AutomationDirect adds ProSense Vibration Fork Liquid Level Switches

ProSense® VFL Series Vibration Fork Level Switches from AutomationDirect are designed using tuning fork technology for reliable liquid point level detection for monitoring, alarming, and control applications.

The switch tuning forks vibrate at their natural frequency. When the forks contact a liquid, the fork vibration frequency changes and triggers the switch output.


Suitable for use in tanks, vessels, and pipes, the VFL series is an ideal alternative for applications where other liquid point level technologies such as float switches or conductive, optical and capacitance sensors are not suitable due to conductivity, turbulence, buildup, air bubbles, foam, pressure, temperature, and viscosity changes.


ProSense VFL series switches are offered in two process connection sizes with short and extended insertion lengths, standard and high temperature constructions, and a 3-wire DC switch output for connection to controller inputs or a 2-wire AC/DC switch for control of valves and pumps. Fork Level Switches start at $137.00
