| Function | |
| - Evaluation of input signals from volume measuring devices, such as woltman, vane, | |
| turbine wheel, vortex, ultrasonic and magnetic-inductive meters, as well as from coriolis | |
| and thermal mass measuring devices. | |
| - Calculating and registering flow rate, capacity, volume, standard volume, mass and | |
| energy. Display of the measured, calculated and cumulative values, as well as certain | |
| auxiliary variables. | |
| - Comprehensive pay scale functions as due date and data logger mode | |
| (any tarif model possible) | |
| - User protection through keyword management | |
| Applications | |
| - Industrial energy measuring | |
| - Building heating and climatisation | |
|
- Meter for costidy transfer for
district heating and local heating (district heat supply, industry, power plants, power distribution) |
|
| - System control in energy systems | |
| - Heat- and cold production im mittle and upper range of performance | |
| - For higher standards on the measurement accuracy and measurement stability | |
| Standard fluids | |
