Hydrochloric acid concentration meter

1 SDT600Hydrochloric acid concentration meterprinciple
Using a sound frequency signal source to excite a metal tuning fork and causing it to vibrate freely at the center frequency, which corresponds to the density of the liquid in contact. Therefore, by analyzing the frequency, the density of the liquid can be measured, and temperature compensation can be performed to eliminate the system's temperature drift; And the concentration is calculated based on the relationship between the corresponding liquid density and concentration.

IIHydrochloric acid concentration meterapplication
Mainly used for production process control and measurement in low corrosion liquid industries, such as oil field refining, food and beverage, paper industry, chemical acid and alkali solutions, wine industry, salt industry, printing and dyeing, pharmaceuticals, evaporative crystallization and other industries.

8 SDT600Acid-base concentration meterInstall
Due to the requirements of the production process, it is often installed on sites with harsh working conditions. In order to minimize the adverse working conditions of instruments, they should be installed in areas with minimal impact and vibration. When working in flowing pipelines, they should be installed in locations with low flow rates. For this reason, our company has made improvements to the probe. Only by ensuring that the liquid fully contacts the sensor and fully considering the on-site conditions can it achieve its expected accuracy indicators.

Pay attention to the following items during installation:
In terms of instrumentation:
The product must be suitable for easy installation in a convenient location, taking into account full contact between the liquid and the sensor. If the liquid in the pipeline is not fully filled, it should be installed below or on the side of the pipeline, otherwise it will affect the measurement accuracy.
