The test bench is especially designed for the calibration of domestic gas meters (diaphragm gas meters, ultrasonic gas meters, thermoelectric gas meters). The test bench has a modular design - it is possible to combine 1x6 to 4x6 clamping points for gas meters. The modular design allows 1 to 12 gas meters to be tested simultaneously. In parallel, up to twelve test specimens can be adapted, run in and leak tested. The leak tests are carried out automatically.
The gas meters are tested at three or more measuring points. A magazine made of three sonic nozzles is used as a flow sensor. The nozzle magazine can be exchanged with just a few hand movements so that up to five different gas meter types can be calibrated on one test bench.
Optionally, a nozzle drum with nine combinable nozzles can be used. This al- lows the generation of up to 512 different flow points.
This means that all five gas meter types G1.6..G10 can be tested without nozzle change.

Benefits:

- High long-term stability through the use of sonic nozzles
- Highest accuracy by the use of sonic nozzles
- Optimum capacity utilization - short process times
- Integrated plausibility check of the meter signal
- Automated counter monitoring
- Fast and stable adjusting of the volume flow
- Modular system for 1 to 24 units
- Long-term stable measuring elements - low recalibration effort
