Liquid loss-in-weight feed rates are dependent on tank size, scale size and selected metering device. A wide range of pumps and tanks can be combined with a suspension scale or platform scale using K-Tron's SFT III weighing technology for the gravimetric feeding of liquids. In this application, the liquid is discharged from the hopper by weighing the liquid being fed and regulating the speed of the feeding device.
The loss-in-weight signal from the hopper load cell / scale is sent to the pump and the pump speed is adjusted to achieve constant massflow. The complete liquid loss-in-weight system (feeder, scale, pump, piping) is available in special skid mounted designs which are completely portable for movement throughout the plant. K-Tron Systems Group specializes in designing and integrating both liquid and powder loss-in-weight systems for applications such as extrusion. |
