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 pressure
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" OD tubing compression fitting
(barbed for use with soft tubing)
Drain connection: 3/4" barbed fitting. Sample must drain to open atmosphere.
Wetted parts: Overflow sampler and flow cell: acrylic, polycarbonate, Kynar,
nylon, silicone
Chlorine sensor: Noryl, Viton, wood, silicone, polyethersulfone, polyester
and platinum
pH sensor: Tefzel®4, Viton, glass, ceramic
Response time to step change in chlorine: <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)
SENSOR
Free chlorine range: 0 to 10 ppm as Cl2. 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. 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.
Electrolyte volume: 25 mL (approx.)
Electrolyte life: 3 months (approx.); for best results replace electrolyte monthly.
