Automatic liquid caustic drum filling metering equipment

The automatic liquid caustic soda drum filling metering equipment performs real-time temperature tracking and density compensation of the medium during the metering process to ensure measurement accuracy is unaffected by temperature variations. It directly measures the mass of the medium, with the unit of measurement being kilograms. It allows for direct loading onto vehicles without the need for cumbersome procedures such as tare weighing, weighing, loading, and unloading of packaging drums. The automatic liquid caustic soda drum filling metering equipment consists of a quantitative metering control instrument, pipeline liquid flow transmitter, temperature sensor, and other components. During liquid transportation, it collects flow signals and temperature change signals in real time. The control instrument initially inputs the standard density of the liquid at 20°C, then synchronously converts the flow and temperature signals using a conversion coefficient to calculate the mass of the liquid in kilograms. When the preset quantitative delivery amount is reached, it automatically stops the pump and closes the valve, achieving quantitative mass measurement with an accuracy of 0.2%. The instrument can also print the number of kilograms of liquid delivered.

Filling procedure of the automatic liquid caustic soda drum filling metering equipment:

Empty drums on the ground or in vehicles are exempt from tare weighing, and one person can operate the system. After setting the filling amount (kilograms/liters) via remote control, automatic timing control, or the start key of the quantitative control instrument, the handheld filling gun is placed into the drum opening. Filling automatically stops when the preset amount is reached, and the filling gun is then moved to the next drum for the next filling cycle. Operators can flexibly control the filling rhythm. The handheld automatic filling equipment eliminates the need for tare weighing of empty drums and the weighing and handling of filled drums, significantly improving filling efficiency and avoiding disputes and losses caused by underfilling or overfilling due to human factors.
