Start with the decision you need to make
Measure the parameter that changes the process
A measurement system should turn operating conditions into an actionable decision. Define the target, measuring location, alarm limit and required evidence before choosing the instrument.
Quantify consumption and leakage
Measure flow by production area, identify compressed-air losses and establish reliable energy-performance baselines.
Explore flow measurement →Record, alarm and optimise
Connect sensors, data loggers and master control so deviations produce alarms, reports and corrective action.

Match the instrument to the operating question
| Operating question | Measured parameter | Relevant technology | Main design check |
|---|---|---|---|
| Is the air dry enough? | Pressure dew point | Stationary or portable dew point meter | Expected range, pressure and response time |
| Where is compressed air consumed? | Volume or mass flow | Inline or insertion flow meter | Gas, pipe diameter, flow range and inlet run |
| Is residual oil controlled? | Oil vapour / total oil | Continuous oil-content monitor | Target class, sampling and calibration |
| Where is energy being lost? | Leak rate and annual cost | Ultrasonic or acoustic-camera detector | Access, noise environment and reporting |
| Is gas purity on target? | O₂ concentration | Oxygen analyser | Measuring range, sample pressure and gas matrix |
| Which compressors should run? | Station pressure and machine status | Master controller | Compatibility, sequencing and redundancy |
The complete monitoring chain
Turn sensor values into corrective action
Reliable monitoring connects the physical measuring point with signal transmission, recording, alarm management and a defined response.
01Define the target
02Select measuring point
03Install sensor
04Transmit & log data
05Set alarms
06Act & verify
Document reference conditions, calibration status, alarm limits and sensor location so values remain comparable over time.
Measurement architecture
Connect each measurement to an engineering objective
Use continuous monitoring where deviations can damage product or waste energy; use portable audits where periodic evidence and troubleshooting are sufficient.
| Objective | Measurement package | Primary selection data | Result |
|---|---|---|---|
| Verify dryer performance | Dew point sensor + display/logger | Dryer type, PDP range, pressure and alarm | Early detection of moisture breakthrough |
| Allocate compressed-air cost | Departmental flow meters | Pipe sizes, flow range, pressure and interfaces | Consumption by machine or production area |
| Reduce leakage losses | Leak detector + reporting | Plant size, pressure, access and audit frequency | Prioritised repair list and savings estimate |
| Document critical air quality | Dew point + oil + particle monitoring | ISO classes, sampling point and validation plan | Traceable quality evidence |
| Protect gas purity | O₂ analyser + alarm output | Gas, purity range, sample pressure and response | Continuous purity supervision |
| Optimise compressor sequencing | Master controller + flow/pressure data | Machine compatibility, demand and control band | Stable pressure with efficient machine selection |
Final selection must confirm sensor compatibility, reference conditions, interfaces, calibration requirements and the data retention needed by the operator.
Standards & performance
Measure air quality and energy performance separately
ISO 8573-1 describes compressed-air purity classes, while energy management needs consumption, leakage and operating data. A complete plan connects both.
Quality
Define particle, water and oil classes, then measure each parameter at the relevant point of use.
Energy
Measure consumption, pressure and leakage so improvement projects start from a reliable baseline.
Traceability
Record time, location, reference conditions, calibration and alarms so the data remains auditable.
Applications
Measurement for quality-critical and energy-intensive processes
The measurement plan changes with product-contact risk, gas-purity requirements, production continuity and energy-management priorities.
Selection checklist
Send the data needed for a measurement proposal
Instrument selection needs the expected range, operating conditions, installation point and required outputs—not only the parameter name.
- 01Parameter and expected minimum/maximum range
- 02Gas type, operating pressure and temperature
- 03Pipe diameter, connection and available straight run
- 04Stationary monitoring or portable audit
- 05Required accuracy, response time and alarm limits
- 06Display, logger and data-retention requirements
- 07Analogue, pulse, Modbus, Ethernet or other interface
- 08Power supply and control-system integration
- 09Calibration interval and certificate requirement
- 10Installation environment and process approvals
For final selection, BERG should confirm the measuring range, installation method, materials, signal outputs, calibration and any process-specific documentation.
Technical FAQ
Questions before selecting compressed-air measuring technology
Which parameters should be measured in a compressed-air system?
Common parameters include pressure dew point, flow, pressure, temperature, oil content, particles and leakage. The correct combination depends on air-quality risk, energy objectives and the decisions the operator must make.
Where should a compressed-air sensor be installed?
Install it where the value represents the required decision: after treatment for dryer performance, by department for consumption, or at the point of use for process quality. Follow the instrument’s pressure, flow and straight-run requirements.
What is pressure dew point?
Pressure dew point is the temperature at which water vapour would condense at the actual compressed-air pressure. It is the relevant moisture value for verifying dryer and system performance.
How does flow measurement reduce compressed-air cost?
Flow measurement reveals base load, peaks, consumption by production area and changes during non-production periods. These values help identify leaks, allocate costs and verify improvement projects.
How often should measuring instruments be calibrated?
The interval depends on the sensor, process risk, manufacturer guidance and quality-management requirements. Critical measurements should have a documented calibration plan and traceable records.
Which measurement brands does BERG supply and integrate?
BERG supplies and integrates selected compressed air measuring instruments from CS Instruments and BEKO Technologies. For oxygen and nitrogen gas-generation systems, BERG also supplies Ntron oxygen sensors and analyzers. The final brand and model depend on the parameter, measuring range, process conditions, interfaces and required documentation.
