Energy, Utilities & Infrastructure Overfill Alarm Systems

Energy production, utility operations, and critical infrastructure facilities rely on precise tank monitoring to ensure safe, continuous operation. The Meco AST Overfill Alarm provides a reliable audible alert when aboveground storage tank (AST) liquid levels reach a preset high point, helping operators prevent overfill incidents and maintain uninterrupted workflows.

From power generation plants to utility storage systems, Meco alarms are trusted to deliver dependable alerts that protect equipment, personnel, and operations.

Energy and infrastructure environments demand alarm systems that are robust, intrinsically safe, and easy to maintain. The Meco AST Overfill Alarm is a battery-operated audible alarm designed to operate reliably under continuous or intermittent monitoring conditions.

When tank levels reach the alarm threshold, a 100 dB pulsating audible signal alerts operators, enabling immediate action to avoid spills or operational disruption.

Overfills in energy and utility storage tanks can lead to costly equipment damage, safety risks, and regulatory non-compliance. The Meco AST Overfill Alarm provides a clear, immediate warning before tanks exceed safe operating levels.

Key features for energy and infrastructure applications:

• Adjustable float switch for precise alarm level settings
• Push-button test to verify alarm functionality before filling
• Manual reset after high-level activation
• Compatible with both protected and standard ASTs

This straightforward design supports operational reliability and ensures consistent, repeatable procedures.

Facilities handling fuels, chemicals, or industrial fluids require alarms that meet strict safety and regulatory standards. The Meco AST Overfill Alarm is Certified Intrinsically Safe to ANSI/UL 913, suitable for hazardous locations commonly found in energy and utility operations.

Compliance includes:

• NFPA 30A
• UL 2244
• UFC requirements

These certifications support both operational safety and regulatory adherence.

Meco alarms provide flexibility in power configurations to meet diverse facility requirements.

• 9 V battery operation with ultra-low power draw in non-alarm conditions
• Optional 12 V intrinsically safe line power for continuous operation
• Minimal maintenance and long service life

Important: Certain Canadian regions require wiring to a 12 V source. Always check local regulations before installation.

In facilities using double-wall or secondary containment tanks, the Meco alarm can be configured as an interstitial leak detector. Custom probe lengths can be specified to meet tank manufacturer requirements, adding an extra layer of operational safety. 

Energy and utility facilities often operate 24/7 under variable environmental conditions. The Meco AST Overfill Alarm is designed to function reliably under these demanding conditions.

Operating temperature ranges:

• 9 V Alkaline: −4°F to +130°F
• 9 V Lithium: −40°F to +158°F (recommended for extended life)

No power draw during normal operation ensures long-term reliability with minimal maintenance.

Meco AST Overfill Alarms are widely used in:

• Power generation fuel storage
• Utility-owned storage tanks
• Critical infrastructure fluid containment
• Emergency backup fuel systems
• Industrial process and storage tanks

These applications benefit from fast, actionable alerts that help maintain safe and continuous operations.

Whether you are specifying a single alarm or multiple units for multiple tanks, our team can help you select the right configuration for your energy, utility, or infrastructure application. 

Meco provides intrinsically safe AST overfill alarm systems for energy, utility, and infrastructure facilities throughout the United States and Canada.
