Application introduction of water level sensor

 The site is equipped with a glass level gauge for reference. When the liquid level can also go up and down, the liquid level gauge can be lowered to the lower limit of the glass liquid level gauge, the transmitter output can be adjusted to 4mA through zero, and then the liquid level sensor is raised to the upper limit of the liquid level gauge, and the range is adjusted to 20mA However, please note that if you need to compare with the glass liquid level gauge, the effective liquid level detection range of the capacitive liquid level gauge must be greater than the effective liquid level display range of the glass liquid level gauge, and the installation elevation should be the same, otherwise it will not be able to communicate with each other within the full range. correspond.

Not only that, the sensor has also developed intelligent temperature and water level sensors based on multi-industry monitoring points to escort the water level monitoring of sewage wells in hydropower stations.

The transformation ratio of the voltage and current transformers used in the installation of the drum water level can be set arbitrarily, depending on the physical and chemical properties and cleanliness of the medium. For conventional differential pressure transmitters and float-type liquid level transmitters, it is also necessary to adjust the contact medium part. The material is selected; the noise filter can also effectively suppress the interference of the AC servo drive to other equipment. This measure can effectively suppress the above-mentioned interference phenomena.

The structure is simple and can be controlled by a detection and alarm device with characteristics such as transmission rate, error, output current, protection, and starting device. Test: The three temperature transmitter control technologies can be composed of ordinary, pure, semi-pure, ultra-pure, stable temperature transmitter, temperature difference transmitter and mutual difference transmitter. Controls the offset of the water level sensor. The liquid level signal is a kind of signal that prompts the liquid level safely, and has the following functions: the change of the control signal of the solenoid valve.

The intelligent water level sensor is a fully sealed submersible intelligent liquid level measuring instrument with an all-stainless steel design. This product adopts high-stability, high-reliability piezoresistive OEM pressure sensor and high-precision intelligent transmitter processing circuit using precise digital temperature compensation technology and nonlinear correction technology. It is a high-precision liquid level measurement product. The waterproof cable is sealed with the housing, and the ventilation tube can be used for liquids for a long time. The integrated structure and standardized output signal provide convenience for on-site use and automatic control.

The sensor directly enters the liquid and measures the height from the end of the transmitter to the liquid level. It has high precision and is easy to use. After long-term aging stability evaluation, the performance is stable and reliable. It can be widely used in fire water tanks, urban water supply and drainage, sewage treatment, river reservoirs and other fields. .

The height of the liquid is measured by the pressure difference generated by the gravity of the liquid itself. According to the physical and chemical properties and cleanliness of the medium, the traditional differential pressure transmitter and the float level transmitter, select the material that contacts the medium; the calibration of the intelligent differential pressure transmitter.

Application of Rain Gauge in Agricultural Weather Station

图片
In traditional agriculture, people have very limited ways to obtain farmland information, mainly through manual satellite measurement, which requires a lot of manpower. wide application. In monitoring crop irrigation, soil air changes, livestock and poultry house environmental conditions, and large-scale surface testing, collecting temperature, humidity, wind, atmosphere, rainfall, soil moisture, soil nitrogen, phosphorus and potassium content and PH value, etc. In terms of data, sensing technology is playing an increasingly important role in the development of smart agriculture. Collecting information from various sensors can help farmers find problems in time and accurately capture the location of the problem. Through the use of wireless sensor networks, labor consumption and the impact on the farmland environment can be effectively reduced, and accurate crop environment and crop information can be obtained. In this way, scientific monitoring and reasonable planting can be achieved, ...

Tips for regular maintenance of tipping bucket rain gauge 1. The tipping bucket rain gauge is outdoors for a long time and the operating environment is very harsh. Therefore, the inner wall of the rain port of the instrument should be frequently wiped with a soft cloth to keep the rain port clean. If there are foreign objects such as leaves in the rain port, it should be cleaned in time to keep the waterway unblocked. When the instrument is not used for a long time, a cover should be placed on the instrument ring to protect the rain-bearing opening. The long-term work of the instrument is generally cleaned up once a month and once every three months. 2. Check-in time after each heavy precipitation process to prevent overflow. During the precipitation process, when the amount of precipitation may exceed the measurement range due to a large amount of precipitation, water should be drained in time during the intermittent period of precipitation. It is expected that there will be dusty we...
