OVERVIEW
What it does and why it is built this way
The LV-120 is an 80 GHz frequency-modulated radar. Its narrow beam passes close to tank walls and agitators and returns a clean echo even from low-dielectric liquids.
An encapsulated PTFE lens makes it immune to condensate, so it replaces ultrasonic and contacting sensors in corrosive vessels.
KEY FEATURES
3° beam angle for cluttered tanks
Reads through vapour, dust and temperature swings
Bluetooth commissioning from a phone
