MULTI-FLUID AUDIT AND SUB-METERING PLAN

Our teams analyse your fluid networks and identify strategic measurement points: site inlets, workshop distribution lines, critical equipment. A sub-metering plan is established based on your network diagrams or following a technical visit to your site.

2

CONNECTION TO EXISTING METERS OR INSTALLATION OF NEW METERS

Technicians work on site to connect the hub to your existing fluid meters. The operation takes place without interrupting production, in just a few hours.

Data available immediately

As soon as the installation is complete, your fluid consumption is visible in your energy management tool and the history starts feeding in real time.

Monitor your fluid consumption and achieve significant savings

Consumption data for fluids required in industrial production is rarely centralised. The overall bill amount is known, but rarely the consumption at the level of a production line or a specific piece of equipment.

Detect leaks and waste

With the Lynx+, consumption data for all your fluids (water, gas, compressed air, fuel oil...) and your processes flows back in real time to your energy management software. This way, you can quickly identify anomalies and act before deviations impact your costs.

IDENTIFY WHERE AND HOW ENERGY IS CONSUMED

Implementing a fluid sub-metering system allows you to precisely identify consumption by zone, by production line or by equipment. This is essential data for understanding your production costs in detail and implementing improvement actions.

Act without heavy investment

Most fluid savings opportunities are quickly accessible. Often, the fixes relate to individual behaviour or the organisation of your plant: reviewing operating schedules, maintaining and repairing equipment, or optimising machine settings, for example. By measuring your fluid expenditure, you can directly observe the impact of your actions.

The Lynx+ is your ally for measuring and reducing your energy expenditure and identifying leaks.

Petit Bateau saves €435,000 per year on gas and electricity consumption

Petit Bateau instrumented its industrial site with water, gas and electricity sub-metersPetit Bateau saves €435,000 per year on gas and electricity consumption

Petit Bateau, one of our longest-standing clients in the textile industry, deployed a comprehensive measurement system for its water, gas and electricity consumption at its historic Saint-Joseph site.

Thanks to the data collected, the teams became aware of significant waste, particularly when the factory was not in production.

They first revised their production shutdown procedures to minimise consumption in the evenings and at weekends.

A real-time alert system was then put in place to detect anomalies such as leaks or valves left open by mistake.

All of these actions enabled this factory to save an average of €435,000 per year on gas and electricity, measured and verified in line with the IPMVP protocol.


Simplified installation

  • Installed without connection to your local IT network (the data transmission connection is independent of your network)
  • The Lynx+ is agnostic and adapts to all your existing fluid meters

Data access

The consumption measured by the Lynx+ is accessible via the Wattseeker energy management software, through an open API or on a Modbus TCP server. Data access is available regardless of your network, your industrial supervision or on the Wattseeker platform.


Maintenance

The proper functioning of the hubs is monitored remotely by our teams.

Software updates are included in the contract.

Technical support is available live during opening hours.

Your questions about our fluid sub-metering solutions

The Lynx+ integrates a concentrator (gateway) that enables data collection from fluid meters installed on site. The connection is wireless or wired depending on the specific characteristics of the installations. 

The Qualisteo team can handle the installation of fluid meters (water, gas, compressed air, fuel, process). To do this, technicians create a dedicated metering plan and specify the meters that need to be installed.

Once the fluid meters are validated, the data will be available either on the Wattseeker platform or on another platform.

Qualisteo's technologies are specifically designed to manage large industrial sites with complex networks. Each Lynx+ sub-meter can simultaneously handle several dozen sub-metering points. The most complex projects managed by Qualisteo include several hundred sub-metering points.
