Abstract:
A system and method for monitoring inefficient flow rates in a liquid-flow distribution system, such as that which is used in agricultural liquid application equipment. This may include blockages or punctures in a liquid line. The system generally includes a plurality of gauges for monitoring the supply line flow rate in a liquid application system which are monitored by a number of sensors. Immediate feedback is presented to the operator of the vehicle inside the cab. The system alerts the operator when a blockage, loss, or increase of flow rate has occurred in one of the liquid lines. The system may merely indicate that one of the lines is blocked, or the system may be more sophisticated such that it can indicate which line is blocked and adjust the flow in that line in an attempt to clear the blockage.
Abstract:
There is provided an apparatus and method for estimating fluid mass in a cryogenic tank that holds a multiphase fluid comprising a liquid and a vapour. The apparatus comprises a level sensor, a pressure sensor and a computer. The level sensor provides a parameter representative of a level of the liquid. The pressure sensor provides a pressure signal representative of vapour pressure inside the cryogenic tank. The computer is operatively connected with the level sensor and the pressure sensor to receive the parameter and the pressure signal, and is programmed to determine the level from inputs comprising the parameter, to calculate a first volume of the liquid from inputs comprising the level, and to calculate a first mass of the liquid from inputs comprising the first volume and the pressure signal.

The apparatus further includes a data transmitter/microprocessor assembly in electronic communication with the sensor assembly and structured to be effective in receiving the first and second signals from the first and second sensor components, respectively, and processing said first and second signals into data representing a height of liquid in a liquid storage tank.
Abstract:
A liquid level indicating system (10) with a chain (12) connected at an upper portion (16) to a weighing device (14) in a container (18) for liquid (20). The weight of the chain (12) sensed by the weighing device (14) corresponds substantially to the effective weight of the portion of the chain above the level of the liquid (20).
Abstract:
An improved leak detection float system for use in underground storage tank (10) containing fuel (20) wherein the float system utilizes an elongated hollow test probe (30) extending downwardly into an underground storage tank (10) and into the fuel (20) stored therein. A microprocessor (70) is contained in an upper compartment (46) of the test probe (30) along with control electronics (80). A rod (40) is centrally affixed in the lower portion (42) of the test probe (30) and a float (100) is disposed around the rod (40), but within the test probe (30) so as to float on the surface (22) of the fuel (20). The float (100) uses tapered edges to minimize offset error due to surface tension. An excitation transducer (50) is placed above the float (100) on the rod (40) which produces vibrational waves (55) down the rod (40) having a predetermined frequency, power, and duration. The vibrational wave breaks the surface tension existing between the float (100) and the fuel (20) so that the float (100) can obtain a position within the fluid (20) based upon the buoyancy of the float (100) in the fluid (20).
Abstract:
A fuel tank assembly is provided that includes a semi-rigid fuel tank having an upper wall and a lower wall, and a support member coupled between the upper wall and the lower wall. The support member is configured to maintain a predetermined distance between the upper wall and the lower wall when the lower wall of the semi-rigid fuel tank is moved due to a force. The fuel tank assembly can further include a low fuel reservoir disposed at least partially below the lower wall, the low fuel reservoir configured to define a space where fuel drains when the rest of the fuel tank is empty, the low fuel reservoir having a predetermined volume, and a low fuel sensor operably associated with the low fuel reservoir, the low fuel sensor defining a low fuel level activation point.
