Inside distribution networks the pressure and the temperature of the gas must be adjusted before it enters residential utilities. The high pressure of the gas is not suitable for consumers' use. The reduction of pressure is therefore also connected to a reduction of temperature, and the whole procedure requires constant remote supervision and monitoring. In this case, the use of devices such as WE151 or WE152 is suggested to monitor and manage first stage gas pressure reduction stations.
Once implemented with specific sensors, the device can read the main parameters of the system: input and output pressure, filter differential pressure, temperature and level of preheating liquid. According to the acquired parameters, the device can then send alert notifications to the appointed operators or perform automated corrective actions, in order to bring values back within safety ranges. It can directly interact with pressure relief valves and automatically intervene in the gas odorization process. WE151 and WE152 can also manage an alarm notification system in case of gas leaks, intrusions, power supply failures or other anomalies.
