It happens out of sight
Trucks, cranes, tankers and stations operate far from the office. Nobody sees what happens until someone reports it.
Industrial IoT engineering bureau
Know what happens across your fleetsmachinessites
before it costs you money.
Melqart Systems designs and delivers IoT solutions for the problem you need solved: quality on every concrete load, cranes diagnosed remotely, safer feed tankers, theft and fraud flagged at petrol stations. Field-proven building blocks get you to a working pilot in 6 weeks.
Sound familiar?
You find out after it has cost you.
A wasted service trip, a disputed concrete load, fuel that disappears between deliveries. Without data from the field, problems surface when the bill arrives. We put the right signals in front of the right people while there is still time to act.
Someone goes to look
A technician or an inspector travels to find out what went wrong, often without the right part or the right information.
The cost is already paid
A second trip, a rejected load, a stock loss. The money is gone before anyone knows the cause.
What changes
What changes when your assets report in.
Machine data is only worth collecting if it changes decisions on the ground. These are the decisions it should change.
Fewer wasted trips
You send someone when the data says the drive is worth it, not to find out on site what broke.
Quality you can prove
Drum rotation, drum pressure and location recorded on every concrete load, ready before a dispute starts.
Safer operations
Live subsystem status and a complete data log, so unsafe conditions show up on the road, not after an incident.
Losses caught early
Theft and fraud flagged as they happen, not weeks later at the reconciliation.
What we connect
From field signals to business decisions.
Start with rugged gateways, then connect the signals to the software your teams already use.
Industrial 5G routers & IoT gateways
Rugged hardware for PLCs, meters, sensors and remote assets, with Modbus, OPC-UA and MQTT integration.
Explore
Maintenance & asset software integration
Feed CMMS, EAM and ERP systems with runtime, alarms, condition data and work-order-ready events.
Explore
Condition & process monitoring
Turn vibration, level, flow, temperature and runtime signals into alarms, dashboards and maintenance context.
Explore
Remote access & OT security
Give operations controlled remote diagnostics, updates and gateway access on infrastructure you control.
Explore
Concrete truck tracking
Drum rotation, hydraulic pressure, GPS and delivery events from every mixer truck, on a gateway you own.
Explore
Building management
Connect BMS, HVAC, metering and controls data to monitoring and reporting workflows.
Explore
M2M connectivity
Industrial routers and gateways for remote device fleets, with connectivity options you choose and control.
Explore
Energy management
Bring metering, load and site energy data into the systems your teams already use.

How we deliver: fixed scope, fast results, no hidden costs.
Whether you run a fleet, operate fixed sites or build machines as an OEM, every engagement is scoped to a measurable result, and you keep full control of what we build.
Strategic consulting & discovery.
Should you build this, and if so, what's the clear path to ROI?
We analyze your existing telemetry stack, run feasibility studies, and deliver a comprehensive architecture design document. The artifact is yours to keep, whether you build it with us or not.
End-to-end implementation.
Built on field-proven Owasys gateways.
A fully integrated system: ruggedized hardware, custom embedded software, secure cloud brokers, and unified operational views. Every deployment uses preconfigured, git-versioned Linux images with secure OTA management. You own the gateway and every line of code that runs on it.
Managed operations.
Managed operations, or a full handover to your team.
Optional managed operations, with quarterly checkpoints so you can transition operations fully in-house at any time, with no clawback and no licensing surprises.
Why engage with us
Added value baked into every engagement.
Four commitments built into every engagement, so you see results fast and stay in control.
A working pilot in 6 weeks.
Proven building blocks, adapted to your problem.
We have worked with concrete fleets, crane operators, tanker manufacturers and petrol stations. Your project starts from field-tested hardware and software, not a blank page.
Customer-owned IP.
Source code, schematics, and machine data belong to you.
Every engagement ends with git-versioned source code, hardware schematics, production access credentials, runbooks, and the accumulated machine data. The system runs without us.
Customer support with fast response.
Engineering support from the team that built your system.
Support from the engineers who built your system, not a tier-1 call center. Fast response on incidents and direct access to the team that knows your stack.
Cost transparency.
Fixed-scope work, written budgets, no licensing surprises.
Every engagement starts with a written budget and a fixed scope. There is no per-asset licensing, no clawback, and no per-feature upsell: the price you agree to is the price you pay.
Case studies
Proven in the field
Real engagements with fleets and OEMs, each built around a specific operating problem.
Concrete fleetCase 01 · Mobile fleet
Concrete fleet: drum rotation, slump proxy, work events
GPS, drum rotation and drum pressure on every mixer truck to monitor delivery quality, with data stored on the customer's infrastructure.

Hardware & ecosystemField-proven hardware.
Field-proven hardware.
Industry-standard software.
Owasys is our authorized hardware partner, supplying production-grade OWA gateways engineered for harsh industrial environments.
The software runs on proven, widely used components: Linux, Yocto, Mosquitto, Kafka, TimescaleDB, Grafana.
Nothing your team cannot maintain or replace.
How it works
Three steps from idea to running system.
Bounded engagements, written deliverables, and a working pilot in 6 weeks.
Discovery
We work with your team to audit the existing stack and identify integration risks. The outcome is a feasibility report and a written architecture design, yours to keep, whether or not we build the system.
Planning
We translate the design into a delivery plan: bill of materials, work packages, milestones and budget. Quarterly checkpoints, transparent budget, no surprises.
Execution
We build, integrate, and roll out ruggedized gateways, custom embedded software, secure brokers, and operational views. At handover, you keep the source, the schematics, the credentials, and the data.
Questions we hear often.
01What does Melqart Systems do?
We are an engineering bureau that designs and delivers industrial IoT solutions. We connect machines, vehicles and sites to the systems your teams already use, so they see faults, quality issues and losses before they cost money. Past projects include concrete truck quality monitoring, crane remote diagnosis, feed tanker safety monitoring and petrol station anti-fraud.
02Where is Melqart Systems based?
Melqart Systems is an engineering company based in Luxembourg. We work in English, French and German.
03Which machines do you work with?
Mobile machines and vehicles such as concrete mixer trucks, cranes and bulk tanker trailers, as well as fixed plant equipment and sites.
04How is this different from buying a gateway?
A gateway is one part of the job. We start from the operating problem, for example diagnosing before travel, proving a delivery or documenting a cleaning cycle. Then we choose the hardware (usually Owasys industrial gateways), write the software that runs on it and connect it to your systems.
05Who owns the software and the data?
You do. Machine data goes to infrastructure you control, and the source code we write for your project is handed over to you. There is no per-asset licensing.
06How does a project start?
With a short discovery: a few assets, the signals that matter and where the data has to end up. You get a written scope and budget, and a working pilot follows within 6 weeks.
