Is the Submersible Liquid Level Sensor Really The Best Choice?
Submersible liquid level sensors are typically used in chemical tanks and other industrial applications to measure the level of liquids. They consist of a sensor probe that is immersed in the liquid and a signal transmitter that sends the measurement data to a control system. The sensor probe can be made of various materials, such as stainless steel, titanium, or PVC, depending on the chemical compatibility of the liquid being measured.
The submersible liquid level sensor probe is usually connected to the signal transmitter via a cable, which can be either a two-wire or a three-wire configuration. The two-wire configuration is usually preferred because it is simpler and less expensive, but it is less accurate than the three-wire configuration. The signal transmitter converts the measurement data into a 4-20mA loop-powered signal, which can be easily integrated into a control system.
One of the main advantages of submersible level sensors is that they are not affected by vapor, foam, condensate, or turbulence. This makes them ideal for use in chemical tanks, where these conditions are often present. Additionally, submersible liquid level sensors are relatively easy to install and require no programming. They are also robust and durable, making them suitable for use in harsh industrial environments.
In contrast, ultrasonic-level sensors can be affected by foam, vapor, and condensation, which can lead to inaccurate measurements. Additionally, ultrasonic sensors are not suitable for use in some applications, such as tanks with turbulent liquids or high levels of noise.
Radar level sensors are also accurate and reliable, but they are more expensive and can be affected by foam and vapor. They are more suitable for larger and more complex tanks, and applications where high accuracy is required.
In conclusion, the Submersible liquid level sensor is considered to be the best sensor for chemical tank level measurement as it is a cost-effective, easy-to-install, durable and accurate solution for chemical tanks and other industrial applications.
