Typical connection example

Connecting to a field network makes it possible to collect and manage various information from pressure sensors. This allows for the construction of information systems for batch monitoring of liquid levels at various locations, predictive maintenance, changeovers, quality management, and more.

The following example includes a network-connected level sensor.

Remote monitoring using digital data

Real-time remote monitoring makes it possible to obtain accurate liquid level information from tanks located off-site. This allows for quicker responses to problems, leading to reduced downtime.
