1. A device for monitoring fluid levels comprising: housing with a front assembly and a rear assembly; a sensing assembly, an analog to digital converter; wherein the sensing assembly comprises a rectangular member, with a top horizontal leg, a bottom horizontal leg, a left vertical leg, a right vertical leg, a bottom hook projecting from the left vertical leg out of said housing; a top hook projecting from the right vertical leg out of said housing, up to four strain gauges; wherein the top and bottom horizontal legs are tapered and hollow at their centers; wherein the top and bottom hooks oppose each other and are planar to the rectangular member; wherein the one vertical leg is attached to the housing and the left vertical leg, and the top and bottom horizontal legs are free floating; wherein the up to four strain gauges are arranged along the horizontal legs; wherein the up to four strain gauges are connected to the analogue to digital converter; wherein the analogue to digital converter, a speaker, a view screen, a programming switch, an on/off switch, and a wireless transmitter connect to a microprocessor; wherein said power source is connected to a microprocessor; wherein said strain gauges detect deformations in the rectangular member caused by suspension of a weighted object from the bottom hook member and communicate that distortion through the analogue to digital converter to the microprocessor; wherein the programming switch, or peripheral device connected to the device, either through a peripheral port or wirelessly is used to set an initial weight or volume and/or a threshold value; wherein when the threshold value is reached, the microprocessor activates the speaker, causing it to emit an audible alarm and causes the view screen to indicate a visual alarm; wherein said view screen is attached to and visible through the front assembly, is status backlit in either red or green color, each color corresponding to low or filled fluid levels, respectively; wherein backlighting blinks and flashes once the threshold value is met and passed; wherein the wireless transmitter notifies a remote location once threshold value has been met or exceeded. |
