Abstract
Official abstract text for this publication.
An apparatus and method for monitoring a flow of liquid in a pipe are provided. The apparatus may include a temperature sensor attached to a pipe of a heat exchanger system to measure a temperature of the pipe, and a controller to determine whether a liquid is present in the pipe, based on a change in the measured temperature.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for monitoring a flow of liquid in a pipe, the apparatus comprising: temperature sensors attached at a predetermined first point outside or inside a pipe, and a second point at a distance spaced apart from the first point of a pipe to measure a temperature of the first point of the pipe and a temperature of the second point of the pipe, respectively; and a controller having a display unit with a first indicator ON that turns on when it is dete…
