Overview
Online density/concentration meters are used to measure the concentration of liquid media in tanks and pipelines. Concentration measurement is an important process control in product production technology, and tuning fork density/concentration meters can be used as indicators for other quality control parameters such as solid content or concentration values. It can meet various measurement requirements of users for density, concentration, and solid content.
Product Details
working principle
Online density/concentration meter uses a sound frequency signal source to excite a metal tuning fork and make it vibrate freely at the center frequency, which is related to the density of the liquid in contact. Therefore, by analyzing the frequency, the density of the liquid can be measured, and then temperature compensation can be carried out to eliminate the system's temperature drift; The concentration value at 25 ℃ can be calculated based on the relationship between the density and concentration of the corresponding liquid.
