Stevens Water Monitoring Systems, Inc. products
Stevens - Measurements To Mind - Unique Data Processing and Network Connectivity
Unique data processing and network connectivity for true direct cloud connectivity. Getting environmental data to the point of actionable information has historically compartmentalized the data flow path into separate components—sensors, datalogger, telemetry, power management, software.
Van Essen - Water Level - Pressure transducers with integrated data logger
The Diver product suite provides advanced and dependable groundwater monitoring solutions, featuring an integrated data logger and power source capable of measuring fluid levels, temperature, and electric conductivity. Developed for applications in urban water management and water resource management, Diver data loggers facilitate comprehensive data collection, making them suitable for long-term water level monitoring projects such as aquifer storage and recovery. Built to endure challenging environmental conditions, the Diver products are also appropriate for coastal zone aquifer management.
Apogee - Accurate and Stable Global Shortwave Radiation Measurement
Apogee Instruments’ silicon-cell pyranometers feature a silicon-cell detector. The sensors are accurate, stable, durable, and cost-effective, the results of continual refinement of design.Water Level Sensors - Pressure
Stevens - Level Pressure, Temperature and Digital Crest Gauge Sensor
Stevens’ Smart PT is a ceramic membrane pressure and temperature sensor that provides highly accurate measurements (0.05% of full scale) across a broad range of fluid level monitoring applications. In addition to real-time instantaneous readings, this intelligent sensor offers capabilities such as capturing peak crest levels and automatically sampling and reporting basic statistical data at configurable time intervals. The device features programmable corrections for local variations in Earth's gravitational field and automatically compensates for changes in water temperature and density. Encased in a corrosion-resistant stainless-steel housing with potted electronics, the Smart PT is designed to be durable and reliable for submersible water applications.
Stevens - Pressure Transducer
The Stevens SDX (Submersible Depth Transmitter) is a pressure sensor that provides accurate measurement results while offering an affordable solution suitable for various level measurement applications. Its high-impact, corrosion-resistant PVC Type II housing and potted electronics ensure durability in most water and challenging fluid environments. The copper tip is designed to reduce algae growth. The SDX is also an ideal option for level measurement applications where more expensive sensors may be at greater risk of damage. The device includes specified vented cable lengths, with the vent serving as an atmospheric reference for the sensor, which is essential for maintaining optimal measurement accuracy. The PVC housing features integrated pipe threads for secure installation into pipes, tanks, or other relevant applications.Water level Sensors - Non-Contact
Stevens - Non-Contact Water Level Sensor
The IRU-2420 provides a non-contact method of detecting level, presence/absence detection, volume, proximity and distance. With built in technology to compensate for unpredictable variables such as humidity, temperature and agitators, the IRU is the right sensor for your application.
Stevens - Two Non-Contact Water Level Radar Sensor
Two non-contact water level radar sensors for outdoor use using impulse 24 GHz or 80 GHz plus and continuous wave radar technology. Conventional pulse radar emits periodic high-frequency pulse and continuous wave radar emits a continuous wave signal. The continuous wave radar can be a single-frequency continuous wave or a frequency-modulated continuous wave. 24 GHz radar sensors are typically used for applications where the measured surface is highly reflective, such as liquids and powders. 80GHz radar sensors are typically used for applications where the material being measured is less reflective, such as granular or bulk materials. 80GHz radar sensors have a smaller wavelength and can detect a higher resolution level and can also penetrate through dust, steam, or foam.
Water Level Sensors - Shaft Encoders
Stevens - Position Analog Transmitter
The Position Analog Transmitter (PAT) is a stand-alone water level shaft encoder. The PAT is ideal for industrial and hydropower applications with a 4-20 mA output. A precision potentiometer is the measuring element, and a number of ranges are available, depending on gear selection.
Water Flow, Velocity, and Discharge Measurements
Stevens - Surface Velocity Radar (SVR) Sensor
SVR is a non-contact method for measuring surface flow velocity in open channels. The SVR uses radar technology to measure the Doppler shift of electromagnetic waves reflected from the water surface. The Doppler shift is proportional to the water’s surface velocity and can calculate the velocity of water at various depths.
