Nett Weighers (Product pre-weighed in a vessel above the bag).

• Very fast. The next weighing cycle can start as soon as the weigher doors have closed, whilst the currently filled bag is being dropped and a fresh one fitted into the clamps. Nett weighers will operate at 10 cycles per minute minimum for most materials, and 15 cycles per minute with excellent accuracy can be achieved with certain materials and bag weights.
• Very accurate. The inflight amount of material is smaller than a gross weigher, due to a shorter distance between the feeder outlet and the weigh hopper. The weigher is always a constant distance from the feeder outlet, ensuring repeatability. There is also virtually no opportunity for the operator to tamper with the weigher parts during filling.
• Large headroom required. For most nett weighing systems, at least 5 or 6 metres headroom is required, which would include a 1000 Litre surge hopper at the top.
• More expensive. A weigh hopper and more ancillaries / metal parts are required compared to a gross weigher, which increases cost.

Gross Weighers (Product weighed in the bag). Note that most electronic weighing in the bag will tare the empty bag off and technically be a nett weigher.

• Low headroom. Discounting the height of the top surge hopper, a gross weigher and feeder can take up less than 2 metres of height (including the conveyor).
• Lower cost.No weigh hopper is used and therefore less ancillaries / metal parts are required, reducing the cost.
• Slower than nett weighers. The next weighing cycle cannot start until a fresh bag is fitted into the clamps. Generally the speeds that can be achieved are up to 8 cycles per minute with good accuracy, depending on the material. For an application where accuracy is of less importance, higher speeds can be achieved, of up to 12 cycles per minute (may involve fast feed only).
• Slightly less accurate. The operator can fit the bag at an angle, which will affect the inflight amount. The inflight amount of material is higher due to a longer drop between the feeder outlet and the bag. It is easy for the operator to tamper with the weigher parts during filling, which will affect cut-off and the subsequent inflight adjustment for the next weighing cycle.
• Can be in a mobile format more easily than nett weighers.
