Laser Bubble Counter – Precision Leak Testing for Valves

The METRUS Laser Bubble Counter is a high-precision system for valve leak testing in accordance with international standards.
It is designed to improve the efficiency, accuracy, and repeatability of leakage testing for safety valves, control valves, and shut-off valves in production and quality assurance.
Measurements are displayed in bubbles per minute or per hour, enabling precise detection of even the smallest leaks. This makes the system an ideal valve leak tester, bubble leak tester, or digital bubble testing device.

Relevant testing standards:
- API 527 (safety valves)
- EN 60534-4 / ANSI FCI 70-2 (control valves)
- EN 12266 (shut-off valves)

 Function and operation
The system is supplied with three precision measuring tubes, allowing easy adjustment of the correct water level.

Operation is managed via an intuitive touchscreen interface. Measurement duration and delay time can be individually configured, ensuring maximum flexibility for different testing scenarios.

 Key benefits
- Precise leak detection (bubbles/min or bubbles/hour)
- Compliance with international testing standards
- Easy and intuitive operation
- Fast and repeatable results
- Universal power supply (100–240 V, 50/60 Hz)

 Integration and applications
The Laser Bubble Counter can be used as a stand-alone test unit or integrated into new or existing test benches.

Typical applications include:
- Valve leak testing in serial production
- Quality control processes
- Test systems for industrial valves
