Description
The Yokogawa FC800D is a non-reagent sensor unit for continuous free available chlorine measurement with the FLXA402T. It uses an amperometric polarographic method and a rotating electrode with cleaning beads to maintain the measuring surface.
Verified technical overview
| Measured object | Free chlorine in tap-water applications |
|---|---|
| Measurement method | Amperometric polarographic method using a rotating electrode |
| Published ranges | 0–1 to 0–3 mg/L for -F1/-C1; 0–5 mg/L for -F2; 0–10 mg/L for -F3 |
| Sample temperature | 0 to 50 °C; temperature compensation is effective within 0 to 40 °C |
| Sample limits for -F1/-C1 | 0.1–2.5 L/min and 1–150 kPa; pH and conductivity limits are configuration-dependent |
Engineering selection checklist
Provide normal and maximum chlorine concentration, pH and conductivity variation, sample temperature, flow, pressure and suspended-solids information. The -F1, -C1, -F2 and -F3 variants have different application limits; do not select on range alone.
| Process data | Measurement objective, normal/minimum/maximum value, medium chemistry, temperature and pressure |
|---|---|
| Installation | Sample or immersion arrangement, connection, cable distance, cleaning and maintenance access |
| System interface | Compatible analyzer or host, power, output, communication and alarm requirements |
| Documentation | Confirm the current Yokogawa general specification and complete order code before purchase |
Industry application guidance
The FC800D is intended for free-chlorine control and monitoring in drinking-water distribution and treatment processes. Where combined chlorine or variable sample chemistry is material, compare the reagent-type RC800D and confirm the measurement objective with the current Yokogawa selection data.
