Liquid Loss-in-Weight Feeders

Liquid loss-in-weight feeders provide accurate gravimetric feeding of liquids and pastes in continuous or batch operations

The liquid loss-in-weight feeding system is the most accurate and reliable solution for a wide variety of liquids and many different viscosities and temperatures

The liquid or paste to be fed is metered by a pump outside the scale area. The feed pump is selected based on the feeding capacity required. Coperion K-Tron’s SmartConnex® control system allows for single or multi-component control.

For systems with a central controller, interface modules have been built into the control module.

Liquid Feeder Designs

Coperion K-Tron offers two weighing options for liquid gravimetric feeders. On the K-ML-D5-P (above right) the storage tank is mounted on a platform scale. The scale housing is stainless steel and completely closed.

With the K-ML-P model (below right) the storage tank is mounted in a 3 point weighing system.

Both feeder models feature the exclusive, patented Smart Force Transducer (SFT) with vibrating wire technology and an on-board microprocessor.

To keep the pump isolated from the weighing area, a flexible connecting line is required between tank and pump. Depending on the application a hose made of silicone, natural rubber or PTFE may be used.

Depending on the needs of the application, additional equipment such as heaters or mixers can be supplied as well.
