Liquid alkali concentration online detector refractometer liquid density meter

Liquid alkali concentration online detector refractometer liquid density meter

By adopting the principle of critical angle detection, it can be installed on pipelines or tank container walls of different diameters to monitor and control the concentration of liquid alkali. It can directly display the percentage concentration (Percent) or user-defined units, and is not affected by impurities such as color, turbidity, bubbles, solid particles, etc. of liquid alkali. It has high-precision automatic temperature compensation function. Adopting a split design, full screen anti-interference design, and direct conversion and processing of photoelectric signals. Abandoning the drawbacks of being intolerant to vibration and high temperatures, the accuracy of online measurement is guaranteed and the service life of the instrument is extended. Built in fiber optic transmission system, with seismic performance and high stability, built-in temperature sensor and desiccant to effectively monitor the operation of the concentration meter. It is a liquid alkali concentration measuring instrument. Compared with traditional manual laboratory methods, the measurement is faster, more accurate, and the results are clearer. It can automatically perform temperature compensation, display on site, and can be remotely transmitted to the recorder through analog signals (4-20mA) or communication signals (RS485) for real-time data storage, printing, traceability, and other functions; It can also be monitored or controlled through remote transmission to PLC/DCS/frequency converter.
