The article mainly talks about the principle of water level sensor. Those who are interested in children’s shoes come and learn it.
The water level sensor is an instrument that can convert the water level parameters of the measured point into the corresponding electricity signal in real time. It is mainly composed of a fully sealed isolation membrane oil-filled sensor and a built-in high-performance microprocessor. Drift, etc. carry out a full range of digital correction processing, and have HART communication protocol output and analog output. It has the characteristics of high accuracy and excellent stability. It can realize two-way communication during the on-site diagnosis process, and can be used in urban power supply, water conservancy and hydropower, metallurgy, petrochemical, etc.
The principle of the water level sensor: The water level sensor in the container transmits the sensed water level signal to the controller. The computer in the controller compares the measured water level signal with the set signal to obtain the deviation, and then according to the nature of the deviation, The electric feed water valve issues “open” and “close” commands to ensure that the container reaches the set water level. After the water intake program is completed, the computer in the temperature control section sends an “open” command to the electric valve that supplies the heating medium, and the system starts to heat the water in the container. When the set temperature is reached. The controller issues the command to close the valve, cuts off the heat source, and the system enters the heat preservation state.
The water level sensor has high precision, good long-term stability, wide measurement range, strong reliability, industry-leading laser all-welded structure, and multiple protections such as anti-shock, anti-radio frequency, anti-lightning design, over-voltage, reverse polarity, current limit, etc. Advantages, it is widely used in water plants, oil refineries, chemical plants, glass plants, sewage treatment plants, high-rise water supply systems, reservoirs, rivers, oceans, etc. for supply pools, distribution pools, water treatment pools, wells, water tanks, water tanks, In oil wells, oil tanks, oil pools and measurement and control systems for static and dynamic liquid levels of various liquids.
