摘要： An apparatus is proposed for indicating the level of fuel or other liquid contained in a tank. The apparatus consists of a cylindrical casing closed at its two ends by two suitably shaped disc-like covers, and internally comprising two guides on which there slides a float provided with a slot within which there is engaged a rod having its ends connected to a rotary moving element which comprises on its top a contact which slides along a resistor installed on the upper disc-like cover of the cylindrical casing. As the height of the float varies within the cylindrical casing, which is suitably holed to allow the liquid to enter or leave, the position of contact along the resistor varies with corresponding variation in the electrical signal measured at its output.

摘要： An optical liquid measuring system for measuring the amount of flammable liquid in a storage tank consisting of a pair of encoder disks that are operatively connected to a pair of floats through a pair of pulley systems. The floats are designed so that the first float will float on top of flammable liquid such as gasoline, and the second float will float on top of water. Optical encoder reader heads or optical connectors are located proximate to the respective encoder disks to receive light that is reflected by or transmitted through the encoder disks. The optical connectors include a plurality of optical fibers that receive the light from the encoder disks and transmits signals to a CPU. The CPU then takes the information derived from the received signals and uses an algorithm to accurately calculate the amount of gasoline and water in the storage tank.

摘要： A low fluid sensor for an internal combustion engine. The sensor includes a base with helically threaded post and a float slidably mounted on the post. The float rotates about the post as it moves longitudinally along it. In the preferred embodiment, eccentric mounting of the assembly along with its lobe shape act in concert with the pitch of the screw threads and fluid viscosity to dampen the buoyant movement of the float against fluid turbulence. At a predetermined level a latch spring on the float contacts an ignition circuit terminal and grounds the engine ignition circuit. A catch holds the float at the predetermined level, preventing engine starting, so that the sensor may only be reset by addition of fluid and re-insertion of the dipstick.
摘要翻译：用于内燃机的低流体传感器。传感器包括具有螺旋螺纹柱的底座和可滑动地安装在柱上的浮子。当浮体沿其纵向移动时，浮子围绕柱旋转。在优选实施例中，组件的偏心安装及其凸起形状与螺纹螺距和流体粘度一致，以抑制浮子的浮力运动抵抗流体湍流。在预定水平上，浮子上的闩锁弹簧接触点火电路端子并使发动机点火电路接地。捕捉器将浮子保持在预定水平，防止发动机起动，使得传感器只能通过添加流体和重新插入量油尺来重置。

摘要： A fluid measurement gauge is principally used to measure the fluid level in large underground storage tanks, such as for storing gasoline at service stations. A housing (12) is positioned vertically in the fluid and includes a leadscrew (30) which is driven by a stepper motor (100). A nut (176) is mounted for longitudinal movement along the leadscrew. A float (160) encircles the housing and includes a magnet (164) at the surface of the fluid level. A magnetic sensor, such as a Hall-effect switch (188) is mounted on the nut and driven in selected steps downward to encounter the magnet mounted in the float. A reference position is marked at the top of the housing and the fluid level is measured downward from the reference position by detecting the magnet by operation of the magnetic sensor. An additional float (166) can be provided to detect the interface between two fluids such as gasoline and water. The second float is further provided with a magnet (168) to be detected by the magnetic sensor. In addition, temperature sensors (150,152,154), such as thermistors, can be mounted near the housing to measure the temperature of the fluid for compensation to standard conditions. An electronic circuit board (112) can be included within the fluid measurement gauge to provide an integral unit for making periodic, unattended fluid measurements.

摘要： A fluid level monitor is provided for use in a tree stand. The tree stand defines a fluid-containing well for receiving a cut end of a tree. The monitor includes a body, and an indicator located on the body. A fluid sensor is operatively connected to the indicator, and is adapted for communicating with the well of the tree stand. When the fluid contained in the well reaches a predetermined minimum level, the fluid sensor causes the indicator to emit an alarm indicating a low level fluid condition in the well.
