As an electronics engineer, I feel, it is my duty to update my fellow woman buddies about latest happenings and the reason behind this article is same. Here, I am going to talk about Liquid sensors.
Liquid level sensors are devices that help in the measurement of substances that flow, including liquids, slurries, etc. Gravitational force helps the liquid to become level in the container holding them. The substance that needs to be measured can be inside a container or can be in its natural forms like a pond or a river. Either continuous or point values can be the form of level measurement. Within a specified range, the level can be measured by continuous level sensors thereby determining the exact amount of substance in a certain place. Conversely, whether the substance is above or below the sensing point is exhibited by point-level sensors. Generally, excessively high or low levels can be detected by the latter.
Several physical and application variables affect the selection of the optimal level monitoring method for processes like industrial and commercial. The selection criteria include pressure or vacuum, temperature, density, chemistry, the dielectric constant of the medium, agitation (action), vibration, acoustical or electrical noise, mechanical shock, tank or bin size, and shape.
Point level detection of liquids
A method known as Pulse-Wave Ultrasonic which is non-invasive is used to transmit a signal that consists of short bursts of ultrasonic energy.
Magnetic and mechanical float
The mechanical switch's opening or closing, either through direct contact with the switch, or magnetic operation of a reed is involved in the principle behind magnetic, cable, mechanical and other float level sensors.
Dangerous conditions may result, where there is no electric power, and in applications involving heavy sludge or slurry, pneumatic level sensors are used.
For the point level detection of a wide range of conductive liquids such as water, conductive level sensors are ideal and they are also well suited for highly corrosive liquids.
These liquid sensors are widely used in various industries, in the medical field, irrigation field, etc. They are apt where there is not enough space for the installation of big level sensors. They are compact and can just be fit along with the industry's equipment. They are very easy to install and operate on. They are designed for easy use and any layman can fit them when necessary. There are absolutely no chances for unexpected jamming and failure of the apparatus as the all kinds of sensor are very durable and can handle immense pressure quite comfortably. Where there is a meter installed which reads the level of liquid and indicates the current level some apparatuses require a reading mechanism. Unlike the old methods where just a warning signal would show up on reaching a particular level, this is provided in these level sensors. Even suction control valve plays a role here. As they are made of very robust and trust able material they can handle any kind of liquid flowing through as they are designed in that manner. There are various types of connectors which can be fitted with these sensors and hence the compatibility is not an issue here. It can handle very high pressure and does not wear out that easily. All these advantages make the use of liquid level sensors more common.
