1. Overview
The GC-1A tank comprehensive parameter automatic measurement and control system is suitable for the measurement and control management of tank areas such as oil storage tanks, separation tanks, and settling tanks in the petrochemical industry. It can accurately measure the liquid level height of the medium in the storage tank, the position of the oil-water interface, the moisture content and temperature of each layer, and the thickness of the sludge at the bottom of the tank. There is an alarm function for important indicators. Ultimately achieving precise automatic inventory management. This system can flexibly measure 1-8 storage tanks simultaneously; Display the oil layer, transition zone, water, and sludge of the storage tank in different colors; Display the corresponding moisture content of each height level of the storage tank in the form of a curve; Convenient query and printing of historical data and curves; Liquid level over limit alarm; The system can remotely view the detection results and has a confidentiality function. It completely breaks the traditional measurement mode of oil tanks in the petrochemical industry tank farm, making it truly realize the comprehensive measurement automation of multiple indicators. The explosion-proof design of this system is based on the performance and characteristics of the product, adopting both explosion-proof and intrinsic safety explosion-proof design.
2. Function and Features

Firstly, set the parameters: mandatory parameters include the number of storage tanks, rope length, address, moisture content voltage curve, and the location where the record file should be saved. After completing the settings and exiting, restart the program to enter working mode. If two storage tanks are selected for operation, the main interface will automatically adjust to the layout shown in the following figure:
During the measurement process, the arrow indicating the tank on the diagram displays the measurement process. After the measurement is completed, placing the mouse over the indicated tank area will display a visual curve graph,
As shown in the following diagram:
