METER BASE LOGGER (MBL-40)

The Silent Partner Meter Logger is a safe, easy to operate logging solution for residential use. Completely housed in a meter base adapter, the logger is easily installed between the existing revenue meter and the meter base. Rugged, watertight construction means that the logger is resistant to harsh environments and vandalism. Unlike other loggers, the MBL actually measures line to line voltage in addition to line to neutral. This is important, because phase shifts can cause the sum of the two line to neutral voltages to be greater than the actual measured line-to-line voltage. Internal rechargeable batteries continue logging in the event of a power failure.





Features:

  1. Record RMS voltage for L1-N, L2-N, L1-L2, and RMS current for L1-N, L2-N (12-bit resolution).
  2. Installs behind regular revenue meter – no need to enter the customer’s house.
  3. -40°C temperature range for extreme weather conditions.
  4. Versatile neutral connection works with all sockets

Application:

  1. Investigate over charging, under charging, or inaccurate revenue billing meters.
  2. Monitor voltage sags, swells, and current profiles for L1 and L2.
  3. Customer complaint diagnosis.
  4. Monitoring vacant buildings.
  5. Peak Shaving and Load Management.
  6. Find loose neutrals
