Abstract
A system that includes a container containing a fluid, a fluid line coupled with the container, and a pump configured to pump the fluid out of the container through the fluid line. The system further includes a sensor that includes a wireless transmitter. The sensor is configured to sense the pressure in the fluid line and to periodically transmit, using the wireless transmitter, an alarm message when the pressure reaches an alarm threshold.
