Compressed Air & Nitrogen Meters
Compressed air is one of the most expensive utilities in any manufacturing facility — and studies consistently show that 25–30% of compressed air is wasted through leaks, pressure drops, and inefficient controls. Monitoring compressed air flow at key points reveals exactly where waste occurs and quantifies the ROI of fixing it.
Emergent Metering offers insertion and inline compressed air flow meters from VP Instruments and Sage Metering, using thermal mass and vortex measurement technologies. These meters measure flow in standard cubic feet per minute (SCFM), normalizing readings for pressure and temperature variations that make simple pressure gauges unreliable.
Common deployment points include compressor discharge, zone headers, production line drops, and individual machine feeds. By comparing supply-side generation with demand-side consumption, facilities can identify leak loads (especially during non-production hours), right-size compressor staging, and verify the impact of leak repair programs. Modbus and analog outputs enable integration with energy dashboards for continuous monitoring and alerting.

Frequently Asked Questions
- Why should I meter compressed air?
- Compressed air is one of the most expensive utilities in manufacturing — typically 25–30% of a plant's electricity cost. Metering identifies leaks, quantifies waste, and enables cost allocation across departments or production lines.
- What technologies are available for compressed air flow measurement?
- The two main technologies are insertion thermal mass flow meters and inline vortex meters. Thermal mass meters are preferred for most compressed air applications because they measure mass flow directly without pressure or temperature compensation.
- Can I install a compressed air meter without shutting down the line?
- Yes. Insertion-style thermal mass meters like the VP Instruments VPFlowScope can be hot-tapped into pressurized lines, allowing installation without shutting down the compressed air system.
