Impact Weighers

Impact weighers provide a low cost, yet highly accurate, method of measuring the mass flow of dry solids and powders for inventory process control and can help you save thousands of dollars by reducing waste and improving product quality.

IMPACT WEIGHING AS A SOLUTION

Impact Weighers can be used as a scale or as a flow meter for solids to measure the flow or weight of bulk materials continuously. Impact scales can be installed in any mechanical conveying system. Use them as you would a belt scale. But you are not limited to conveyors only.

Typical prefeeds where an impact weigher would be suitable are:

  • Screw feeders
  • Bucket elevators
  • Rotary valves
  • Drag chain
  • Vibrating conveyors
  • Air slides

Our customisation services enable us to install solutions for any type of system. We won’t work against your established processes for the sake of making room for our implementations.

THE BENEFITS OF IMPACT WEIGHING

SITRANS WF solids flowmeters or impact weighers are designed so that the impact plate can only move horizontally. This means that from the total impact force only the horizontal component is measured. Other forces are ignored. This guarantees that changes in the weight of the sensing plate, due to material build-up or sensing plate wear, will not affect the zero or accuracy of the system.

Features and benefits:

  • Unique design allows installation even in the most difficult process environments
  • Measurement is not affected by changing the impact point on the sensing plate
  • Build-up on the sensing plate cannot influence the zero point
  • High reliability and low maintenance
  • Mechanical damping system absorbs shocks and damps vibration
  • Sensor allows some overload without damage to the system
  • Sensor is located in a dust-tight enclosure external to the process stream
  • Operates accurately in pulsating or surging flows
