This document introduces the features and uses of Switch-Tek™ Vertical Buoyancy Liquid Level Switch LV10 Series
The Flowline LV10 Series Vertical Buoyancy Liquid Level Switch consists of a float, magnet reed switch, and baffle body designed to eliminate switch chatter. The device operates by detecting when the probe becomes immersed in liquid, causing the float to become buoyant and elevate the magnet to change the reed switch state. It is available in two wetted material versions: Polypropylene (PP) and Polyvinylidene Fluoride (PVDF).
The manual covers specifications such as accuracy, repeatability, and temperature ranges, along with detailed installation procedures for top wall mounting and connection to Switch Car Kits. It also provides specific wiring instructions for Flowline controllers and outlines a maintenance procedure for cleaning the sensor to prevent jamming.
