Level sensors can be customized in terms of probe length, mounting type (thread mounted or flange mounted), output signal, and power supply such as 12V DC or 24V DC.
Customization ensures better compatibility with specific tank structures and operating conditions.
Inaccurate readings are usually caused by incorrect sensor selection, improper installation, or unsuitable sensing technology.
Factors such as foam, condensation, buildup on probes, or strong turbulence should be considered during selection to ensure stable and reliable measurement.
