Meters

What is a Meter?

A meter captures a measurable property of an asset over time. An asset can have multiple meters, each tracking a different measurement. For example, a chiller might have meters for:

• Supply water temperature (°F)

• Return water temperature (°F)

• Refrigerant pressure (PSI)

• Energy consumption (kWh)

• Runtime hours (hrs)

Meter Configuration

Each meter is defined with the following fields:

• Meter ID - Unique identifier for the meter

• Name - Descriptive name (e.g., "Supply Water Temperature")

• Unit of Measurement - Text field for the unit (PSI, °F, kWh, RPM, GPM, etc.)

• Low Limit - The lower acceptable threshold for readings

• High Limit - The upper acceptable threshold for readings

• Target Value - The ideal operating value

• Current Reading - The most recent reading value

• Reading Type - How readings are captured (manual, automatic, etc.)

• Status - Current meter status

Reading History & Time-Series Charts

Every reading captured — including low limit, high limit, target value, and current reading — is stored historically. This historical data is plotted as a time-series chart in the Meters tab of the Insights Panel.

The chart enables teams to:

• Visualize trends over time (is temperature creeping up?)

• Identify patterns (seasonal variations, load-dependent changes)

• Spot anomalies (sudden spikes or drops)

• Validate that readings stay within acceptable ranges

• Predict when maintenance will be needed (condition-based maintenance)

Use Cases

• Temperature Monitoring - Track supply/return temperatures for HVAC systems

• Pressure Tracking - Monitor refrigerant pressure, water pressure, air pressure

• Energy Metering - Track power consumption (kWh) for efficiency analysis

• Runtime Hours - Monitor equipment runtime to trigger time-based maintenance

• Flow Rates - Track water or air flow rates (GPM, CFM)
