Description

The BFM136 monitors up to 12 three phase circuits, 18 two phase or 36 single phase circuits, or any combination of single, two or three phase circuits. This flexibility makes the BFM136 perfect for multi-tenant facilities such as residential projects, office buildings, data centers and shopping malls.

The compact BFM136 is designed to easily fit into existing panel boards or be flush mounted nearby, thus eliminating the need for expensive retrofit projects or for allocating extra space for the device.

The BFM136 monitors up to 36 currents via High Accuracy Current Sensors (HACS). Each HACS measures and reports the current consumed by each of the branch circuits at the panel board. For billing purposes, single or multiple circuits can be defined for each customer. This flexibility allows a simple reassignment of circuit groups without wiring changes, and allows for easy changes when tenants move in and out. Main panel board or load center installation makes for a valuable saving of both time and money.

The BFM136's user-defined and easily configured alarm system enables users to take predictive maintenance action in order to avoid unnecessary outages.

Billing & Time Of Use (TOU)

Tariffs vary according to different criteria, such as the week day, holiday, season or consumer type (private home accounts in multitenant buildings, businesses, industry etc.). The BFM136 provides data for TOU billing in compliance with the rates set by the local electricity supplier. Unlike some other meters on the market, the BFM136 stores the TOU information on its non-volatile memory, protecting the data in case of communication loss or power outage.

Commercial Buildings

Many commercial buildings have a single electricity connection, while the building owner/manager is responsible for distributing the electricity to the tenants. Since charging the tenants based on floor area is no longer acceptable, an accurate, reliable and flexible system should be applied. The BFM136 is specially designed for such cases, allowing the owner/manager to easily monitor the consumption in a small footprint.

Using the BFM136 with SATEC Expertpower™ software will allow issuing invoices to the tenants based on real consumption.

Data Centers

Energy consumption of data centers is constantly rising, following the increase of computing performance. Monitoring the PUE (Power Usage Effectiveness—Total Facility Energy divided by the IT Equipment Energy) is essential. According to the US DoE (Department of Energy), data centers can achieve energy savings of 20-50% by utilizing today's best practices, including “continuously monitor energy” and “monitor energy at all levels.”

The practice of monitoring energy is becoming prevalent and modern data centers now include rack level monitoring at the design stage. The BFM136 monitors up to 36 single phase loads, which is ideal for this task, allowing for energy saving and offering high reliability.

Industrial Plants

Typically, industrial plants have many loads that are fed from the same MCC. It has been proven that online monitoring of the consumption down to a single load level results in energy saving of up to 30%.

The BFM136 is the most compact and efficient method to monitor several loads located up to 200m from the device, with uncomparable accuracy. The use of single device rather than separated meters makes it easy to install and maintain as well as single point for communication.
