Chemical Concentration Meter

The concentration measuring instrument features a chemical concentration sensor resistant to corrosive fluids. It's a valuable inline process sensors for real-time concentration monitoring. Its ease of use, accuracy and efficiency all leaves it an ideal inline instrument in various applications.

Product Features

● Real-time concentration or density measurement for direct product process control;
● Accurate and reliable 5-digit (4 decimal places) real-time readings;
● Measured physical parameters are converted to standard 4-20mA current signal;
● Offer real-time current and temperature readings;
● Enable direct parameter setting and commissioning on site by simply entering into menu;
● Feature pure water calibration, fine-tuning and temperature compensation functions;
● Selectable anti-corrosion material for wetted parts;

Working Principle

It utilizes an acoustic signal source to excite a metal tuning fork, leaving it to vibrate at its resonant frequency. The resonant frequency correlates to the density of contacted liquids. Then liquid density could be measured through frequency analysis, and temperature compensation is applied to eliminate system temperature drift. For concentration measurement, the concentration value at 20 °C is calculated based on the relational formula between the density and concentration of the corresponding liquid.
