Computer Connectivity
ModWeigh instruments can be connected to a computer withan RS232 connection. Data can be sent to
the PC at a preset rate. The data sent can be set up using macros.
There is also a command line interface which allows any of the settings and data to be read or written.

Configurations
There are three principle configurations for gravimetric flow measurement and control systems. These
are Weight Loss, Modified Weight Loss and Weight Gain.
All configurations have the same basic components of a flow regulator and weigh hopper.
