Understanding Maximum Demand Ammeters: Types, Applications, and Why Eutroniks Leads the Way
In today’s energy-driven world, especially across the Middle East, monitoring peak electrical demand is crucial for efficiency, cost control, and system safety. As businesses aim to optimize load usage, avoid penalties, and maintain compliance with DEWA, ADDC, and other regulatory standards, Maximum Demand Ammeters (MDAs) have become an indispensable tool in the design of switchboards, generator panels, and energy management systems.
🔍 What is a Maximum Demand Ammeter?
A Maximum Demand Ammeter measures the highest average current drawn over a set period, typically 15 minutes. Unlike standard ammeters that provide real-time readings, MDAs capture and retain peak demand events, giving operators a critical understanding of their system’s load profile.
These meters feature:
- A thermal bimetallic movement to measure the mean RMS current
- A red slave pointer that locks onto the maximum recorded current
- A manual reset knob to reset the recorded peak
- Robust shock-absorbing design for industrial environments
At GoSwitchgear, we proudly supply Eutroniks Maximum Demand Meters, engineered specifically for industrial and commercial applications in the GCC region.
🧱 Types of Maximum Demand Ammeters: Mono vs. Bi-Structure
1. Mono-Structure Maximum Demand Ammeters (SQ Series)
A Mono-Structure MDA uses a single thermal bimetallic movement to measure and display the peak demand over the specified time period.

Applications:
- Basic transformer station monitoring
- LT feeder panels
- Solar pump control systems
- Sites that only require peak load recording, not instantaneous values
2. Bi-Structure Maximum Demand Ammeters (SIQ Series)
A Bi-Structure MDA cleverly combines two movements:
- Thermal Bimetallic: For maximum demand over time
- Moving Iron: For real-time RMS current reading
📸 Bi-Structure Image:
Applications:
- Generator control panels (real-time and peak monitoring)
- Data centers and UPS systems
- Critical process industries where both instantaneous and historical readings are necessary
- Energy management systems require redundancy

🏢 Where Are Maximum Demand Ammeters Used?
Across the Middle East, particularly in the UAE, Saudi Arabia, Oman, and Qatar, MDAs are vital components in:
| Industry/Application | Purpose |
|---|---|
| Power Distribution Panels | Transformer protection, peak monitoring |
| Industrial Manufacturing | Load profiling, machinery current monitoring |
| Renewable Energy Systems | Solar and wind system demand logging |
| Commercial Building Management | Prevent overbilling due to excess demand |
| Oil and Gas Facilities | Real-time load awareness and historical peak tracking |
| Public Utilities and Substations | Demand charge compliance and energy auditing |
The thermal inertia of the bimetal movement makes these meters ideal for indicating prolonged load surges, helping facilities avoid costly penalties and system failures.
| Application | Recommended Type | Description |
|---|---|---|
| Transformer Load Monitoring | Mono / Bi | Avoid overload, log peak demand |
| LT Feeder Panels | Mono | Basic current profiling |
| Diesel Generator Panels | Bi | Real-time + thermal tracking |
| Factories and Warehouses | Mono | Long-duration load tracking |
| Data Centers | Bi | Real-time precision needed |
| Solar Pump Control Panels | Mono | Seasonal peak logging |
| Utility Substations | Bi | Demand-based billing compliance |
| Switchboards with SCADA/EMS | Bi | Redundant analog feedback to digital systems |
