EMPTY PRODUCT DETECTOR

The alarm mechanism of the invention signals the absence of a liquid from a source of aqueous liquid. The alarm mechanism comprises an alarm body having an inlet port and an outlet port; the inlet port in liquid communication with a source of liquid, the outlet port in liquid communication with a use locus. The alarm mechanism additionally comprises a float chamber placed in liquid parallel communication with the inlet port and the outlet port. The float chamber contains a float operably connected to a mechanical alarm. The float, as the chamber is emptied of liquid, reaches a position wherein a "low or empty product" signa l is generated. The apparatus operates by passing liquid through the body. As liquid in the source of liquid is depleted and is no longer available for passage through the body, the body becomes emptied of liquid as the source of pressure removes liquid from the body and particularly from the chamber causing the float to reach a position generating a signal.

LIQUID LEVEL SENSOR HAVING A VIRTUAL RING

A liquid level sensor for conductive liquids having a virtual bias ring to prevent false "full" indications. The sensor is an inexpensive conductive probe that can be installed in any tank or container used to contain a conductive liquid. The build up of residue such as conductive fluid that fails to drain on the inside of the container wall and probe pieces can cause a short between the probe and ground. This situation will result in falsely showing that the level of the liquid being measured is at least at the minimum predetermined requirement even though the actual level may be far less than that amount. The bias ring is a virtual "ring" that is provided around the insulating base of the sensing probe between the probe tip and the top inside of the tank. The probe is then given a charge (positive for negative ground systems) which interrupts the current path between the sensing tip of the probe and ground via the conducting residue. Consequently, the sensor will read correctly despite ...

Systems and Methods for Measuring Levels of Liquids of Different Densities in Containers

Systems and methods for measuring or determining the level or amount of multiple immiscible liquids of different densities in containers utilize multiple floats, with each float having a density less than the density of the liquid to be measured but greater than the density of the next less dense liquid (or fluid) in the container. In this fashion, the position of each float can be determined and used to determine the levels of the various liquids using a single three-terminal potentiometer. A method includes measuring first and second electrical signals corresponding to first and second locations of actuation of the potentiometer. A system includes a three terminal potentiometer capable of magnetic actuation at two locations, a first float configured to magnetically actuate the potentiometer at a first location, and a second float configured to magnetically actuate the potentiometer at a second location that differs from the first location.

Liquid level sensor having a virtual ring

A liquid level sensor for conductive liquids having a virtual bias ring to prevent false “full” indications. The sensor is an inexpensive conductive probe that can be installed in any tank or container used to contain a conductive liquid.

一种水位报警器

本发明提供一种水位报警器，水通过通孔渗入壳体内，随着水位的上升，浮箱也随着上升，并推动推杆，当推杆上的触点碰到触点开关后扬声器发出警报，及时提醒人们，使用方便，灵敏度高，使用寿命长，制作成本低；本装置提供吸盘、安装耳和螺钉配合的两种固定方式，满足对不同容器壁、水池墙壁的吸附固定要求；同时推杆与壳体之间的贯穿孔粘贴有吸水膨胀橡胶，当水漫到贯穿孔时，吸水膨胀橡胶会吸水膨胀堵住贯穿孔，防止水通过贯穿孔进入报警装置，引起触电和触电开关之间的短路。
