The mobile chemical liquid filling vehicle, mobile liquid automatic drum filling equipment, and liquid automated metering equipment are quantitative mass metering systems developed by Yantai Hongjian Measurement and Filling Equipment Co., Ltd. for the production and sales metering of liquid chemical products. The unit of measurement is kilograms. It is mainly suitable for quantitative drum filling, quantitative truck loading, and reactor feeding of various liquid products such as plasticizers, toluene, solvent oil, edible oil, acetic acid, pharmaceutical intermediates, gasoline and diesel, formaldehyde, etc. The system uses temperature detection and density compensation methods to ensure metering accuracy during the liquid filling process, overcoming measurement errors caused by temperature changes. The metering accuracy can reach 0.2%.

Performance characteristics of the mobile chemical liquid filling vehicle, mobile liquid automatic drum filling equipment, and liquid automated metering equipment:

1. Wide temperature detection range (-20°C to 160°C);

2. Uses signal processing and transmission technology to ensure stable and reliable flow signals, guaranteeing metering accuracy;

3. The equipment employs automatic pressure compensation technology to overcome the drawback of metering accuracy being affected by changes in the oil storage tank level;

4. Uses oil-gas separation technology to automatically separate gas from oil and gas during unloading from tankers or ships, improving metering accuracy;

5. Data is saved after power failure for future reference; in case of sudden power failure, restarting the system can display the metering values and drum count before the power failure;

6. Capable of printing daily totals, overall totals, instrument parameters, metering values, oil delivery time, date, etc. Chinese character printers or wheel printers can be selected;

7. The equipment uses automatic identification technology with self-diagnosis for faults and automatic alarm for incorrect operations;

8. Features automatic fault protection and correction functions;

9. Equipped with standard communication interfaces for networking multiple instruments, allowing remote computers to monitor the operating status of multiple instruments and perform real-time data collection. Sales reports and statistics can be generated at any time, enhancing the company's modern management level;

The mobile liquid drum filling cart system consists of a quantitative metering control instrument, pipeline flow transmitter, temperature sensor, etc. During liquid transportation, it collects flow signals and temperature change signals in real time. Using the specific gravity of water for calculation, the DN40 caliber metering system can fill approximately 200 kg per minute when the pump flow reaches 12 m3/h, significantly saving time, labor, material resources, and reducing drum loss, with very precise metering. The system's metering accuracy is better than 0.2%.
