Water level sensor refers to the point to be measured water level parameters in real time into a response to the electrical signal instrumentation. Water level sensors are mainly used in water plants, refineries, chemical plants, glass factories, sewage treatment plants, high-rise water supply systems, reservoirs, rivers, oceans and other water supply pools, water pools, water treatment pools, water wells, water tanks, water tanks, oil wells, tanks, tanks and a variety of static and dynamic liquid level measurement and control. Water level sensor There are many types of water level sensors, different water level sensors work differently, applicable to different places, a brief introduction to the principle of several types of water level sensors. Float type water level transmitter: float type water level sensor is the magnetic float to float, is designed according to Archimedes buoyancy principle. Float water level sensor is the use of tiny metal membrane strain sensing technology to measure the water level, boundary level or density of the liquid, it can be in the work of the field key to carry out the routine setting operation. Float type water level sensor: float type water level sensor consists of magnetic float, measuring conduit, signal unit, electronic unit, junction box and installation parts, the general specific gravity of the magnetic float is less than 0.5, can be floated above the liquid surface and along the measurement of the conduit up and down, the conduit is equipped with a measuring element, which can be measured under the action of the external magnetic water level signal is converted into a signal directly proportional to the change in the level of the resistance signal, and will be converted to signal output by the electronic unit. Convert the electronic unit into a signal output. Ultrasonic water level sensor: This is a vibration frequency higher than the sound wave mechanical waves, vibration generated by the transducer chip in the voltage excitation of ultrasonic waves, ultrasonic waves in the liquid will produce significant reflection to form a reflection into the echo. Therefore, ultrasonic waves are used as a means of detection, generating and receiving ultrasonic waves. Hydrostatic water level sensor: Hydrostatic water level sensor utilizes the measurement principle of liquid static pressure, adopts diffusion silicon piezoresistive pressure sensor with stainless steel isolation diaphragm as the signal element, accurately measures the static pressure of liquid level which is directly proportional to the depth of the liquid level, and converts it into 4-20mA current, 0-5V voltage, RS485 and other signals after professional signal conditioning circuitry to realize accurate measurement of the water level and depth. Precise measurement of water level and depth. Users can choose the appropriate water level sensor according to the site-specific conditions. Hydrostatic water level sensors have high dexterity, fast response speed, high accuracy level, stainless steel sealed steel structure and high waterproof level. Hydrostatic water level sensor also has a small size, easy to install and put and so on. Hydrostatic water level sensor cable with high temperature and corrosion resistance. Hydrostatic water level sensor is the ideal instrumentation for water level measurement.
