Nanjing Pulaisen Instrument Co., Ltd.’s NK caustic soda online analyzer and RP online analyzer are two products custom‑designed for alumina production processes. They measure critical process parameters—caustic soda concentration and the RP/αK ratio. To withstand the high temperature, high alkalinity, high pressure, and corrosive, scaling‑prone conditions typical of alumina plants, these instruments feature a unique design that ensures reliable operation even under extreme conditions, while delivering real‑time, accurate measurement data to customers.
The Smartdiver sludge‑layer interface meter meets the needs of various industries for measuring sludge‑layer stratification interfaces in thickening tanks, settling tanks, and separation tanks, and is widely used in alumina‑industry separation tanks and CCD counter‑current washing tanks.
The sonar flow meters and ultrasonic density meters manufactured by Nanjing Pulaisen Instrument Co., Ltd. are widely used in the alumina industry both domestically and internationally. The sonar flow meter breaks with conventional measurement techniques by employing advanced sonar‑based principles, thereby revolutionizing traditional installation methods: it eliminates the need for pipe‑penetrating installations, allowing the probe to be mounted directly on the exterior of the pipe. This approach avoids the economic losses associated with production shutdowns caused by instrument installation, as well as subsequent maintenance challenges. Similarly, the ultrasonic density meter represents a breakthrough over traditional nuclear‑radiation‑based measurement technologies. By leveraging the attenuation of ultrasonic waves, it measures the density of process slurries without handling radioactive materials, bypassing complex approval procedures, posing no environmental risks, and requiring no special installation conditions—while delivering precise measurements with zero drift.
