Quantitative loading

The hardware of this system's quantitative loading control unit mainly consists of an integrated intelligent controller module, a liquid crystal operation panel (including an operation keypad), and other auxiliary devices (terminals, power supplies, explosion-proof boxes, etc.). This hardware design and composition confer many inherent advantages to the entire unit, as it differs from traditional systems composed of single-chip microcontroller integrated circuits.

The main functions are as follows:
The quantitative loading system is commonly used in the loading operations for liquid, ammonia, liquefied gas, and other chemical products. Currently, manufacturers in the domestic chemical storage tank industry often opt for the quantitative loading system for their loading operations. The superior performance of the quantitative loading system during loading operations has deeply won the favor of all customers.....
Quantitative Loading System
Parameter Setting Function
The fueling instrument can adjust fueling parameters according to the oil delivery requirements, either through remote monitoring on a computer or by setting the parameters on the fueling instrument. These parameters include: flow coefficient, lead time, overshoot, valve opening delay time, fluid density, etc.
(2) Quantitative Oil Distribution Control
Once the working parameters of the fueling meter are confirmed, it will automatically complete the fuel dispensing process according to the set program. The fuel dispensing will automatically stop once the set volume is reached.
(3) Spill Oil Protection Function
Stop oil discharge upon spillage.
(4) Grounding Protection Function
If the system is not grounded, oil discharge cannot be initiated. If loading is in progress, stop the oil discharge.
(5) Power Failure Protection Function
During an unexpected power outage during oiling, the oiling parameters can be saved, and the oiling can be resumed upon power restoration.
(6) Data Collection Function
The vehicle loading instrument can collect flow meter pulse signals or standard current signals, can be connected to thermistor temperature signals via a transmitter, and can also be connected to switch signals such as anti-spill and static grounding clips.
(7) Sequential control function for valves and pumps
At the start of loading, valves (pumps) are sequentially opened according to the scheduled time order. Once the predetermined loading quantity is reached, valves (pumps) are sequentially closed according to the scheduled time and order to complete the automatic loading operation.
(8) Emergency Stop Function
The emergency stop button is installed on both the trucking instrument and the remote monitoring screen. In case of an emergency on-site during fueling, the operator simply needs to press the emergency stop button to immediately halt the fueling process.
(9) Remote and On-site Real-Time Monitoring Functionality
The vehicle loading instrument is equipped with a high-brightness STN LCD display. During on-site operation, it displays the fueling process and the status of related equipment in real-time. For remote operation, the remote monitoring computer synchronizes with the vehicle loading instrument to display the fueling process and the status of related equipment in real-time.
(10) Remote/On-site Oil Supply Mode Conversion Function
Under normal circumstances, oil is generally distributed remotely via a master station, but oil distribution on-site is also possible as needed. Each loading instrument in this system is a complete unit for measurement, control, and display, operating independently of the master station.
Power supply function for on-site instruments
This vehicle-mounted instrument also provides power output terminals, supplying both 24VDC and 220VAC power types for on-site instruments such as flowmeters and valves.
(12) Communication Networking Function
This vehicle loading instrument is an open system with robust communication and networking capabilities, enabling connection with the host computer and other systems via Ethernet or RS485 networks.
(13) Equipment Self-Check Function
The system automatically detects the working status of the loading instrument, and the monitoring computer can remotely monitor the working status of the loading instrument. In case of a failure in the loading instrument, the system will automatically trigger an alarm.
(14) Operation Permission Settings
This vehicle loading instrument can be set with a three-level six-digit operation password; correct password levels are required for operation.
(15) Password recognition feature for fuel billing documents
Once the customer who is picking up oil enters the corresponding bill of lading number and password on the operation panel, the system automatically identifies the customer's name, the quantity of oil to be picked up, vehicle number, and other parameters.
This project employs cabinet-style installation for convenience and aesthetic appeal on-site.
