Why the SmartTrol™? The SmartTrol™ is a remote instrument designed for flow rate monitoring, totalizing, and batching. It has an 8-digit, 0.55-in bright alphanumeric display. The two inputs accept up to 1,000 pulses per second (pps) of digital count and are combined into a single count that can be used to provide a two-stage relay output for valve control.
