Overview
The Global Water FSS Flow Sampling System is a field-deployable, integrated solution engineered for accurate, reliable, and compliant monitoring and proportional sampling of open-channel wastewater, stormwater, and industrial effluent flows. Based on hydrostatic depth measurement and empirically validated stage–discharge relationships, the system combines a robust flow monitor (FC220), a programmable composite sampler, and a multi-parameter data logger into a single portable platform. It operates without external power sources for extended deployments—enabled by an onboard rechargeable battery—and is designed to meet the operational demands of environmental compliance programs, municipal wastewater reporting, and industrial pretreatment monitoring under regulatory frameworks including EPA Method 1664, ISO 5557, and ASTM D5905.
Key Features
- Integrated tri-module architecture: FC220 open-channel flow monitor, proportional composite sampler, and high-integrity data logger—all co-located and synchronized
- FC220 flow monitor with high-stability piezoresistive pressure transducer (±0.25% FS accuracy) for continuous water depth measurement
- Pre-loaded calibration tables for over 20 standardized flumes and weirs (e.g., Palmer-Bowlus, Parshall, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus) — fully editable via on-device 4-button interface
- Proportional sampling triggered by real-time flow rate or cumulative volume; adjustable sample volume (100–2,000 mL per event) and sampling interval (1 min to 24 h)
- Chemically inert peristaltic pump with FDA-compliant tubing; eliminates cross-contamination between samples and supports long-term unattended operation
- Ruggedized, IP67-rated transport case with lockable lid, integrated battery compartment, and modular mounting for field installation
- Onboard lithium-ion battery providing up to 30 days of continuous operation (typical configuration); includes smart charger with status LED and AC/DC input options
Sample Compatibility & Compliance
The FSS system accommodates standard 1–2 L polyethylene sample bottles (ISO 5667-3 compliant), with optional borosilicate glass bottles for volatile organic analysis (EPA Method 502.2, 524.2). All wetted materials—including pump tubing, inlet lines, and bottle caps—are certified non-leaching and compatible with pH 2–12 aqueous matrices. The FC220 sensor meets EN 12957 for open-channel flow instrumentation and supports audit-ready data logging aligned with GLP and GMP principles. Flow algorithms conform to ISO 4359 (weir and flume discharge equations) and USGS Techniques of Water-Resources Investigations Book 3, Chapter A12. Data integrity is preserved through timestamped records with embedded sensor diagnostics and battery voltage tracking.
Software & Data Management
The included Windows-compatible desktop software enables full configuration of sampling protocols, calibration coefficient entry, and firmware updates via USB. Logged data exports directly to CSV format—fully compatible with Microsoft Excel, MATLAB, and statistical analysis platforms—without proprietary conversion utilities. Each record contains UTC timestamp, instantaneous depth, calculated flow rate (L/s or m³/h), cumulative total flow (m³), pump actuation events, and system health flags. Audit trails include user-initiated parameter changes with date/time stamps, satisfying 21 CFR Part 11 requirements when used in regulated environments. Optional cloud synchronization (via third-party gateway) supports remote data retrieval and alarm notifications.
Applications
- Municipal wastewater treatment plant influent/effluent flow verification and composite sampling for BOD/COD/NH₃-N analysis
- Industrial pretreatment program compliance monitoring at discharge points subject to NPDES permits
- Stormwater outfall characterization during wet-weather events per EPA SWMM guidelines
- Baseline flow profiling for watershed-scale hydraulic modeling and sewer capacity assessment
- Field validation of ultrasonic or magnetic flowmeter installations in gravity-fed conveyance systems
- Research-grade longitudinal sampling for nutrient loading studies in agricultural runoff channels
FAQ
Can the FC220 monitor be calibrated in the field without specialized equipment?
Yes—the FC220 supports zero and span adjustments using its built-in menu system and a reference depth gauge; no external calibrator is required for routine verification.
Is the system suitable for freezing-temperature environments?
The FC220 housing and electronics are rated for −20 °C to +60 °C operation; optional heated sensor housings and insulated sample bottle carriers are available for sustained sub-zero deployments.
Does the data logger support external sensor inputs beyond flow?
The base unit logs only flow-derived parameters; however, the optional FSS-EXT expansion module adds four analog (4–20 mA / 0–5 V) and two digital (pulse/tally) input channels for concurrent turbidity, pH, or temperature integration.
How is traceability maintained across sampling events?
Each sample bottle is assigned a unique sequential ID tied to its acquisition time, flow rate at trigger, and cumulative volume—recorded both in the logger memory and printed on optional thermal label tape.
What maintenance intervals are recommended for long-term deployment?
Pump tubing should be replaced every 6 months under continuous use; pressure sensor diaphragm inspection and cleaning are advised annually or after exposure to abrasive sediments.
