IN-PROCESS WEIGHER / BATCH WEIGHER
An In-Process Weigher, also known as a Batch Weigher comes closest of all dynamic weighing methods to static weighing.
Installed into your process, the In-Process/ Batch Weigher can be set to either:
- Monitor, or
- Control the flow rate of product.
The analogue output can be used to ratio control additional products.

Selection Criteria
In-Process/ Batch Weighers are generally used for
- In-Process Control,
- Control flow rate into process,
- Batch Out Loading.
Advantages
- Easy calibration.
- High Accuracy.
Disadvantages
- Pulses product flow.
- Requires more headroom than Weigh Belt Conveyors or Weigh Feeders.
To select the correct In-Process/ Batch Weigher for your application, contact us.
We will need you to provide us with some basic information
- What is the application?
- What accuracy is required?
- Flow Rate?
- Physical height available?
- The process?
For a more detailed advice contact us. to request an In-Process Weigher Questionaire.

Method of Operation
Product is fed into a weigh hopper through a Single Position Feed Gate.
The Feed Gate closes while the product is weighed and discharged from the hopper. The cycle then repeats. The feed device is selected for the product being handled. (e.g. this could be a screw, belt or vibro feeder and so on.) In-process Weighers provide continuous weighing with better accuracy than other dynamic weighing methods.
Accuracy
Expect ± 0.20% or better
Flow Rate
Flow rates up to 2,000tph.
Available Output
The In-Process/ Batch Weigher will provide:
- The total of the material passing, and
- Instantaneous Flow Rate.
- An analogue output signal can be used to control other equipment.
- RS232, RS422/485 Communications
- Pulse Output
The analogue output signal acts as a reference signal to control the addition of one or more additional products.
