Description
The APG LPU-2428 is an intrinsically safe, two-wire ultrasonic level transmitter approved for Class I Div 1 and Zone 0 locations. It measures liquids from 0.3 to 7.6 m and solids up to 3 m with ±0.25% accuracy, and can convert level into volume for common tank shapes or into open channel flow and totals for weirs and flumes.
A 32-point linearization table covers unusual vessels. It is configured through a USB module connected across the loop, mounts with a 2 in NPT thread and is rated IP65.
Argonmark Ltd supplies APG instruments across Bangladesh — Dhaka, Chattogram, Gazipur, Narayanganj and the gas fields, refineries, terminals and power plants beyond. Send us the model, range, process connection, output and any hazardous-area requirement, and we will confirm the right configuration, lead time and price.
