With the control unit ModWeigh PPW.
The mass flow meter IPW S is used for continuous weighing of free-flowing bulk materials. The product flow rate is recorded and evaluated gravimetrically during the throughput.
The IPW S from MTS consists of a stable housing, the measuring chute with a special mounting system and the measuring chamber. The separation of product and measuring chamber secures the weighing system and allows also the use in dustproof Ex-zones (optional).
The stable mechanics and the dustproof housing guarantee high reliability and low maintenance cycles. The low height of only 415 mm allows quick installation even in existing and narrow conveyors.
The IPW S is often used for numerous weighing applications in closed dosing or conveying systems, such as capacity recording of internal material flows or for inventory control.
The IPW S mass flow meter is based on the principle of centripetal force.
The material flow rate is defined by the inlet of the housing and directed to the measuring chute. When the material arrives on the curved chute, a deflection of the material flow rate occurs from the vertical downstream axis into a circular flow. According to Newton’s second law of motion, a centrifugal force is exerted upon the product which then results in a counteracting force – the centripetal force – upon the suspension of the chute.
This force is recorded by a high-precision strain gauge load cell situated in the measuring chamber. Compared to the impact scales, the measuring principle of the mass flow meter allows for a continuous and exact weighing of very light bulk materials, such as powder or granules.
The mass flow meter IPW S has to be integrated into a conveying system in such a way that a constant output speed of the bulk material is guaranteed. Screw conveyors, rotary valves, bucket elevators, vibrating chutes, conveyor belts or scraper conveyors can be used to this effect.
