Product Description

Ultra 4 offers users a high level of sophistication and advanced features for level, flow, and volume. Suitable for liquids and solids, the Ultra 4 features 4 relays that are assignable by type for high/low-level alarms and/or pump run on/off control.

The new multifunctional display allows for easy set-up and configuration, as well as on-screen trend monitoring with echo profiles and trend graphs available to be viewed on-screen. The controller can be wall or fascia mounted and includes HART, Profibus, and Modbus digital communication options, the convenience of onboard Micro SD card allows for extended data logging.

The unit offers built-in volume calculations based on standard tank shapes as well as advanced pump control and open channel flow measurement functions.

• Pump Control
• Open Channel Flow & Level
• Chemical Dosing
• IBC Tank Level
• Storage Tank Levels
• CSO & Sewer Network Monitoring
