Overview
The GS-WCL500 is an integrated multi-parameter water quality panel that combines chlorine (amperometric or DPD, selectable), pH, turbidity, and temperature on a single 7″ touchscreen controller — reducing cabinet footprint, wiring, and commissioning effort for drinking-water, wastewater, and food-grade process installations.
- Selectable amperometric or DPD chlorine method
- Integrated pH, turbidity, and temperature sensors
- 7″ color touchscreen with data logging
- Modbus TCP/IP over Ethernet for SCADA integration
- 4 configurable SPDT alarm relays (high/low)
- IP65 / NEMA 4X wall-mount enclosure

Evidence Notes
Integrated water-quality panel architecture
The v1 applications place this panel in municipal drinking water, wastewater, food and beverage CIP, and cooling-tower control. The architecture combines selectable chlorine measurement with pH, turbidity, temperature, SCADA outputs, and alarm relays for aqueous water-quality control.
Technical & Engineering Details
Secondary engineering detail — expand each topic for the full measurement, envelope, sample-system, calibration, and maintenance information.
01 Measurement Principle
How the measurement is bounded
Multi-parameter water-quality panel combines selectable amperometric or DPD chlorine measurement with pH, turbidity, and temperature channels.
Requires
- Method selection between amperometric and DPD chlorine measurement
- pH, turbidity, and temperature sensors configured for the water application
- SCADA mapping for the four analog outputs, RS485, Modbus TCP/IP, and alarm relays
Interferents and Limits
- Turbidity and color can affect DPD photometric workflows
- pH shifts can change free-chlorine speciation
- Fouling on amperometric sensors changes response if maintenance is not matched to water quality
- Single-parameter chlorine duty may not need a multi-parameter panel
- Water temperature, pressure, flow, and pH numeric ranges are not stated in v1 source data
- Chlorine-air area monitoring is outside this aqueous panel boundary
02 Operating Envelope
Use these limits as selection inputs, then confirm sample condition, ambient exposure, and materials before quotation.
- Use without method selection between amperometric and DPD chlorine measurement
- Use without SCADA and alarm mapping review for multi-channel outputs
- Use as a chlorine-air area monitor
03 Sample System Boundary
Sampling mode, conditioning components, and exclusions define where the analyzer responsibility ends and the sample system begins.
- wall-mount controller panel
- selectable chlorine channel
- pH sensor
- turbidity sensor
- temperature sensor
- sample bypass or online flow path
- Not a stack, duct, or ambient-air chlorine detector
04 Calibration & Validation site-specific
Calibration method, interval, and traceability are shown only when structured data is available.
Zero / Span Method
Calibration workflow depends on selected amperometric or DPD chlorine method plus pH, turbidity, and temperature channels
Interval
Not stated in v1 source data
05 Maintenance & Spares site-specific
Tasks, consumables, and access items are shown only when structured maintenance data is available.
- Maintain the selected chlorine method path, either amperometric or DPD
- Verify pH, turbidity, and temperature channels during scheduled water-quality checks
- Confirm alarm relay and SCADA mapping after commissioning or method changes
- Review sensor fouling risk for wastewater, food-grade CIP, and cooling-water duty
- Selected chlorine-method consumables
- pH sensor service parts
- turbidity cell service parts
- calibration standards
