Most Suitable Level Sensors for Chemical Tanks

Plastic submersible level sensors are an essential alternative for detecting acid levels in tanks, especially in hostile settings where other types of sensors may be ineffective. These sensors are made out of a plastic enclosure that houses the sensing element and electronics and is submerged in acid. The sensor element is commonly composed of corrosive acid-resistant plastic or ceramic.

One of the primary benefits of plastic submersible level sensors is that they may be exposed directly to acid, eliminating the need for a separate process connection. They are useful for situations where other types of sensors may fail due to corrosion or chemical assault and may be utilized with a wide spectrum of acids.

The sensors are available in a variety of types, such as float, vibrating fork, and displacer, each with its unique working principle.

Float sensors have a buoyant element that rises and lowers in response to the acid level. The location of the float is utilized to calculate the acid level.
Vibrating fork level sensors function by producing a mechanical vibration using a fork-like device and monitoring the change in oscillation frequency when the fork comes into contact with the acid.
The buoyancy force applied on a displacer element is measured using Displacer Level Sensors. The displacer will move in response to changes in the acid level, and the sensor will detect the location and relay the level signal.

Plastic underwater level sensors also have the benefit of being compact and lightweight, making them simple to install and maintain. They can be built to be explosion-proof and fitted with an alarm or signal output to alert the operator in the event of a high or low level.

Plastic submersible level sensors may not be ideal for high-temperature applications or acids with extremely low pH values because they may not tolerate the severe circumstances. Temperature, pressure, and the chemical composition of the acid may also impact the accuracy and repeatability of some sensors, such as float sensors.

Overall, plastic submersible level sensors are a dependable and cost-effective alternative for measuring acid levels in tanks, especially in severe situations. They are helpful for process control and safety applications because they can offer continuous and accurate level measurement.
