Impact Weighers | Impact Flow Meters

An impact weigher continuously determines the momentary bulk flow rate and the total amount of bulk material – regardless of whether you are working with fine-grained or coarse-grained bulk, strands, powder or dusts.

Am impact weigh feeder furthermore controls the material input feed in order to achieve and maintain a preset bulk flow rate.

Impact weighers are great for applications with closed conveyors or for conveyors which are inapplicable for other weighing systems.

We are offering the following impact weighers (impact flow meters):

Impact Weigher  | Model DE 10 | for high flows

Impact Weigher | Model DE 10
for high flows

The DE10 impact weigher is designed to measure bulk solids flow rates from 5.0 tph to 800 tph. With its support system and corrugated spring arrangement, movement of the sensing plate is restricted to the horizontal plane. This movement is measured by a high-resolution sensor, which outputs a voltage that is converted into a noise-immune PFM digital signal.

Impact Weigher | Model DE 20 | for low flows

Impact Weigher | Model DE 20
for low flows

The DE20 impact weigher is designed to measure bulk solids with flow rates from 0.3 tph to 40 tph. The sensing plate is connected to a lever that is supported against a measuring spring. When bulk material hits the sensing plate, the force of impact can be measured by the displacement of the spring. A high-resolution sensor’s output is converted into a noise-immune PFM digital signal to measure this displacement.

Impact Weigher’s Principle of Operation:

Impact weighers are designed to measure the force generated by the impact of flowing material on a sensing plate. This force creates a mechanical deflection as it impacts the plate. This deflection is measured by a sensor and converted into an electrical signal.
