The Basics of Evapotranspiration
Evapotranspiration (ET) represents the loss of water from the Earth’s surface from the combination of direct evaporation and plant transpiration. ET is usually expressed as a rate such as inches per day. Knowledge of ET is important for irrigation scheduling but it is also an important factor for other land use applications such as septic …
Meteorology Sensors Overview
Weather conditions are often an integral element in water resource and irrigation management applications. Weather parameters are frequently used in understanding and modeling environmental applications that are dependent on water resources. Stevens provides top quality and industry leading weather sensors that are easily deployed into an integrated environmental monitoring and control system. Here is an …
Soil Sensors Overview
As a leader in soil monitoring instrumentation, Stevens offers portable and in-situ sensors to measure moisture, EC (salinity), temperature and matric potential. Moisture, EC and Temperature – In-Situ Used in more water supply forecast and climatological networks than any other soil sensor. The most scientifically researched soil sensor available. RELIABLE: Continual, long-term data without calibration. …
Staff Gages Overview
Stevens’ environmentally rugged staff gages provide a quick and easy visual indicator of water level and flow. Every water level monitoring station should include a staff gage from which the height of the water may be visually and easily compared to any data logger’s reported measurement. Enamelled iron gages are preferred over other type gages …
Water Level Sensors Overview
Stevens is the original water level measurement instrumentation company with the introduction of the widely known chart recorders introduced in 1911. Today, Stevens offers a wide selection of water level measurement sensors including robust ceramic pressure sensors, shaft encoders, acoustical sensors, and visual reference staff gages. Stevens still offers the low-powered, mechanical chart recorders for …
Protecting Remote Monitoring Sites from Lightning Damage
Protecting monitoring sites from lightning damage is an important consideration for monitoring equipment and stations that are deployed in areas that are prone to lightning strikes. Even lightning that does not directly strike a site may cause damage by traveling through the ground and into buried sensors or cable. Proper planning for such events can …
