Communication unit for smart series flowmeters: SMART COMMUNICATION UNIT
When connected with OVAL Smart series flowmeters, this communication terminal allows the operator to do such tasks as setting up, changing, or adjusting parameters, or reviewing obtained measurements, locally or from a remote location.
To this terminal, you may couple a personal computer operating on the Windows O. S. and the 4-20mADC signal transmission lines from the flowmeter. This setup enables display of multiple windows of the desired information on demand.
