Virtual Hydromet - Sensors

The SEN-EP is a Evaporation measurement sensor used to monitor the water evaporation from Surface water, dams, lakes, pools, aquatic ponds in simulation of open PAN Evaporation measurement.

Pressure Sensor with integral cable contains a vent tube for Barometric pressure compensation. Comes with 30 to 300mm range.

Continuous and contact-free snow depth measurement. Reliable sensor for extreme conditions, Robust sealed ceramic membrane. Correct measurement during snowfall and snow drift. Protective shield against ice and snow hangings. High measuring accuracy. Integrated temperature compensation. Energy-saving sensor operation. Standby between the measuring phases. Simple sensor integration

Visibility sensor designed by Dr. Sten Lfving is used to make direct measurements of visual range. This sensor is a robust backscatter visibility sensor. The sensor is equipped with a membrane ventilator preventing from water intrusion because of under pressure during sudden temp decrease.

We are offering 4-component net-radiation sensor. This is a 4-component net-radiation sensor that is used for scientific-grade energy balance studies. The instrument has separate measurements of solar (short wave or sw) and far infra-red (long wave or lw) radiation. Major improvements relative to comparable instruments include weight (reduced), solar offsets in the lw signal (reduced), ease of leveling (high, because leveling assembly is included).

We are offering pyranometer for global radiation. A pyranometer is an instrument for measuring solar radiation received from a whole hemisphere. It is suitable for measuring global sun plus sky radiation. The pyranometer sensor measures global solar radiation (sun plus sky) for a spectral response graph. This instrument is used extensively in meteorological studies, passive solar system analysis, irrigation scheduling, hydrologic studies and many other environmental studies. The standard system consists of a weatherproof enclosure which contains the data logger and power supply, and comes complete with a solar panel, tripod stand and sensor. The data shuttle is a pocket-sized device that can be used to download and transport the data to a personal computer. Albedo measurement: provided as per requirement

We are offering pyrgeometer sensor. This is a sensor that can be applied for far infra red (fir) radiation observations. The main application is in meteorological outdoor experiments. The scientific name of this instrument is pyrgeometer. This is heated, which improves measurement accuracy because it prevents dew deposition. This has a special housing, which makes it possible to include a transmitter, or amplifier. For additional information on the application, use and specifications of regular pyrgeometer, brochure and manual can be consulted.

MiniOFS is designed by Dr. Sten Lfving is used to make direct measurements of visual range. The sensor is sensitive for particles in a zone about 25 cm ahead of the location of the sensor wholimit the visibility in the air. These particles are normally the microscopic water particles constituting fog, but they may also be snowflakes, raindrops or air pollutants. But the most indications of low visibility are because of fog or snow.

This is a low-cost anemometer, which utilises proven ultrasonic technology to provide wind speed and direction data via one serial or two analogue outputs. To confirm correct operation, outputs are transmitted together with an instrument status code.

With a robust, corrosion-free polycarbonate housing, this small, lightweight wind sensor is recommended for use in harsh environmental conditions and is particularly suited to marine & offshore (ships, data buoys) and land based installations. The WindSon has no moving parts, offering maintenance-free operation in a wide range of applications.
