Other functions
• Totalizers – two totalizers per flow value (measured or calculated)
• Tracking minimum, maximum and average value of each measured and calculated quantity in the selected time interval

Application
The MPI-C recorders are used in the energy, chemical, pharmaceutical, food, metallurgical industries, manufacturing, laboratories, and wherever measurement values registration are required. They are mainly used for recording eg. temperature, humidity, pressure, flow and flow rates. Example of apllication: monitoring of steam produced in boiler (pressure, temperature, flow rates).
