What are the functions of liquefied gas filling scale
Date: 2025-11-13Read: 31
Liquefied gas filling scale is a specialized measuring equipment used in the filling process of liquid gases such as liquefied petroleum gas (LPG) and liquefied natural gas (LNG), integrating functions such as weighing, control, safety protection, and data management. Its core purpose is to achieve precise control of filling volume, improve filling efficiency, and ensure operational safety. The following are the main functions and detailed instructions of the liquefied gas filling scale:1、 Core measurement function
-
高精度称重
-
Dynamic/Static WeighingSupport real-time dynamic weighing (such as measuring while filling) or static weighing (stable measurement after filling) during the filling process, with an accuracy typically ranging from ± 0.1% to ± 0.5%.
-
Multi range adaptationDifferent filling ranges (such as 5kg, 15kg, 50kg) can be set to adapt to different scenarios such as household bottles and industrial cans.
-
Peeling functionAutomatically deduct the weight of empty bottles and display the net filling amount directly, avoiding manual calculation errors.
-
auto-calibration
-
Built in standard weight calibrationThrough the built-in calibration program, the deviation of the weighing sensor is automatically corrected using standard weights to ensure stable accuracy for long-term use.
-
temperature compensationBased on the characteristic of liquefied gas density changing with temperature, automatically adjust the measurement value (such as converting standard volume at 20 ℃) to avoid measurement deviation caused by temperature fluctuations.
2、 Automated control function
-
Pre set filling volume control
-
One-click settingPreset the target filling amount (such as 14.5kg ± 0.1kg) through instruments or upper computer software, and automatically stop when the filling reaches the set value.
-
Segmented fillingSupport multi-stage filling (such as rapid filling in the initial stage and slow replenishment in the final stage) to reduce liquid impact and improve filling accuracy.
-
Anti overflow protection
-
Linkage of liquid level detectionLinked with the liquid level sensor, when the filling volume approaches the preset value, the filling speed will be automatically reduced; Immediately close the valve when the set value is reached to prevent liquid overflow.
-
Emergency stop buttonEquipped with a manual emergency stop button, it can immediately interrupt filling in case of abnormal situations (such as leakage or equipment failure).
-
Automatic valve control
-
Pneumatic/electric valve driveControl the opening and closing of the filling pipeline through solenoid valves or pneumatic actuators, with a response time of ≤ 0.5 seconds, ensuring fast and accurate start and stop.
-
Valve status monitoringReal time display of valve opening and closing status, triggering an alarm and stopping filling in case of malfunction.
3、 Security protection function
-
Anti static design
-
grounding protectionThe metal components such as the scale body, filling pipeline, and valve are grounded with conductive tape to prevent static electricity accumulation and explosion.
-
Explosion-proof certificationCompliant with explosion-proof standards such as Ex d II CT4, suitable for flammable and explosive places (such as liquefied gas stations).
-
Leakage detection and alarm
-
Gas concentration sensorDetect the concentration of combustible gases in the filling area, trigger an audible and visual alarm when exceeding the limit, and automatically shut down.
-
Abnormal pressure monitoringMonitor the pressure of the filling pipeline, and stop filling immediately in case of sudden pressure changes (such as pipeline blockage or valve failure).
-
Overload/Unbalanced Load Protection
-
Weight limit alarmWhen the filling volume exceeds the preset upper limit or the empty bottle weight is abnormal, it is prohibited to start filling and an error message will be displayed.
-
Stability testing of scale bodyMonitor the horizontal status of the scale body through sensors, and automatically shut down if the tilt exceeds the limit.
4、 Data management and traceability function
-
Filling record storage
-
local storageThe built-in memory can record information such as filling time, bottle number, filling volume, and operator, and supports querying by date and bottle number.
-
Data exportExport data to a USB flash drive or upper computer system through USB, RS485, or Ethernet interfaces for easy statistical analysis.
-
report generation
-
Custom ReportSupport the generation of daily/weekly/monthly filling volume statistics reports, loss analysis reports, etc., to assist enterprises in optimizing inventory management.
5、 Human computer interaction and convenience functions
-
large screen display
-
LED/LCD display screenReal time display of filling volume, target value, remaining quantity, fault codes, and other information, which can be viewed remotely by operators.
-
Multilingual supportSupports multiple language interfaces such as Chinese and English to meet the usage needs of different regions.
-
touch screen operation
-
Graphical interfaceSimplify the operation process by setting filling parameters, querying historical records, and calibrating equipment through the touch screen.
-
Permission ManagementSet different permissions for administrators, operators, etc. to prevent misoperation or data tampering.
-
wireless communication
-
Wi Fi/4G moduleSupport remote monitoring of filling status, receiving fault alarms, updating software, and achieving unmanned management.
-
Mobile APPReal time viewing of filling data and receiving abnormal notifications through a mobile app to improve management efficiency.
