The acid-base liquid filling metering pump consists of a quantitative metering control instrument, pipeline 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 conversion coefficients to calculate the mass 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.

Product Features:
1. The acid-base liquid filling metering pump utilizes advanced microcomputer technology and a unique design to achieve dynamic tracking over a wide temperature range (-20°C to 160°C) and density compensation. The computer automatically tracks changes in oil temperature and density, adjusting the delivery volume in real time to ensure that the delivery quality remains unaffected by temperature and density variations. The measurement accuracy exceeds the national standard of Class 0.2 (measurement accuracy ≤ 0.2%). 
2. The high-capacity main chip enables faster computing speed, higher accuracy, more stable performance, and simpler operation. Data is never lost, and it can be equipped with a large-screen LCD display, remote control operation, and computer networking for scientific management, among many other advantages. 
3. The acid-base liquid filling metering pump allows users to view or print data such as delivered oil volume, daily cumulative volume, and total cumulative volume at any time.
4.  In the event of an unexpected power outage and restart, it displays the last delivered oil volume to avoid disputes with customers.
5. It can be started or stopped via wired remote control. It is suitable for edible oil, chemical liquids, lubricants, emulsions, food, and other fields. 

Working Procedure of the Acid-Base Liquid Filling Metering Pump:

Empty barrels on the ground or in vehicles can be weighed without tare removal, and one person can operate the system. After setting the filling amount (kilograms/liters), control is managed via a remote control, automatic timing control, or the start key of the flow control instrument. The handheld filling gun is placed into the barrel opening, and filling automatically stops when the preset amount is reached. The filling gun is then moved to the next barrel for the next filling cycle. Operators can flexibly control the liquid filling volume and filling rhythm. The handheld automatic barrel filling device eliminates the need for weighing empty barrels and handling heavy barrels, significantly improving filling efficiency and avoiding disputes and losses caused by human factors such as underfilling or overfilling.
