Acid Alkali Concentration Meter Online

Working Principle

An inline tuning fork density meter works on the principle that a tuning fork’s resonant frequency decreases as the density of the surrounding liquid increases. The acid or caustic concentration meter uses piezoelectric crystals to drive the tuning fork into vibration at its natural frequency, which is then detected and processed by electronics. Through phase-shifting and amplification circuit, the fork body is stabilized on the natural resonance frequency. When the medium flows through the fork, the change of resonance frequency is caused by the change of medium quality.

Challenges in Inline Acid Alkali Concentration Measurement

Corrosion to wetted parts caused by strong acids (concentrated hydrochloric acid, sulfuric acid) and alkali (strong sodium hydroxide) may shorten life expectancy and compromise on its optimal performance. Anti-corrosion materials like Hastelloy and polytetrafluoroethylene are recommended in demanding operation environments.

Advantages of Lonnmeter Inline Acid Concentration Analyzer
