Power meters measure utilities like electric, gas, or water to increase building performance. With apower meter, users can get granular data on the use of energy of a building. Such granularity can reveal any equipment or systems adding to energy waste. Submeters can be used in any type of building, from manufacturing to apartments.Metersmake it easy to visualize and optimize energy usage.
Single Circuit vs Multi-Load
Single circuit power meters are designed to monitor one single or one 3 phase circuit. These meters are typically used for measuring a specific panel, mimicking the building main, or a single piece of industrial equipment.
Multi-load power meters are designed to measure multiple single or 3 phase loads at one time. These meters are typically used to support energy management strategies that require moregranular data．使用一个多负载仪表比几个单负载仪表占地面积小得多。监测多个负载的能力意味着一个多负载仪表比一个单负载仪表每个测量点的成本要低得多。
双电压输入仪表允许用户从一个功率表测量两种不同的服务类型和电压水平。这允许用户测量大的三相负荷，如空气处理单元或冷水机组，与测量建筑物内任何一点单相照明负荷相同的仪表。用户也可以测量120V和480V，例如，在双电压输入的多负载表上同时测量。
Benefits of Power Meters
Power meters enable users to track and eventually optimize energy use. Trending data and real-time readouts reveal inconsistencies, spikes in usage, and even potential energy waste. With web software, it is even easier to analyze real-time data of power meters.
With electricity costs on the rise, there is a need for accuratetenant-specific metering．在租户的情况下，电表有助于确保租户根据他们的实际用电量正确收取费用，而不是在租金中包含大宗价格。用这种方法来衡量公用事业能让租户对他们的能源使用更加谨慎，并允许他们减少公用事业的使用。
Another benefit of power meters is fault detection. Fault detection allows for a proactive monitoring mindset. Facility managers are alerted when systems don't operate efficiently or properly. Fault detection helps identify issues before they lead to failure, including:
- Overheating
- Leaking
- Systems needing repair
- Required maintenance
Power meters also enable demand response. Demand response allows for better asset management and access to utility programs. A power meter can indicate if a utility is under high stress during peak hours, allowing for a facility manager to reduce demand. Depending on the area, there are rebates for using utilities during hours of lowerpeak demand．电能表揭示了减少电力需求的最佳方法。
