Description

Intelligent and highly configurable. The LPU-2428 can calculate distance, level, flow, and volume in linear and non-linear tanks.

Programmable Intelligence
The LPU-2428 was made with intelligent software for highly configurable measurement. The sensor can calculate distance, level, flow, and volume. In addition, the sensor features a 32-point linearization table for non-linear tanks and channels.

Class 1, Div. 1
This loop powered sensor is suitable for use in hazardous areas rated CSA Class 1, Div. 1.

Maintenance-Free
With a tough, IP65-rated housing, its hazardous rating, and non-contact measurement, the LPU-2428 takes care of itself.

Common Applications

CI, D 1 Hazardous Locations
Open-channel Flow
Non-linear Tanks
Dam Tail-water Levels
Irrigation Channel Level or Flow
