Innovative Index Features
This section highlights advanced features related to the index of the gas meters, focusing on security and accuracy.
Innovative Index with Innovative Protection Against Fraud:
- New Generation Solution for Seal: Stamp from inside.
- Index Blockade: Option to make the index disassemblable or non-disassemblable.
- Blockade of Counting Reverse Flow: Prevents reverse flow from being counted.
- Place for Applying Traditional Seal (Optional).
Mechanical Temperature Compensation
Gas meters UG G1.6 up to UG G4 can be equipped with mechanical temperature compensation (bimetal).
Gas volume changes with temperature due to thermal expansion. This affects the measuring accuracy relative to energy content. For instance, heating gas increases its volume, leading to a higher indicated consumption, while cooling decreases it. This is particularly relevant for meters installed outdoors. Temperature compensation mechanisms adjust the cyclic volume to counteract expansion or contraction, ensuring the gas meter converts measured volume to its value at a fiducial temperature, irrespective of the actual measuring temperature.
Curves of Typical Error and Pressure Loss
Detailed performance curves illustrating typical error and pressure loss characteristics for various gas meter models under different conditions.
