Frequently Asked Questions

What is the LUMENITE Liquid Level Probe used for?

The LUMENITE Liquid Level Probe is used for point-level sensing in industrial tanks and vessels. It detects liquid presence or absence at a specific level, commonly applied in water treatment, chemical processing, and oil & gas systems. The stainless steel construction suits corrosive or high-temperature environments.

What are the specifications of the LUMENITE Liquid Level Probe?

This LUMENITE probe has a 1/2-inch NPT process connection, a 12-inch probe length, and stainless steel construction. It is a single-probe unit with manufacturer part number PHST12Q12"UN. The NPT type allows direct threaded mounting into tank openings.
