.
Inlet Valve –
Accepts the sample stream via 1/4 inch NPTF connector. The
operator must supply the sample with a pressure between 14 and 100 psig.
Inlet Filter –
60 micron stainless steel filter traps particulate matter in the
sample stream.
Bypass/Needle Valve –
Used to redirect flow in the bypass system.
Pressure Regulator –
Adjusts flow on the incoming sample stream.
Flow Meter –
Measures the sample flow rate.
Check Valve –
Prevents the backflow of sample.
Restrictor Tube Assembly –
Used in conjunction with the pressure
regulator to lower downstream pressure.
Flow Cell Manifold –
Directs sample flow in and out of the flow cell.
Flow Cell –
Contains the chloride sensing electrode, reference electrode and
ATC probe.
Diverter Valve –
Allows the flow cell reservoir to fill during calibration by
forming a closed-loop system.
Chloride Electrode –
Senses chloride ions in the sample stream and
produce an electrical potential dependent on sample concentration.
Reference Electrode –
Provides a constant reference potential and
completes the measurement circuit.
Pressurized Reference Electrode Filling Solution Bottle –
Provides
constant flow of electrolyte solution through reference electrode for
maximum stability.
ATC Probe –
Measures the sample temperature and inputs data to
microprocessor for automatic temperature compensation (ATC).
Calibration Port –
Allows introduction of standards to the sample reservoir
during calibration.
Air Pump –
Used to mix the sample during both measurement and
calibration as well as provide air to pressurize the reference electrode filling
solution bottle.
