Applications and Industries where it is used

Electrical Panel

  • Where: Hour meters are used in electrical panels of generators, motors, and industrial machines.
  • Why: To record total runtime for maintenance scheduling, performance tracking, and operational cost analysis.

Building Management Systems(BMS)

  • Where: Hour meters are used in BMS panels to track the operating hours of HVAC systems, pumps, and other critical equipment.

  • Why: To schedule preventive maintenance, reduce downtime, and optimize energy management.

Generator / DG Set Panels

  • Where: Hour meters are used in Generator / DG Set panels to log the engine’s total running hours.

  • Why: To plan timely maintenance, track fuel usage, and ensure reliable generator performance.

Commercial Sub Metering / Retail Malls

  • Where: Hour meters are used in commercial sub-metering panels of retail malls to monitor usage time of shared equipment like HVAC, elevators, and lighting systems.

  • Why: To allocate operational costs fairly among tenants and support maintenance planning.
