Application Case Of Tuning Fork Density Meter in Photovoltaic Energy Cell Production

During the production process of a large solar cell, it is necessary to monitor the concentration of isopropanol solution online and control the concentration percentage. Convert the measured concentration signal into a current, set the upper and lower limit control values on the human-machine interface. When the liquid density is lower than the lower limit value, the lower limit port of the control table outputs a control voltage to drive the mother liquor control valve to open. When the liquid exceeds the upper limit value, the control instrument controls the upper limit valve to open, reducing the flow of diluted liquid into the mixed liquid to the upper limit value but not lower than the lower limit value, The tuning fork density meter is placed on the production line to achieve automated measurement and control.
