Momentum 25F Feeder

Delivering superior weight based flow control

Ideal for blending applications, the Momentum 25F delivers continuous uninterrupted flow at a desired rate. It continuously adjusts to maintain the operator or host computer selected set point within 0.5% of full scale.

Instead of conventional impact measurement using a flat deflection plate, the Momentum 25F determines flow by measuring the forces necessary to redirect the incoming material flow from near vertical to horizontal along a specially designed curve chute - a patented, change in momentum method of measurement. This method overcomes the inherent inaccuracy caused by scattered, unpredictable material flow caused by impact style measurement.

As well, the weight based design of the Momentum 25F eliminates the inherent errors of volumetric feeding, since weight based measurement is unaffected by varying material densities or moisture content.

Features

Models from 4 to 80 metric tons/hour with standard turndown ratio of 10:1 ie. from 100% to 10% of capacity.

Maintains weight based accuracy +/- 0.5% of full scale throughout standard operating range.

Easy calibration by suspending a known test weight on feeder - rather than cumbersome check weighing.

Standard Modbus, optional DeviceNet, Profibus, and Ethernet networks.

Inlet to outlet offset results in minimum headroom requirement for maximum installation flexibility.

Each unit has its own dedicated Fuzzy-PID based controller for greater reliability.

For applications with multiple feeders, built in networking allows convenient centralized recipe-based control using BlendView or your PC and Comptrol's DDE linking software.

Suitable for use in unheated environments

Suitable for use in Class II, Group G, Div. 1 locations. Controller must be in a non-hazardous location.

Delivers uninterrupted flow for maximum blending accuracy.

Optional stainless steel contact surfaces, or as fully stainless steel units.
