Diaphragm gas meter with temperature and pressure corrector (GAS SOUZAN)
The ETC meter is equipped with a temperature sensor, while the ETPC meter is equipped with both a temperature sensor and a pressure sensor. The use of both temperature and pressure sensors in the meters is for the purpose of standardizing the consumed volume. The ETC meter is used in low-pressure applications such as residential use, but for higher-pressure applications, such as industrial use, the ETPC meter is used.
