The SmartTrol™ is a remote instrument designed for flow monitoring and batching. It has an 8-digit bright alphanumeric display. The two pulse inputs (A and B) will accept up to 10,000 pulses per second of digital count. The inputs can be monitored separately or can be combined into a single count which can in-turn be used to provide a relay output for valve control or signal indication that a batch is complete. The controller can display volume total, rate of flow or grand total for up to two Neptune water meters equipped with any of the above transmitters. The SmartTrol is designed to be panel mounted and when mounted in the correct enclosure is NEMA 4 rated.
