ABSTRACT:
A system for remotely sensing a low level of a fluid in a tank, such as the low level of oil in an internal combustion engine. A sensing tube projects through a housing defining an oil reservoir therein, which sensing tube is disposed with its open lower end positioned at an elevation which defines the low or add level for the oil. The sensing tube has its upper outer end connected through a suitable conduit to a remotely located actuator. The actuator, preferably manually actuated, transmits a determined mass of air through the conduit means into the sensing tube. A visual indicator senses changes in pressure within the sensing tube. When the lower end of the sensing tube is immersed in oil, the mass of air supplied to the system effects a pressure increase which is recorded on the indicator, thus indicating that the oil level in the reservoir is above the low or add level. However, if the oil level is low so that the lower end of the sensing tube is not immersed in oil, then the mass of air passes into the open upper region of the reservoir without creating any significant pressure pulse.
