closed-loop system.
Ammonia Electrode – Senses ammonia ions in sample stream and produce
an electrical potential dependent on sample concentration.
Reference Electrode – Provides a constant reference potential and
completes the measurement circuit.
Reference Electrode Filling Solution Bottle – Provides constant flow of
electrolyte solution through reference electrode for maximum stability.
