Best Level Sensors for Liquid Tank Level Application
The amount of acid in tanks can be measured using plastic submersible level sensors, especially in difficult situations where other kinds of sensors would not be appropriate.
These sensors are made of a plastic housing with electronics and a detecting element that is submerged in acid.
Typically, the detecting element is constructed of ceramic or plastic, both of which are resistant to corrosive acids.
Plastic submersible level sensors have a number of benefits, including the ability to be directly exposed to acid, which avoids the need for a separate process connection.
They are useful for applications where other types of sensors can malfunction due to corrosion or chemical attack and can be utilized with a variety of acids.In situations where other types of sensors can malfunction owing to corrosion or chemical assault, they can be utilised with a variety of acids and are appropriate.
The sensors come in a variety of types, such as float, vibrating fork, or displacer, each with a unique operating principle.
A buoyant component that rises and falls with the acidity of the sample is included in float sensors. Acid level is calculated using the float’s location.
In order to detect the presence of acid, vibrating fork level sensors produce a mechanical vibration with the help of a fork-like component. As the fork comes into contact with the acid, the vibration frequency changes, and this is how they operate.
The buoyancy force exerted on a displacer element is measured using displacement level sensors.
Submersible level sensors are meant to be entirely or partially submerged in a liquid in order to measure its level. There are various varieties of submersible level sensors, each of which works slightly differently, but the majority of them are divided into two categories: contact and non-contact sensors.
Touch sensors: These sensors make direct contact with the liquid being measured and employ various physical concepts to determine the level, such as:
Hydrostatic pressure sensors: These devices measure the pressure of a liquid on the sensor itself. They work on the concept that the pressure imposed on a fluid is proportionate to its depth. They measure the hydrostatic pressure on the liquid’s surface and utilise this data to compute the level.
Capacitance sensors operate by measuring the capacitance of the liquid on the sensor. Capacitance is a material’s ability to store an electrical charge. They function by passing an electrical charge through the sensor and detecting the amount of charge contained in the liquid. They then utilise this data to compute the level.
Non-contact sensors: These sensors do not come into direct contact with the liquid being measured and measure the level using various physical concepts, such as:
Ultrasonic sensors create sound waves and measure the time it takes the sound wave to travel through the liquid to the surface and back. This information is used to compute the level.
Radar sensors function by producing radio waves and monitoring how long it takes the radio wave to pass through the liquid to the surface and back. This information is used to compute the level.
To summarise, submersible level sensors measure the level of a liquid in a container. This measurement can be performed in a variety of ways, including detecting pressure, capacitance, and ultrasonic/radar signals, which are then analysed to determine the liquid level.
