How the OMB Net Weigher Works

The OMB NET WEIGHER provides the most accurate way of filling free-flowing products because of the sensitive electronic. 

loadcells and intuitive control system. This protects you from over and underfills, and assures your end-user gets the correct amount of product every time. The Hermetically Sealed APE-7 loadcells pre-weigh one batch in an internal weigh hopper so it is ready to dump when your operator installs a bag.


OMB Net Weigher comes fitted with SMART GATE technology designed to overcome the issues associated with the small apertures required to deliver accuracy and maintain flow rate. It may be supplied with an infeed hopper from our range or with adaptions to suit your existing overhead bin.

The advantage of our OMB net packer is that whilst the operator or an automatic bag placer is managing the bags, a precisely weighed batch is being loaded into an internal weighing hopper. The batch is typically ready when a bag is inserted and a dump of the internal hopper occurs. After the bag fills, the OMB automatically senses its hopper is empty and starts a new batch. The end result is improved bag weights and greater throughout. In simple terms gross packers weigh the material into the bag, there is no internal hopper, whereas the Net Weigher Pre-Weighs the
product prior to filling into the bag.

This system can be linked with other Bradwood feeding devices such as augers, vibratory feeders, belt feeders, etc. for non-free-flowing products. (see page 5 for Optional infeed).

We can configure our packers in a duplex mode where 2 packers service one bag outlet, or in a multiple packer environment where a common infeed silo services 2 or more packers. These special configurations may be implemented to increase production rates, especially for products with higher bulk densities or larger bag weights. The OMB Net Weigher Has The Lowest ‘Cost Of Ownership’ Because It Will Provide Year Round, Low
Maintenance, Precise Filling Of Open Mouth Bags.
