摘要： A float-type liquid level gauge assembly (20) is provided for measuring the level of a liquid, such as liquefied petroleum gases, in a tank. The liquid level gauge (20) includes a gear housing (50) which provides for an efficient way to couple gears together as well as to accurately assemble and align the components of a liquid level gauge. The liquid level gauge (20) includes a movable pivot arm assembly (70) supporting a float arm assembly (74). A gear on the pivot arm assembly (70) is coupled with a pinion gear (65) located in the gear housing (50). The pinion gear (65) has a shaped passageway (69) which accepts a similarly shaped drive shaft (40) which has a magnet (36) at one end. The magnet (36) extends into a passageway (44) on the lower side (30b) of a gauge head (30) so as to be magnetically coupled to a level indicating dial assembly (32) provided on the upper side (30a) of the gauge head (30). The shaped drive shaft (40) only allows for a limited number of ways the drive shaft (40) will fit into the pinion gear passageways (69), thus allowing efficient alignment of the magnet (36) with the level indicating dial (32).

摘要： A Time Domain Return measurement system for measuring liquid level, linear movement or other measurements which includes a first and second electrode, the second electrode spaced from the first electrode to define a gap, and an electronics assembly connected to the first and second electrodes equipped with a generator for transmitting an electromagnetic signal for propagation along the electrodes. The signal generator has a first analog timing circuit for actuating a slow-rising function of voltage versus time, a second analog timing circuit associated with the first analog timing circuit for actuating a fast-rising function of voltage versus time, and a receive circuit electrically connected to the electrodes, the receive circuit being activated for receiving return echo data associated with the electromagnetic signal transmitted when the fast-rising function is equal or greater than the slow-rising function to determine the position of the second medium with respect to the electrodes.

摘要： A time domain reflectometer (TDR) transducer (10) for determining a level (24) of liquid (16) in a container (12) includes a first electrode (34) and a second electrode portion (36) with a measuring volume (114) therebetween for receiving material (16) to be measured. The second electrode portion (36) has a shielded electrode section (36A) isolated from the first electrode (34) and an unshielded electrode section (36B), such that an energy pulse propagates along the shielded electrode section (36A) without signal loss, and boomerangs along a second opposite direction across the first conductive electrode portion (34), the measuring volume (114) and the unshielded electrode section (36B) where partial reflection of the pulse occurs at least at the interface (24) of the material (16) to create a return echo that travels in reverse direction, boomeranging back through the shielded electrode section (36A) for analysis by an electronic assembly (32).

摘要： A capacitive gauge, suitable for measuring a fluid level in a container, includes upper and lower capacitive elements. Also provided is a control unit for calculating the fluid level in the container based on the capacitance of the upper and lower capacitors and a dielectric constant of the fluid in the container. The control unit also includes functionality for determining and storing the dielectric constant of the fluid in the container. The dielectric constant of the fluid is determined by first verifying whether the lower capacitive element is completely submerged based on a comparison of a measured capacitance of the upper capacitor to a reference capacitance of the upper capacitor. If the lower capacitor is verified to be submerged, then the dielectric constant of the fluid is calculated based on a measured capacitance of the lower capacitor.

摘要： A float-type liquid level gauge is provided for measuring the level of a liquid such as LPG within a horizontally oriented cylindrical tank (228). The gauge includes a movable pivot arm (212) supporting a float arm assembly (225) and coupled by gears (207, 214) to a magnet shaft (206, 208) and magnet (210) mounted in a rigid support arm (204) through a sideways-securing shaft channel (209). The support arm is connected to the lower side of a gauge head (202) and the magnet extends into a passage (52) in the gauge head so as to be magnetically coupled to a level indicating dial (226) provided on the upper side of the gauge head. The lower portion (302) of the support arm is angled and offset with respect to a longitudinal axis (265) such that a high ratio can be obtained between the gears while still permitting the components of the gauge to pass through the opening of a standard pressure fitting (234).

摘要： An electronic liquid level gauge assembly includes an electronic display located in a housing connected to a tank. The display has first and second display portions for indicating liquid level condition. A first electronic sensor senses a change in magnetic field of a magnet associated with a liquid level transducer, with magnet rotation being proportional liquid level change. A processor determines a temperature-compensated liquid level condition by correlating the liquid level signal with temperature measurement of the liquid. A temperature-compensated vapor space can also be calculated based on tank information and properties of the liquid. Signals related to the temperature-compensated liquid level and vapor space are sent to the display and wirelessly transmitted to a smart phone or the like for remotely viewing the tank information. The smart phone also includes a special app for sending information, firmware updates, and display configuration data to the electronic gauge assembly.
