Introduction:
The Riveja's customer is one of the world largest brewing companies. On beer brewing plant located in Eastern Europe installed Delphin LogMessage data loggers in order to install an effective monitoring system and to find ways to reduce energy consumption.
Application / Problem:
The customer is operating a brewing plant and decided to install a Delphin LogMessage monitoring system to monitor energy consumption of CO2 for beer carbonizing process, steam flows, sewage flows and electrical energy consumption.
Proposal / Solution / Hardware:
For this installation a LogMesage 200 with 10 universal analog inputs and 11 digital and counter inputs was installed in a control cabinet of the production plant.
The analog inputs are interfaced with different steam, CO2 and sewage flow meters via 4-20 mA signals. The interface o fteh 2 ware flow meters from Siemens MAG 8000 was realised through the Modbus RTU interface. The Modbus registers where easily created on the 2 serial COM ports of LogMessage device. The customer is also using the internal calculation channels to calculate indicators from the live data. For example an integrator channel is used to totalize the energy and CO2 consumption of the brewing process.The functional design is shown below.
The process supervisor has a PS with a ProfiSignal Klicks software application to monitor live reading of the process. The mimic interface was easily developed with the ProfiSignal software and is shown below.

Summary of Benefits:
The advantages of the LogMessage installation are the following:
Ø The LogMessage with universal analog and digital inputs can easily record all analog 4-20 mA signals and also the digital inputs from the energy meter with pulse output.
Ø The LogMessage devices support many serial interface and the MAG 8000 flow meters could be easily interfaced via Modbus RTU protocol
Ø The internal calculation channels for alarm monitoring and totalize give the operator live readings of key indicators
Ø The internal logger memory with 1 GB capacity is storing the process data for backup functions. The live data is also archived in the DataServic Configurator online data base.
Ø The ProfiSignal Klicks software also enable the operator to generate different reports and statistics of the process
