Stevens Water Monitoring Systems

What Stevens Water Monitoring Systems does

Stevens Water Monitoring Systems, founded in 1911 in Portland, Oregon, is the most senior company in the hydrological and environmental monitoring industry, having invented the original water level chart recorder. The company designs and manufactures a vertically integrated environmental data acquisition ecosystem that combines proprietary hardware sensors (notably the patented HydraProbe coaxial impedance soil sensor, Smart PT pressure transducers, Van Essen Diver groundwater loggers, and Met One precipitation gauges), IoT data loggers (the Steelhead platform and eTracker telemetry), and the SkyView360 cloud-based data management platform, organized around its "Measurements to Mind" (M2M) strategy.

The customer base spans five primary segments: government water agencies (USDA SNOTEL/SCAN, NOAA Climate Reference Network, Jamaica WRA, Florida DEP, California ARB, Riverside County Flood Control), agriculture and irrigation operations, environmental research institutions (CERN, Oregon State University), sports turf and golf management, and industrial/utility infrastructure monitoring via the Viper transformer solution. Selected customers include a 2,000-acre jalapeno operation in Imperial Valley and a 50+ year flagship deployment with Jamaica's Water Resources Authority spanning 31 rainfall sensors, 130 stream gauging stations, and 275 monitoring wells.

Revenue is generated through one-time hardware sales of sensors and data loggers, likely subscription or SaaS fees for the SkyView360 cloud platform, and professional services for system integration and custom deployment. Go-to-market combines a global distributor and reseller network for mid-market reach with direct enterprise sales for government and large agricultural accounts, supplemented by industry conferences, technical webinars, and content marketing. The company operates as a privately held Oregon corporation with three wholly owned subsidiaries (SoilMoisture Equipment Corp, POGO Turfpro, Dyacon) and no disclosed venture or private equity investment.

Direct peers

• Campbell Scientific: Campbell Scientific is the most direct competitor — a long-established manufacturer of rugged data loggers, environmental sensors, and telemetry systems sold to government, research, and agriculture customers with very similar deployment profiles (e.g., USDA, NOAA, university research). Closely aligned with Stevens' Measurement-to-Mind stack.
• METER Group (formerly Decagon Devices): METER Group builds soil moisture, water potential, and weather sensors (e.g., TEROS, AquaLab) used widely in agriculture and environmental research. Direct overlap with Stevens' HydraProbe, GroPoint, and TS15 product lines.
• Sentek Technologies: Sentek specializes in soil moisture profiling sensors and irrigation decision tools — directly overlapping with Stevens' GroPoint Profiling and SAGE irrigation products, particularly in precision agriculture.
• Onset Computer (HOBO Data Loggers): Onset's HOBO data loggers and weather stations are widely used in environmental and agricultural monitoring, overlapping with Stevens' eTracker/Steelhead data acquisition category, though more oriented to mid-market/research users.
• Irrometer: Irrometer manufactures tensiometers and soil moisture sensors targeted at agriculture and irrigation — directly comparable to Stevens' TS-series tensiometers and SAGE visual tensiometer.
• Pessl Instruments (METOS brand): Pessl/METOS is a global player in agricultural weather stations, soil moisture sensors, and disease-modeling IoT — directly comparable to Stevens' agricultural irrigation and weather station portfolio, with stronger SaaS/decision-support software orientation.
• AquaCheck: AquaCheck manufactures soil moisture probes for irrigation scheduling in agriculture, golf, and research — overlapping with Stevens' GroPoint, HydraProbe, and POGO turf product lines, particularly in international markets.

Broad incumbents

• Vaisala: Vaisala is a global incumbent in meteorological and environmental measurements (weather stations, lightning, road weather). It overlaps with Stevens' Dyacon and Met One precipitation products but operates at a much larger scale across a broader portfolio.
• Xylem (YSI, Hach, SonTek): Xylem's water brands (YSI multi-parameter sondes, Hach water quality) compete with Stevens' Eureka Trimeter/Manta sondes and water quality segment. Much larger global water-utility footprint and broader portfolio.

Emerging players

• Davis Instruments: Davis Instruments provides consumer/prosumer weather stations and environmental sensors. Less rugged than Stevens/Dyacon but competes for hobbyist, agricultural, and small-scale professional monitoring use cases.
