LPG Filling Scale
The LPG filling scale is an LPG filling system with a metering function, which functions to inject the LPG into the container according to the set weight. The filling scale consists of a liquid filling gun, a weighing platform, and a control system. The system is mature in structure and stable in performance, and does not pose a hazard to the operator’s environment. It is widely used in all walks of life requiring LPG filling.
The LPG electronic filling scale uses a pressure-sensing sensor to collect data using a 24-bit high-precision AD conversion chip produced by Texas Instruments, using a high-precision Cortex-M3 series core processor from STMicroelectronics for data analysis, using a balance scale and corresponding Piping is designed to reduce data interference. The new human-computer interaction interface, net weight, gross weight, error, and other parameters, and on-site control status are displayed at a glance. The system parameters are softwareized, and the operator can conveniently and efficiently set various parameters on the touch screen.

Standard mode: automatic peeling, automatic identification of cans (5 types can be set), and according to the cans, automatically judge the LPG filling weight.
Net weight mode: automatic peeling, filling with the weight of pure LPG.
Gross weight mode: Filled by the weight of the can and the weight of the LPG.
Lock function: Enter the password to unlock to prevent other unrelated personnel from operating.
Calibration function: The calibration scale guarantees the accuracy of the filling scale.
Total Query: Query total gas consumption, total amount, cumulative bottle number, and filling time.
100-filling record query function: query the tanks, gas consumption, amount, unit price, total gas consumption, and end time of the last 100 guns.
Anti-cheat function: The weight of the weighing platform is lightened due to human intervention during the filling process, the filling is suspended, and the alarm is automatically issued.
Blue Sky Communication Protocol: Connect to the blue sky background system.
Batch inquiry function: You can query the cumulative number of bottles and total air consumption per batch of the last ten batches.
Peeling function: remove the weight of the cylinder and the weight of the connecting tube.
