Over View
The PCL600 Series batch controllers use temperature correction to calculate the volumetric flow for liquids at standard reference conditions. The PCL600 Series is ideally suited to custody transfer applications and includes the API/ASTM equations covering general petroleum products and LPG. The PCL600 Series is direct RTD input or 4-20mA temperature input.
