1.3 SPECIFICATIONS — GENERAL
Sample requirements:
Pressure: 3 to 65 psig (122 to 549 kPa abs)
A check valve in the inlet prevents the sensor
flow cells from going dry if sample flow is lost.
The check valve opens at 3 psig (122 kPa abs).
If the check valve is removed, minimum pres-
sure is 1 psig (108 kpa abs).
Temperature: 32 to 122°F (0 to 50°)
Minimum Flow: 3 gal/hr (11 L/hr)
Maximum flow: 80 gal/hr (303 L/hr); high flow
causes the overflow tube to back up
Sample Conductivity: >50 µS/cm at 25°C
Process connection: 1/4-in OD tubing compression
fitting (can be removed and replaced with barbed
fitting for soft tubing)
Drain connection: 3/4-in barbed fitting. Sample must
drain to open atmosphere
Wetted parts:
Overflow sampler and flow cell: acrylic, polycar-
bonate, Kynar
®1
, nylon, silicone
Chlorine sensor: Noryl
®2
, Viton
®3
, wood, silicone,
polyethersulfone, polyester, and platinum
pH sensor (3900VP) : Stainless steel, glass,
Teflon
®4
, polyphenylene sulfide, EPDM, and
silicone
Response time to step change in chlorine concen-
tration: <80 sec to 95% of final reading for inlet
sample flow of 3 gph (11 L/hr)
Weight/shipping weight:
Model FCL-01: 10 lb/13 lb (4.5 kg/6.0 kg)
Model FCL-02: 11 lb/14 lb (5.0 kg/6.5 kg)
[rounded to the nearest 1 lb. (0.5 kg)]
1.4 SPECIFICATIONS — SENSOR
Free chlorine range: 0 to 10 ppm as Cl
2
. For higher
ranges, consult the factory.
pH correction range: 6.0 to 9.5. For samples having
pH between 9.5 and 10.0, consult the factory. If
pH < 6.0, correction is not necessary. For manual
pH correction, choose option -01. For continuous
pH correction choose option -02.
Accuracy: Accuracy depends on the accuracy of the
chemical test used to calibrate the sensor.
Interferences: Monochloramine, permangante,
peroxides.
Electrolyte volume: 25 mL (approx.)
Electrolyte life: 3 months (approx.); for best results
replace electrolyte monthly.
1.5 SPECIFICATIONS — ANALYZER
