Mass Flow meters



◆Continuous bulk solids measurement in belt conveyor systems.
◆Suitable for flow rates up to 15,000 t/hr.
◆Accuracy up to ± 0.5 %.
◆Also legal-for-trade-version.
◆Simple and quick installation.
◆Type BEM - designed modularly, suitable for any belt width.
◆Types BEP/BED - weighing platforms, suitable for IEC belt widths.

Single-Idler Belt Weighers are used for continuous acquisition of flow rates and totalized amounts. They are especially designed for integration into continuously operating belt conveyors enabling accuracies of up to ± 0.5% to be achieved.
They can be employed for a whole variety of tasks:

◆Throughput and consumption measurement in production plants.
◆Accountability of stored and retrieved amounts.
◆Load limit alarm.
◆Batching, in load-out stations.
◆Legal-for-trade weighing.
◆Prefeeder control.

Their rugged design ensures a highdegree of reliability and availability. We have the right Belt Weigher for every Belt Conveyor. For Multi-Idler Belt Weighers designed for higher accuracies, see separate Spec Sheet.

The standard single-idler belt weigher comprises:
◆Weighing module or platform for accommodating user's idler set.
◆Overload-protected load cell(s)with high degree of protection.
◆Cable junction box for connection of sensors, and all fixing elements required for mounting.

For speed measurement, various speed transducers e.g. friction wheel tachometers, are available as options.

〈Operating Principle〉
Belt Weighers are used to measure continuous material flows of varying amounts.
Load cells acquire the weight of load on particular belt sections. A speed transducer measures the belt speed. The product of these two variables is the current flow rate. Integration of flow rate determines the totalized amount of material.
If belt weighers are not equipped with speed measurement system, belt speed
is not acquired. In the secases, weighing electronics use the constant speed value set by parameter. However, this method can adversely affect the accuracy.
