Industrial FLS-VM-400 Float Liquid Level Switch

PROsense FLS-VM-400 Float Liquid Level Switch is an industrial-grade level-sensing device that uses a float to detect liquid presence and produce a switch action as the level changes. The unit has an insertion length of 1.63 inches and a diameter of 1.13 inches, giving it a compact footprint suitable for restricted spaces in tanks, vessels, or inline installations. This model is designed to provide level indication in industrial environments, supporting straightforward integration into level-control or alarm systems that rely on on/off signaling based on liquid height. The FLS-VM-400 designation helps maintenance teams identify the specific variant and ensures compatibility with replacement parts within the PROsense line. Its small size and basic form factor make it a practical choice when space is at a premium and sensing is required in a low-profile package.
