WITS Certified

The S2000 is a fully WITS (Water Industry Telemetry Standards) compliant device proving its  interoperability with other WITS-approved master stations and field devices. WITS certification ensures the device has:

  • A single protocol to support multiple vendors
  • Secure authentication between RTUs and master station
  • A common configuration and application programme
  • Flexible configuration options
WITS Certified

Configuration and user interface

All Seprol devices are easily and highly configurable; the standard method for configuring commonly used features reduces the possibility of configuration problems. The built-in IsaGraf IEC1131-3 configuration and application tool means that Seprol devices can be configured using a PC or laptop. All the RTU’s features, inputs and outputs can be managed through any web browser using the embedded web server and the intelligent user interface.

Configuration and user interface

Pump controller

The S2000micro is available with an integrated feature-rich pump controller application, which makes each unit capable of controlling three or two fixed or variable speed pumps respectively. The pump controller application allows you to perform a wide range of wastewater functions, including level control and monitoring, periodic cleansing, burst and blockage detection and remote resets, plus much more. The clean water pump controller enables reservoir, pressure, flow and timed control of the pumps.
