Leak detection

Compressed air leak detectors and acoustic camera

On average, around a quarter of compressed air is lost through leaks. Ultrasonic detectors and the LeakCam 600 camera find even the smallest leaks during production, measure their size in l/min and show the cost in € per year.

Why look for leaks

Leaks are the most diligent consumer – 365 days a year

Unlike a water leak, a compressed air leak is invisible. Even at weekends and during downtime, compressors run just to replace the air that escapes. In older networks, leaks account for 25–35 % of consumption.

Example from the CS Instruments catalogue: a company with 150 kW of compressors, 6,000 operating hours and €0.24/kWh pays €216,000 for electricity per year – 25 % leakage means a loss of €54,000. Joints, quick couplings, hoses and welds leak most often.

  • Detection during productionUltrasound around 40 kHz – ambient noise is filtered out, so production does not have to stop.
  • Size and costThe leak in l/min and the cost in € per year are shown directly on the device.
  • Laser distanceAutomatic distance measurement to the leak for an accurate size calculation.
  • PaperlessPhoto, location, action and spare part on the spot – then an ISO 50001 report.

Loss calculator

How much do leaks cost you?

Choose the size and number of leaks and the network pressure. The calculator uses the leakage cost table from the CS Instruments catalogue.

Leakage cost per year

14,440 €

Air lost per year760,000 Nm³
Total leakage1,446 l/min

The calculation is based on the leakage cost table in the CS Instruments catalogue (1.9 ct/Nm³, 24 h × 365 days) and is an estimate only. The LD 500 or LeakCam 600 measures the exact size of each leak.

1

Find

Inspect the network during operation with a detector or camera and tag the leaks.

2

Document

Save a photo, size in l/min, cost, location and required spare part on the spot.

3

Repair and verify

Prioritise repairs by cost. Use a flow meter to verify how much consumption has dropped.

How to choose

How to choose a leak detector

  1. Network size

    For occasional checks the LD 450 is enough, for regular inspections the LD 500 with cost calculation.

  2. Inspection speed

    The LeakCam 600 acoustic camera shows several leaks at once and speeds up inspection of large halls.

  3. Documentation

    For ISO 50001 reports choose a device with a camera and the CS Leak Reporter software.

  4. Other gases

    The detectors find leaks in compressed air, gas and vacuum systems – including ammonia and CO₂ refrigeration systems.

FAQ

Leak detection questions

How does an ultrasonic leak detector work?

Gas escaping through a small opening creates ultrasound around 40 kHz, inaudible to humans. The detector picks it up, converts it into an audible signal in the headphones and estimates the leak size from the intensity and distance.

Do we have to stop production during detection?

No. The detectors filter out ambient noise, so leaks are found during normal operation.

How much does one leak cost?

According to the CS Instruments table (1.9 ct/Nm³, 24 h × 365 days), a 1 mm leak at 6 bar costs about €632 per year, a 3 mm leak already about €5,685.

What is the difference between the LD 500 and the LeakCam 600?

The LD 500 has a directional microphone and a camera for documentation – you find leaks one by one. The LeakCam 600 has 64 MEMS microphones and shows several leaks on screen at once, so it is faster for inspecting large areas.

Do I get a report for ISO 50001?

Yes. With the CS Leak Reporter software (on a PC or in the cloud) you create a report with the number of leaks, total leakage in l/min, costs and CO₂ per year.
