Advanced Tank Weighing & Process Control Solutions
Tank weighing
Tank weighing from a single tank to a tank farm can be handled with GR320 & GR323. The R320 and R323 provide basic weighing functionality at the tank. The two high current isolated outputs can provide local control which could be used for level control for example. The communications port can be used to work back to a PC or in a larger installation multiple indicators can be configured in a ring network, saving on cabling.
Ring Networking
The R320 and R323 support can be configured into a ring network back to a computer using R232.
- Connect up to 31xR320/R323s into a ring network.
- Simple setup with the R300 Viewer.
Benefits:
- Uses only one communication port on the computer.
- Significant savings on communications cabling.
Ideal for:
- Tank farms.
- Multiple silo and bin weighing applications.
- Multiple scale applications.
- Process Control applications.
