Hydrological Sensor
Focused Photonics Inc. (FPI) enhances water resource management with its Hydrological Sensors, providing accurate, non-contact measurements of level, flow, velocity, and rainfall in rivers, reservoirs, and flood-prone areas. The radar and Doppler series utilize microwave and ultrasonic technologies for reliable data in harsh conditions, complying with ISO 1438 and USGS standards.
Hydrological Detection Principles
Nutrient and disinfectant analyzers quantify biological and chemical indicators through fluorescence, absorbance, and selective reactions. FPI’s sensors use 470 nm excitation for chlorophyll-a (0-50 μg/L, ±0.01 μg/L) and blue-green algae, UV absorbance at 254 nm for COD (0-1000 mg/L, ±0.1 mg/L), ISE for ions (0-10 mg/L, ±0.05 mg/L), and DPD chemical method for residual chlorine (0-5 mg/L, ±0.02 mg/L), per ISO 7027.

Evolved from 1990s fluorometers, these analyzers integrate pretreatment for particulates and AI for peak deconvolution. FPI refines with drift-free LEDs and auto-calibration (5-40°C), ensuring <1% uncertainty per GB 3838-2002. In 2025’s eutrophication surge, our portables fuse satellite chlorophyll data for predictive mapping, informing EU WFD nutrient thresholds and SDG 6 water purity.
