In contrast, multi-point meters—also known as multi-customer metering systems (MCMS)—are designed for larger buildings with many tenants or sub-circuits. These systems consolidate data from multiple units into a single, central metering panel. This makes them a cost-effective and space-efficient solution for properties such as commercial towers, institutional campuses or mixed-use developments. MCMS are also easier to integrate with building automation systems (BAS), energy management systems (EMS), and sustainability reporting platforms.

Multi-point meters also offer better scalability. As a building expands or tenant needs evolve, additional circuits can be added without the need to install separate meters for each new tenant. This allows property owners and facility managers to maintain a streamlined infrastructure while still capturing accurate, real-time data across all areas of the building.

Here’s a side-by-side comparison of both options:

Revenue vs Check Metering – Ensuring Accuracy & Compliance

Understanding the difference between revenue metering and check metering is essential for property managers, developers and facility operators who are responsible for tenant billing, energy benchmarking and system performance monitoring.

Revenue-grade meters are designed and certified for legal billing purposes. These meters meet stringent accuracy requirements set by regulatory bodies such as Measurement Canada and ANSI C12.20, ensuring that tenants are billed fairly and precisely for the energy they consume. In multi-residential and commercial applications, using revenue-grade meters is often a legal requirement to allocate utility costs across tenants or business units.

Revenue-grade meters are also tamper-proof, calibrated to high precision, and typically come with features like demand tracking and time-of-use measurement. They are commonly used in buildings where tenant billing is required or where energy costs need to be passed through to occupants with complete transparency.

On the other hand, check meters are used for internal monitoring and energy management, not for billing. These meters provide valuable insights into system load patterns, equipment performance and energy waste, making them ideal for benchmarking, load balancing and verifying energy savings initiatives. However, they are not certified for billing purposes, and using them to invoice tenants can result in compliance issues or legal disputes.

If your goal is to allocate costs across multiple tenants or departments, a revenue-grade meter is mandatory. If you’re tracking internal systems for efficiency, a check meter may be all you need. In many cases, both types of meters are used in parallel: revenue meters for billing, and check meters for monitoring, diagnostics and sustainability reporting.

Quick comparison of key differences:

  • Revenue-Grade Meters – Certified for billing by Measurement Canada & ANSI C12.20, suitable for legal tenant billing and energy cost allocation.
  • Check Meters – Used for internal monitoring and energy management, but not suitable for invoicing tenants or legal cost recovery.

Key Takeaway: If billing tenants, always choose a revenue-grade meter to ensure compliance, accuracy and peace of mind.
