Master Control Unit

The GUARD LEVEL® Master Control Unit (MCU) is the core of a reliable monitoring and alarm system. The MCU guarantees ultimate performance and top-rated safety in tanks, vessels and in potentially hazardous work areas. It works in harmony with a number of Bergan products.

This “go to” Intrinsically Safe and versatile unit supports up to three completely independent systems; High Level (HL) and Overfill Level (HHL) and tank gauging. It’s also available in three physical sizes depending upon required number of I/O.

The HL and HHL’s well-designed mimic panels are comprised of bright amber and red LEDs for easy visibility. There is also a separate alarm acknowledge switch, and differing frequency piezo buzzers with adjustable volume control. The gauging section’s hardened and extended temperature-rated embedded computer with the powerful (Intel) i7 processor runs both Windows 10 operating software and GUARD LEVEL® Cargo Monitoring Software (CMS+) application software.

This CMS+ user interface is intuitive with a highly configurable 19-inch LCD touchscreen display that can also be console mounted.

Additionally, the MCU can connect to our Guard Power® Uninterruptible Power Source (UPS) and, optionally, a Wi- Fi for remote slave display. Plus, the MCU provides multiple communication ports capable of Ethernet broadcast and Modbus communication over serial or Ethernet connections.
