Frequently Asked Questions

Q: What sizes does the HELTC vertical float switch come in?

A: The HELTC Mini Vertical Float Switch is available in four sizes: 65mm, 100mm, 150mm, and 200mm, making it suitable for a wide variety of tank depths and installation requirements.

Q: Can this stainless steel float switch be used in chemical or industrial liquids?

A: Yes. Thanks to its stainless steel SUS construction and wide operating temperature range (-30°C to +125°C), this float switch is suitable for use with water, certain chemicals, and various industrial liquids. Always verify material compatibility with your specific liquid before installation.

Q: How do I install the vertical water level sensor — at the top or bottom of my tank?

A: This float switch can be mounted either at the top or the base of your tank. Install it at the top to detect a rising liquid level (e.g., to trigger a shutoff when the tank is full), or at the base to detect a falling level (e.g., to trigger a pump or alarm when levels drop low).

Q: Does this float switch require any external power or batteries?

A: No batteries are included or required for the switch mechanism itself. The float switch operates purely on mechanical principles — as the float rises or falls with the liquid level, it opens or closes the circuit via the connected cable. You will need to wire it into your own control circuit or alarm system.
