Description
The Keller Nanolevel is a submersible level transmitter for very low ranges, below 10 ft of water. Its gold-plated ceramic capacitive sensor stays stable on full-scale ranges as low as 4 in (about 100 mm) and up to 120 in (about 3 m), with ±0.1% FS static accuracy and a ±0.25% total error band (±0.05% / ±0.1% optional).
It suits pump control and level monitoring in shallow tanks, weirs and cooling towers, gives dual 4–20 mA and RS485 outputs, runs from any 8–28 V DC loop, and has a 316L stainless steel IP68 housing.
Argonmark Ltd supplies Keller 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.
