Dynamic Density Meter
The Only In-line Real-Time
"Dynamic" Bulk Density Meter
Overview
The BatcHHouse Dynamic Density Meter is the process industry's only in-line, real-time density meter providing an output representing the dynamic density of the dry solids material flowing through it.
Improve your process and product quality by using this complete sensor/control solution. The real-time output representing dynamic bulk density can be used in a feed-forward or feed-back mode to monitor or control a single flow stream's density or maintain a specified density of a material as the control variable of a blend of "light/heavy" materials.
The Dynamic Density Meter is designed for use in a manufacturing or packaging process.
- Processing - To maintain precise density in applications where varying bulk density could affect product quality
- Filling - To maintain consistent fill level in packaging
The Technology
The Density Meter system consists of (1) a Bulk Solids Pump Volumetric Feeder and material hopper on load cells that is in-line in the process. Above the feeder is an automated gate valve (2) that receives material from the process.
In normal operation material flows through the gate valve and feeder into the process. To calculate density the controls close the gate valve on a demand or timed basis. As the level in the feed hopper lowers, a weight reading is triggered at a defined level. Upon taking a successful weight reading the gate valve opens. This entire process is completed in seconds and in-line without any interruption of material output. A measurement can be taken as frequently as every 5-10 seconds.
Density is calculated by dividing material weight by the volume of the material.
Density (lbs/ft3) = Weight (lbs)/Volume (ft3)
As indicated, the Dynamic Density Meter weighs the complete stream of material (no sampling) in its natural flow or dynamic state of flow. The real-time output signal equals the dynamic bulk density of the material in motion.
