Meter Reading
In a CMMS like ServiceGrid, a meter reading is a numerical measurement of asset usage (e.g., runtime hours, cycle counts, mileage, energy consumption, pressure, temperature) logged against a specific asset to shift maintenance from calendar-based to usage-based triggers.
In shop floor maintenance, technicians log the current meter value in the CMMS work order at the start of a Preventive Maintenance (PM) task to establish a baseline for the next service interval. The system automatically spawns a preventive work order when the meter crosses a configured trigger threshold (e.g., lubrication every 1,000 cycles). Batch Meter Reading features allow efficient updating of multiple assets simultaneously, replacing manual logs and spreadsheets with real-time data. Readings are validated via exception handling and plausibility checks to flag anomalies (e.g., sudden spikes) before technicians leave the site.
What is the difference between a 'Counting Meter' and a 'Characteristic Meter'?
A Counting Meter (e.g., production order counter, air compressor cycles) rolls up as items pass through it; a Characteristic Meter (e.g., temperature, pressure) looks for a specific response value rather than a cumulative count.
How does the CMMS calculate the next PM trigger date?
It uses the confirmed post-PM reading as the new baseline; the next trigger is calculated from this value, not the previous date, ensuring the interval reflects actual usage.
What is a 'Meter-reading slope' in reliability analytics?
It is a linear regression on recent meter readings; if a runtime-hour meter crosses 90% of its service interval, the system sharply bumps the asset's risk score.
How are manual meter readings integrated with SCADA systems?
Automatic meter reading (AMR) or Advanced Metering Infrastructure (AMI) reads values directly into a SCADA system, which then interfaces with the CMMS to pass data automatically, eliminating manual transcription errors.
