Online hydrochloric acid concentration meter

　　Online hydrochloric acid concentration meterSuitable for online measurement of hydrochloric acid concentration in pipelines or storage tanks in caustic soda plants. The concentration meter can be inserted and installed, and the data can be displayed on site or remotely transmitted to DCS. The product is maintenance free and has a long service life.

Details introduction: It uses a sound frequency signal source to excite a metal tuning fork and make it vibrate freely at the center frequency. This frequency 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 a temperature of 20 ℃ can be calculated based on the relationship between the density and concentration of the corresponding liquid.

　　Online hydrochloric acid concentration meterSuitable for various installation methods such as pipeline installation or container wall insertion installation, both dynamic and static can be measured, and installation methods include flange and clamp. Flange type and clamp type.
