KEP Meter ST1-MANIFOLD-FC 2 Channel Manifold Controller and Flow Computer

KEP Meter ST1-SUM-FC (ST1SUMFC) Rate/Total Flow Computer for Sum of 2 Flowmeters in Liquid Applications

The ST1-SUM-FC Flow Computer can monitor the actual sum of two flow rates and two totals of any liquid. (Common applications include compound flowmeters) Flow alarms are provided via relays and data logging is available via analog (4-20mA) and serial outputs.
