VALVESENSE ValveSense LL-VS1 AI Ultrasonic Valve Internal Leak Diagnostic Device

Are You Inspecting Your Valves?

It is said that 5-10% of valves in a factory are leaking. Internal valve leaks are invisible, and conventionally required removing valves for testing on a bench with a 2-person team over several days. Line shutdowns were also unavoidable during this process.

The VALVESENSE LL-VS1 is an AI ultrasonic valve internal leak diagnostic device developed by Senseven of Austria. Combining ultrasonic (AE: Acoustic Emission) technology with AI algorithms, it diagnoses internal leaks on-site in just 1 minute without removing the valve. The smartphone app guides you step by step, requiring absolutely no specialized knowledge.

As the world's first valve leak diagnostic solution combining AE + AI + mobile technology, its open architecture enables seamless integration with existing asset management systems. Adopted by leading global companies including Shell, Exolum, and Bayer.

4 Key Features

Easy Operation

Works in conjunction with a smartphone app - simply follow the on-screen guidance for anyone to perform diagnostics. No training required, ready for field use from day one.

Rapid Inspection

Detects potential defects in just seconds. Diagnosis completes in approximately 1 minute per valve, a dramatic reduction from the conventional test bench method (2 people, several days).

Automation

AI algorithms automatically analyze ultrasonic data to determine the presence of leaks and estimated flow rates. Delivers objective, reproducible diagnostics without relying on human experience or intuition.

Automatic Report Generation

Inspection results are automatically generated as reports with leak determination and recommended actions. Cloud-based data management enables trend tracking over time, and sharing results is easy.

Comparison with Conventional Methods

Conventional test bench methods required removing the valve and inspecting with a 2-person team over several days. With VALVESENSE, diagnosis is completed on-site by 1 person in 1 minute.

TrapSense Mode

Steam trap diagnosis - TrapSense mode concept diagram

VALVESENSE is equipped with TrapSense mode, a dedicated steam trap diagnosis function. It simultaneously measures ultrasonic (AE) and temperature to automatically diagnose steam trap conditions in 5 levels.

Energy losses from steam leaks can reach tens of millions of yen annually, making regular trap diagnosis directly linked to energy savings and cost reduction. With one VALVESENSE unit, you can diagnose both valves and steam traps, contributing to streamlined equipment management.

3-Step Measurement Method

VALVESENSE measurement principle - leak detection via AE ultrasonic

Measurement principle: Leak detection via AE ultrasonic

VALVESENSE sensor placement - measurement points set at 3x pipe diameter intervals

Example of sensor placement positions

Step 1: Confirm Pressure Differential

Confirm that a pressure differential of 0.1-0.3 MPa exists between the upstream and downstream sides of the target valve. Without a pressure differential, ultrasonic signals from leaks will not be generated, so this must be verified before measurement.

Step 2: Ultrasonic Measurement with AE Sensor

Press the AE sensor against the pipe surface to measure ultrasonics. Measurement points are set at intervals of 3 times the pipe diameter. Simply place the sensor at the designated locations following the app's on-screen guidance.

Step 3: Diagnostic Results

The AI algorithm automatically analyzes the data and instantly displays leak presence and estimated flow rate on screen. Reports with leak determination and recommended actions are automatically generated and saved to the cloud.

Case Studies

Case study: VALVESENSE deployed at a paper mill

Paper Mill

VALVESENSE was deployed for internal leak inspection of large valves. Previously, valves had to be removed and tested on a bench, requiring significant time and personnel. With VALVESENSE, inspection of large valves is completed in just 1 minute. Valve removal is no longer necessary, minimizing downtime and successfully achieving a significant reduction in production losses.

Case study: Steam trap diagnosis at a thermal power plant

Thermal Power Plant

TrapSense mode was utilized for periodic steam trap diagnosis. The 5-level diagnosis using simultaneous ultrasonic and temperature measurement objectively evaluated steam leak conditions. As a result, steam losses from steam trap leakage worth approximately 19.2 million yen annually were discovered, significantly contributing to repair planning prioritization and cost reduction.

Global Adoption

Leading global companies have adopted VALVESENSE to achieve preventive maintenance and cost reduction for their equipment.

Frequently Asked Questions

Does the ValveSense LL-VS1 require specialized knowledge for diagnosis?

No specialized knowledge is required. The smartphone app guides you step by step, so anyone can immediately perform valve internal leak diagnosis without training. The AI algorithm automatically determines the presence or absence of leaks.

Can it diagnose valves wrapped in insulation?

Yes, it can diagnose valves even when wrapped in insulation. By making a small hole in the insulation and using the included high-temperature pipe attachment (wave guide), measurement is possible.

Can it also diagnose steam traps?

Yes, it is equipped with TrapSense mode, which diagnoses steam trap conditions in 5 levels through ultrasonic and temperature measurements. This is useful for understanding energy losses caused by steam leaks.

Can one unit inspect all valves in an entire factory?

Yes. VALVESENSE is a portable device, not a fixed installation, so one unit can be used for patrol inspection of all valves throughout a factory. One-person operation is possible, dramatically reducing inspection labor compared to the conventional test bench method (2 people, several days).

Can it be used in explosion-proof areas?

An EX version with IECEx certification is available in an explosion-proof specification, making it suitable for use in hazardous areas.
