Capacitance level transmitter manufacturer and supplier right now? Because the dielectric constant ε1 of the liquid is different from the dielectric constant ε2 on the liquid surface, for example: ε1>ε2, when the liquid level rises, the total dielectric constant value between the two electrodes of the capacitive liquid level gauge increases accordingly Therefore, the capacitance increases. Conversely, when the liquid level drops, the ε value decreases and the capacitance also decreases. Therefore, the capacitive liquid level sensor can measure the unevenness of the liquid level by changing the capacitance between the two electrodes. The sensitivity of the capacitance level gauge mainly depends on the difference between the two dielectric constants. Moreover, as long as the stability of ε1 and ε2 can ensure the accuracy of the liquid level measurement, because the measured medium is conductive, the metal rod electrode is covered by an insulating layer . Capacitance level gauge is small in size, simple to complete remote transmission and dispatching, suitable for level measurement of corrosive and high-pressure media.

We offer two types of solar radiation sensor: silicon-cell and thermopile pyranometers, both types are now ISO 9060:2018 Class C rated (previously known as a second class). Silicon-cell solar radiation sensor model is excellent for applications that do not require high accuracy and with a limited budget. It is with faster response time and a more competitive price. But the solar pyranometer has higher errors under cloudy conditions. Our new cost-effective thermopile pyranometers feature a blackbody thermopile detector that provides a much broader and more uniform spectral response for better performance in all atmospheric conditions. Illuminance sensor for solar radiation measurement is widely used for shortwave radiation measurement in agricultural, ecological, and hydrological weather, and optimizing photovoltaic systems. Welcome to contact Rika on pyranometer sensor prices.
The automatic weather meter simultaneously measures atmospheric temperature, atmospheric humidity, air pressure, wind speed, wind direction, solar radiation, illuminance/ultraviolet rays, dust concentration and precipitation. The temperature, humidity and air pressure sensors are placed inside the radiation shield. The wind speed and direction of the ultrasonic principle. Rainfall detection by 24G radar can quickly detect rainfall and intensity. The system can be installed with a built-in GPS global positioning module and electronic compass, which can well indicate latitude, longitude and relative speed, and can calculate real and virtual wind speed and direction. It is especially suitable for installation on motion vectors, such as special vehicles or ships. Rika is specialized in weather sensors and environmental sensor providing aquaculture / weather / environmental monitoring solution, best weather station manufactuer.
Rain gauge is a meteorological instrument for determining the depth of precipitation (usually in mm) that occurs over a unit area (usually 1m2) and thus measuring rainfall amount. One millimetre of measured precipitation is the equivalent of one litre of rainfall per metre squared. We offer tipping bucket rain gauges, radar rain gauges, rain sensor switches and evaporation sensors, all of which are used in hydrometeorological monitoring and agriculture. Rainfall monitoring is very important in wide range of fields like meteorology, hydrology, agriculture, forestry, field monitoring stations and other industries, which enable people to prepare in advance. So we can imagine the importance of rain gauge. There are various types of rain gauge such as wireless rain gauge, tipping bucket rain gauge, automatic rain gauge station, etc.

The whole structure of the rain gauge is made of metal parts without rust, the inner wall should be smooth and round, the edge of the water bearing device should be free of burr or bruit and other defects, the shape is beautiful and elegant, the weather resistance is good, and the service life is longer. The shell of a common rain gauge is a metal cylinder, divided into two sections. The upper section is a water funnel with a diameter of 20 centimeters. In order to prevent rain splashing and maintain the area and shape of the container mouth, the mouth of the cylinder is made of hard copper with a blade shaped like straight inside and oblique outside. Place a water bottle in the lower section cylinder to collect rainwater. To measure, pour rainwater into a special rain cup to read the precipitation in millimeters. In the snowfall season, the storage bottle is taken out and replaced with a cylinder without funnel. The snowflakes can be collected directly in the rain-measuring cylinder and read after the snow melts. The snow can also be weighed and converted into millimeters according to the area of the cylinder.
