- The granular materials being processed flow into the upper storage hopper, here the feeding gate open, material is into weighing hopper, when the material weight in the weighing hopper, reaches the calibration value, the feeding gate close, the weighing unit analyze and confirm the value, here the net weight value plus the accumulated value and stored in the memory of total value. When the weight of the materials in discharging hopper is lower than low level (there is discharging space), the low level indicator sends signal, the weighing hopper gate opens, materials flow into the discharging hopper, here materials are discharged thoroughly, the discharging signal of weighing hopper disappears, the gate closes. After the weighing hopper becomes stable, it begins the next batch work.

- Precise. For gravity collecting, we use three rods suspension system to ensure a high precision.

- Credible. We adopt very few motion parts to ensure the smooth running.

- Intuitional. With double-screen display to show the net weight and gross weight.

- Safe. With excess value inspecting for weight and alarming function.

- Sanitary. With the cylinder casing to ensure the material thoroughly discharged and a small dust area, hence it has a good sanitation.

- Easy to maintain. All the parts can be checked and removed easily.

- Easy to mount. It can satisfy the mounting requirement to move the column

- Adopting the weighing & controlling instrument manufactured by Japan UNIPULSE Company or A&D company, with conformance of international quality authentication.

- Adopting LOGO program controller of German SIEMENS Company.

- Adopting pneumatic performing unit of British NORGREN Company, with conformance of international standard.

- Adopting high efficiency weighing sensor of German HBM Company.

- Adopting Lithium battery to supply power, thus prevent the data from losing when power is cut-off.
