Emerson PN 51-FCL-1056 Specifications General, Specifications Sensor, Specifications Analyzer

MODEL FCL-1056

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 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. 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.

SECTION 1.0
