Ambient Noise Dampening: Excellent – Wood’s structure absorbs surrounding noise very effectively, allowing rapid, accurate focus on leak sounds.

Low-Frequency Sound Transmission: Best – Medium density picks up and transmits low-frequency leaks clearly without resonating or reflecting back.

Sound Tone: Warm & Smooth – Comfortable for prolonged listening; helps distinguish low frequencies clearly.

Weight & Portability: Lightest – Very lightweight and easy to carry, reducing user fatigue; ideal for long field sessions.

Environmental Durability: Very Good – When stabilized or properly coated, it resists moisture, termites, and mold for extended use.

Ergonomics (User Feel): User-Friendly – Warm to the touch, non-slip grip, and minimal vibration transfer even with loud sounds.

The MV145 can be powered by lithium or alkaline batteries  and can be easily replaced, without interrupting the measurement.
Batteries have an estimated life of 15 years or more based on measurement conditions.

Optionally the MV145, can be powered from the mains, c.a. or c.c. or from a solar panel via the DC connection; in this case the batteries have a backup function, avoiding data loss in the event of a power failure.

The MV145 coupled to the MS2500 flow sensor (up to DN1000) complies with the European directive 2014/32/EU MID, Annex III MI-001.

The converter has an internal logger capable of storing flow and pressure data with a recording capacity of 4 GByte, which guarantees years of recording.
The instrument is equipped with complete diagnostics thanks to the BIV (built-in verifier) which constantly monitors various sensor parameters, anticipating possible problems.

Allows programming via keyboard and display or with mini USB cable connected to the PC via MCP software.

The battery converter for flow meters MV145, flow meters, energy meters, ultrasonic flowmeters, and industrial automation systems have been ISOIL Industria‘s passion and continuous research since 1958, and for any information or advice please do not hesitate to contact our specialists.

The Eureka5 offers in case battery charging, either from the mains or a vehicle, which means it’s always ready when you are. Ruggedised and portable, it is designed for on-site use in challenging environments. The Eureka5 provides high performance leak location even on plastic pipe.

The Eureka5 software is intuitive in design and can be upgraded as new features are developed, future proofing your investment. It also has the ability to be upgraded remotely via Wi-Fi, 4G or 5G.  The touch screen ensures easy operation involving the minimum actions to achieve results.

Existing customer tablets can also be used with the Eureka5 and with Ovarro’s expanding portfolio of leak detection devices. This reduces capex costs, as existing tablets can be utilised. For example, sometimes pipe fittings are not easily accessible, or excessive noise interference exists during the day, in these situations, the Enigma correlating loggers can be programmed from the same tablet and deployed. Off-line correlation can be carried out at any time including overnight. When the correlation is complete the results are analysed on PrimeWeb and the leak location is marked onsite.

Using default velocity values to detect leaks noises can lead to potential errors in the leak position. Instead, the Eureka5’s velocity correction function analyses a peak produced from induced noise at a known location to measure the velocity. This can be used at a touch of a button to give a more accurate leak location result.

The Eureka5 incorporates spectrum analysis enabling the user to see which frequencies are being heard at each sensor. A coherence function aids users in their filter section improving the ratio of leak noise to background noise sharpening the correlation. Default filters are auto selected based on pipe material.

The Enigma3hyQ correlating loggers transmit daily leak noise data to our server via the 3G or GPRS communication networks. Correlation is performed from many loggers to
accurately locate leak positions. The user has the opportunity to listen to the recorded noise thus helping to confirm correlation results are due to leak noise. To enable accurate
correlations a daily logger time synchronisation is carried out by a new technology

Network flow, pressure and leak location data

PrimeWeb provides a database and on-line viewing facility for network flow, pressure and leak alarms from XiLog+ data loggers, Phocus3/3m noise loggers and Enigma3m correlating noise loggers. It is accessible on any device with internet access. Logger positions can be shown on Google Maps* and coded to show leak alarms.
Historical data is also available. Indication of leak positions on Google Maps* together with ‘street view’visualisation of the leak position aids management for leakage teams.

System features

• Aggregated correlations for difficult leaks
• Auto-velocity determination for accurate leak location
• Small size for fitting into underground chambers – no
above ground installation required
• Logger powered for 5 years (dependent upon 3G/GPRS
signal conditions)
• Logger GPS location saved
• Logger submersible to IP68

Imagine two identical swimmers crossing a river on the same diagonal line, one with the flow and the other against the flow. The swimmer moving with the flow needs much less time to reach the opposite bank. Ultrasonic waves behave exactly the same way. The sound wave that flows in the direction of the stream moves faster than the one that flows against the stream. The transit times TAB (Transit time of ultrasonic waves from sensor A to sensor B) and TBA (from sensor B to A) are measured continuously. The time difference (TBA – TAB) is directly proportional to the mean flow velocity (Vm) of the liquid. The flow rate is a result of the velocity multiplied by the cross section area of the flow tube size.

Data Transfer
All loggers may be configured to use GPRS or SMS remote communications for periodic reporting. Transmission period can be set from 15 minutes to 24 hours. The state-of-the-art antenna enables XiLog+ to operate from below ground in most locations. In areas of poor GSM/GPRS coverage an external antenna option is available.

Flow
The flow input can log two uni-directional flows or one bi-directional flow. Also, both outputs from combination meters can be logged on one logger input channel. Existing meter index value can be entered at start of logging. Operation with, but not limited to, the following flowmeters:
