摘要： A latching fluid level switch which includes an elongated shaft member having a lower end and an opposite upper end with both ends containing a buoyant float member. The upper end is pivotally anchored to a tank wall and capable of having its lower end being moved between two distinct angular positions depending on the level of the liquid in said tank acting on said float member and having a first higher buoyancy angular position representing a high liquid level endpoint, and a second less buoyant angular position representing a lower liquid level endpoint. The float is maintained at each distinct angular position such that once triggered at one liquid level endpoint the float will maintain and hold that angular position until reversibly triggered at the other liquid level endpoint.

摘要： A sensor is coupled to a reservoir for generating a first signal responsive to the liquid level therein falling below a first level spaced above an output port and indicative of a reserve level of liquid remaining. A pump is coupled to the reservoir for pumping the liquid therefrom in metered volumes and responsive thereto transmitting a volume pumping signal. An integrator receives and integrates the volume pumping signal, and then generates, after receiving the first signal, an output signal indicative of the volume of the liquid remaining in the reservoir. An indicator is coupled to the integrator for displaying the output signal.

摘要： A water gauge in accordance with the invention includes a base and a spherical indicator ball. The base includes a container having a side wall, a bottom wall and a post. The spherical indicator ball has a yellow initial signal hemispherical wall and a red final signal hemispherical wall connected to an axle along a circumference. The axle is supported by the side wall of the container. The yellow initial signal hemispherical wall is heavier than the red final signal hemispherical wall. The spherical indicator ball has a channel in the middle of the red final signal hemispherical wall. Initially, the post is positioned into the channel so that the yellow initial signal hemispherical wall is up and visible. The water gauge is positioned on a lawn to be watered. When watering has added a sufficient amount of water to the container to float the ball above the top of the post, the ball is rotated by gravitational force to position the heavier hemispherical wall in the water. Thus, the water gauge is adapted to indicate when water droplets falling onto a lawn have reached a predetermined amount.
摘要翻译：根据本发明的水表包括基座和球形指示球。底座包括具有侧壁，底壁和柱的容器。球形指示球具有黄色初始信号半球形壁和红色终端信号半球形壁，其沿圆周连接到轴。轴由容器的侧壁支撑。黄色的初始信号半球形壁比红色最终信号半球形墙重。球形指示球在红色终端信号半球形墙的中间有通道。最初，柱位于通道中，使得黄色的初始信号半球形壁向上并且可见。水表位于要浇水的草坪上。当浇水已经向容器中加入足够量的水以将球浮在柱的顶部上方时，球通过重力旋转以将较重的半球形壁放置在水中。因此，水表适于指示落在草坪上的水滴何时达到预定量。

摘要： An audible low-fuel alarm (50) for a pressurized propane fuel tank is disclosed. A Hall-effect sensor (57) is mounted in relation to a magnet (35) which is rotated in response to the level of fuel within the propane tank. When magnet (35) is rotated to a position to indicate a low fuel condition, the Hall-effect sensor (57) activates a buzzer 53. A mercury switch (55) prevents false low fuel alarms and conserves battery power during inflation of the balloon envelope.

摘要： A level indicating device for liquid filled containers is provided having a floating sensing element which is operatively connected with a signal device, the sensing element having several, preferably three floats arranged on a single plane. The floats are supported on lever arms which are interconnected with each other at a central union. The lever arm union is supported for free movement in a guide disposed approximately in the center of the container and approximately vertically aligned with the surface of the liquid when the liquid is at rest. The longitudinal movement of the lever arm union in the guide caused by changing liquid levels is transmitted to a signal device for monitoring the liquid level.
