Excellent capacitive level sensor factory in China? 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.

Rika weather stations are based around a data logger that measures the sensors, then processes, stores, and transmits the data. Data recording intervals are independently programmable. Our data loggers have wide operating temperature ranges, programmable execution intervals, and ample input channels for commonly used sensors. Most sensors can be measured directly—without external signal conditioning. RK900-01 Automatic Weather Station is used for atmospheric temperature, relative humidity, atmospheric pressure,wind speed & direction,solar radiation,light,rainfall,soil temperature and humidity parameters measurement.The station consists of various types of sensors, LCD screen, meteorological data collector, chassis, support and other parts.It can be widely used in meteorology, hydrology, agriculture, forestry, scientific research and other fields. Hunan Rika Electronic Tech Co.,Ltd is a privately held weather sensors and environmental sensor manufacturer and solution provider of environmental & weather monitoring for 10+ years.
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.
Hunan Rika Electronic Tech Co.,Ltd is a privately held sensor manufacturer and solution provider of environmental & weather monitoring for 10+ years.

The tipping bucket rain gauge is a remote rainfall measuring instrument composed of a sensor and a signal recorder. The sensor is composed of a water-bearing device, an upper tipping hopper, a measuring tipping hopper, a counting tipping hopper, and a dry reed switch. The recorder consists of a counter, a recording pen, a self-recording clock, a control circuit board, etc. Its working principle is rainwater from the top of the water socket into the water socket, into the water funnel, through the funnel into the hopper, when the volume of water reached a certain height (such as 0.1 mm), the hopper lost balance and overturned. And each time the bucket dump, the switch is connected to the circuit, to the recorder transmission of a pulse signal, the recorder control from the pen will record the rainfall, so reciprocating can be measured down the rainfall process.
