SZ-BU120 Bubble Water Level Gauge Introduction: The SZ-BU120 bubble type water level gauge is a high-precision water level sensor. It uses a micro piston pump as a blowing and pressure inducing device to convert the static water pressure at the underwater measuring point into the pressure value of gas, which is then led to the water surface through a measuring tube and sensed and processed by a pressure sensor to achieve water level measurement. Due to the fact that pressure sensors measure the pressure of compressed air without the need to come into contact with the measured liquid, their long-term stability is extremely high. The SZ-BU120 bubble type water level gauge has the characteristics of high precision, high reliability, high intelligence, no gas cylinder, no logging, no maintenance, anti vibration, and long service life. It is particularly suitable for monitoring flowing water bodies, large, medium, and small rivers, reservoirs, or industrial wastewater with serious water pollution and strong corrosiveness that is inconvenient or expensive to build wells in, such as water conservancy and hydrology, upstream and downstream of dams, oceans, groundwater levels, petroleum, chemical, sewage treatment plants, urban drainage pump stations, etc. characteristic: 1. Non contact measurement, high accuracy, good stability, and easy maintenance; 2. Easy installation, no need to build a well, and not affected by floating objects on the water surface; 3. It has zero point automatic correction function, which can completely eliminate zero drift error; 4. It has analog output and digital communication interface, which is convenient for users to use; 5. Wide voltage design, with reverse connection protection, overvoltage and overcurrent protection, and lightning surge absorption capability; 6. Configure LCD display screen and input keyboard to intuitively display real-time water level and operate flexibly; 7. Automatic cleaning function to ensure unobstructed airway; 8. Cycle storage of 10000 measurement records; 9. Adopting Modbus communication protocol for easy integration with various data acquisition devices. Technical parameter Power supply voltage: 10-30VDC. Standby current: ≤ 4mA Average current: ≤ 10mA (measurement interval of 1 minute, RS485 or SDI-12 output) Range: 20m Resolution: 1mm Measurement accuracy: ± 0.03% F.S Long term stability: ≤± 0.1% F.S. per year Water level change rate: 60cm/min Measurement interval: 1-60 minutes can be set, default is 1 minute Communication interface: RS 485 or SDI-12 Analog output: 4-20mA Measurement tube specifications: inner diameter 3/outer diameter 8 Measuring medium: water (river, lake, groundwater, etc.), special liquid can be customized Working temperature: -10~50 ℃ Storage temperature: -40~60 ℃ Environmental humidity: less than 95%
