How to Choose a Liquid Level Sensor?
Choosing the right liquid level detection sensor depends on your application requirements, including the type of liquid being measured, the application environment, and accuracy standards.
Factors to Consider When Purchasing a Liquid Level Detection Sensor?
Define the Type of Liquid to be Measured
Water/Non-corrosive Liquids
For detecting common liquids in water tanks, reservoirs, and HVAC systems, float-type liquid level sensors are the first choice. These liquids are stable and do not react. Float-type liquid level sensors are also inexpensive and have a long lifespan, making them ideal for detecting common liquids.
Highly Corrosive/Hazardous Liquids
For some chemical liquids, strong acids, and alkalis, non-contact liquid level sensors should be prioritized. For example, ultrasonic liquid level detection sensors and radar liquid level sensors can accurately measure liquid level data without direct contact with the liquid.
The GRLM-70 series radar level meter is a good choice, with a measurement range of up to 40 meters and 10 models available for different scenarios.
Foamy/Thick Liquids
Liquids containing foam, sediment, or high viscosity can interfere with certain sensing technologies. Radar waves can penetrate foam and only reflect off the liquid, making radar liquid level sensors ideal for non-contact measurement in foamy and heavy steam environments. Capacitive liquid level sensors can measure viscous liquids non-contactly or via probes, unaffected by sediment buildup.
Application Environment
For applications in extreme weather or harsh environments, sensors with high protection ratings and strong resistance to environmental interference should be selected.
Accuracy
Basic level detection: Float switches or fiber optic liquid level sensors are usually sufficient.
Continuous level measurement: Ultrasonic, radar, capacitive, or pressure liquid level sensors provide real-time level data.
High-precision applications Require Sensors with a minimal error range and long-term stable performance.
In summary, when selecting a liquid level sensor, it is essential to consider the type of liquid being measured, the application environment, and the required accuracy to ensure optimal matching.
