ABSTRACT:
An apparatus is provided for use in monitoring the level and temperature of a liquid flowing through a horizontally extending line that is to remain full of liquid, wherein the temperature of the liquid is to be maintained below an established acceptable value. The apparatus includes a chamber interposed in the line and formed with an enlarged transverse cross-sectional area, and is disposed at least partially above the line. The chamber is closed except for an inlet and outlet in fluid communication with the line. A sensing assembly is provided within the chamber for sensing the level and temperature of the liquid flowing through the chamber. A control assembly measures the liquid level and temperature sensed by the sensing assembly and activates an alarm when either the level of the liquid in the chamber drops below a predetermined level or the temperature exceeds a predetermined value above the established acceptable value. Structure is also provided within the chamber for relieving trapped air from the chamber so that the trapped air does not force the liquid level below the sensing means.
