Zenith Pulsar Intelligent Pumping Station Controller

Pulsar's Zenith is a high specification pumping station management system. Pulsar's proven non-contacting ultrasonic technology provides almost all known pumping routines in an easy to use package. By combining advanced ultrasonic level measurement with the control and monitoring of pumps and providing many other control functions, it is possible to eliminate a PLC by using Zenith in a smaller station.
