For most plastic granule and pellet applications, rotary paddle level switches and vibrating fork level switches are practical choices. Rotary paddle type is economical for bulk solid detection, while vibrating fork type is suitable for compact hoppers and low-wear applications. Shao Level provides rotary paddle level switches, vibrating fork level switches, capacitance level switches, RF admittance level switches and other industrial level measurement products for plastic granule hoppers, storage silos and automatic feeding systems.

Correct installation is just as important as choosing the right level switch. Even high-quality sensors may create false alarms, unstable signals or mechanical damage if installed in the wrong position. This guide explains how to properly install level switches in tanks, silos and hoppers.

A vibrating fork level switch is a good choice for many powder hopper applications, especially when compact structure, no rotating paddle and stable point level detection are important. However, the final selection should always match the powder characteristics, hopper structure and control system requirements. Shao Level provides vibrating fork level switches, rotary paddle level switches, RF admittance level switches and other industrial level measurement products for powder hoppers, silos, tanks and automation systems.

Choosing the right level switch means matching the detection principle, installation condition, and control purpose to the real process. Reliable performance comes from application fit, not from choosing a device by name alone.
