Depth of manufacturing
At many manufacturers, “Swiss Made” stops at the housing and the company logo. With us it starts at the circuit and extends to the assembled board: PCB assembly takes place in Switzerland. That costs more than sourcing a circuit board abroad – and pays off where delivery reliability, revisions and traceability count.
Circuit design, firmware and the web interface are created in house in Baar. Whoever is responsible for a function sits in the same building as the person who supports it.
The boards are assembled in Switzerland. Short distances to production mean that component changes, revisions and small series are feasible in weeks rather than quarters.
Assembly, functional testing and marking take place in Switzerland – every device with its own serial number.
Project support from planning through integration to commissioning – especially where different meters, protocols and software systems meet.
How an EMU power meter is made: nine stations from the bare circuit board to the packed device.
Station 1 of 9
The bare circuit board enters the SMT line. Components are placed precisely, and their date codes and batch numbers are captured and assigned to the production record.
Every component is documented and traceable.
Station 2 of 9
A camera checks placement, component orientation and visible solder joints. The result is documented.
Automated visual inspection for reproducible manufacturing quality.
Station 3 of 9
Test probes are lowered onto the board and electrical test points are measured one after another. Only a board that passes moves on.
Electrical faults are detected early.
Station 4 of 9
Housing, circuit board, display and front are assembled into the meter. The board data stays linked to the device.
Tested electronics become a complete measuring device.
Station 5 of 9
The device serial number and the circuit board serial number are captured and linked digitally. The digital twin is created: batches, date codes and all test results now belong to exactly this device.
Complete traceability from the component to the finished power meter.
Station 6 of 9
Initial test, check of the communication interfaces, optical LCD inspection by camera and automated key test.
Every device is fully tested for its functions.
Station 7 of 9
Under defined test conditions the device is calibrated against a reference measuring system. The calibration values are assigned to the digital twin.
Precise calibration as the basis of reliable measurement.
Station 8 of 9
After calibration, measuring accuracy is tested separately and compared with the permissible limits. Only then is the device released.
Every power meter has to pass its accuracy test.
Station 9 of 9
All tests are checked. The laser marking according to MID requirements is applied, and the device is labelled and packed. Test results are kept for at least 10 years as required by MID.
Tested, documented and ready for use.

Small teams and short paths: decisions are made in Baar, not in lengthy approval rounds.
Short delivery times, because the devices are here rather than on their way.
System solutions from measurement to billing, with trained system integrators, scalable from a single-family house to an industrial site.
Group and locations
EMU Electronic builds electricity and power meters, data loggers and energy management software. The sister company Helvatron manufactures heat and water meters. The other companies in the group bring both product worlds into their markets – with distribution and pre- and after-sales on site.

How we work
Most projects founder not on the hardware but on a metering concept that does not support the billing later on. That is why a project with us starts with a conversation and – where it is worthwhile – a workshop on site.
Whether it is a new build, a refurbishment or a meter estate that has grown over the years and should finally deliver data – we will tell you openly what our devices can do and what they cannot.
