LPG Filling Scale

The LPG electronic 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 24Bit 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 display at a glance, the system parameters are softwareized, 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), 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, and 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.
