Control system for small hydropower system
The customer operates his own small hydroelectric power station. His own pond serves as a water source. From there, the water is led to a lower-lying turbine. The electrical energy generated by the turbine is fed into the local power grid. Tailored to the customer's requirements, a control concept was developed which guarantees a cost-effective and simple operation of the hydroelectric power plant. The water level of the pond is monitored by means of float switches via an IoTPilot. The IoTPilot supplies itself with energy around the clock via a solar cell and an integrated battery. The current water level is continuously transmitted to the IoTGateway. One kilometre away from the pond, the gateway automatically controls the operation of the turbine.
Controls for irrigating sports facilities
Large, efficient irrigation systems which can irrigate different sectors at different pressures require the corresponding controls. From the simple DOL or star-delta controls to the regulated frequency converter controls with touch display we can offer everything from a single source. Meier Elektronik AG is a specialist in designing and constructing such irrigation controls. On request we can fit the systems with wireless remote controls, a data modem or telephone controls so you can operate and monitor the pump remotely or the pumps of reservoirs can carry out commands. With our SmartPilot operation via the SmartPhone (iPhone and android) it is possible to give you maximum flexibility in operating and monitoring your system. We can implement client-specific solutions rapidly, efficiently and cost-effectively and look forward to the challenge.
Software development for various solar plants
We have been able to apply on various occasions our extensive knowledge of software development for production facilities in solar plants. Particularly in the sector of thin-film solar cell plants we have many years of experience and specific know-how in chained production lines. We are also experienced in creating MES (Manufacturing Execution System) connections and can communicate with integrators on the same level. We know the requirements of cycle times which are as short as possible and integrated servodrives in NC or CNC controls and programm these with and without visualisation.
Wireless remote control of an intelligent car barrier
Our client was looking for a solution for safe and efficient testing of car tyres on a closed test track. To ensure that hikers or pedestrians could not interrupt the tests the test track was cordoned off with a barrier. On account of the high test speeds the barrier had to be able to be opened quickly by wireless in difficult terrain. With the help of our MultiPilot wireless remote controls fitted with a front panel mount and rechargeable battery, total automation of the barrier was achieved.
fully automatic pyrolysis system
Our customer is doing pioneering work in this project. The operation of a biogas plant generates large amounts of high-temperature waste heat. Often this heat remains unused because no suitable use can be found nearby. This was also the case with our customer's biogas plant in the past. But now he has developed a plant that uses the waste heat directly to produce valuable raw materials from wood on site. Temperatures between 300-800°C force a thermo-chemical splitting of the organic compounds in the furnace - the so-called pyrolysis. In this way, high-quality coal and other by-products can be obtained from the wood raw material. Meier IoT provided technical support for the entire plant development. An automation system tailored to the plant was developed. All plant values are recorded and visualised on a customer-suitable data portal, and the customer can access all plant values from all devices (laptop, smartphone, tablet). In addition, the data portal has a fault and alarm manager, which informs the customer via SMS or email as soon as something is wrong with the system.
Level control for an existing water supply
The existing water supply system has sufficient water for own consumption and can therefore supply part of it to the neighbouring community. To ensure that the own demand is always covered, a special level control between the reservoir and the gate valve shaft is needed. The level is transmitted to the gate valve by radio and if the level falls below a certain threshold, the gate valve closes and no longer supplies water to the neighbouring community. Meier Elektronik AG supplied the entire level control system including radio and installation.
