1. An apparatus comprising:
- a sensor configured to measure a physical variable, and to generate data representative of the measured physical variable; and
an Ethernet cable connectable to the sensor, the Ethernet cable having POE (power over Ethernet) capability so as to both transmit the data from the sensor over an Ethernet network and also deliver power to the sensor from a power source connected to the Ethernet network.

Abstract
Ethernet-enabled measurement systems are disclosed that are POE compatible. The measurement systems are configured to measure a physical variable, and to generate and communicate data representative of the measured physical variable. The physical variable may include, but is not limited to, fluid pressure, fluid flow rate, and fluid flow ratio. The POE compatible measurement systems are configured to communicate the data through a POE-capable cable over an Ethernet network in accordance with Ethernet networking protocol. The measurement systems are further configured to receive power through the same POE-capable cable from a power source connected to the Ethernet network.
