4. Installation method
Pressure transmitters are usually installed directly through pipelines. It is recommended to install a valve once for ease of installation, commissioning, and maintenance.
When the temperature of the medium is higher than 85 ℃, a certain length of pressure pipe needs to be installed to facilitate the cooling of the medium, otherwise it may cause inaccurate measurement or even damage to the transmitter.
