Description
The Keller Microlevel is a submersible level transmitter only 16 mm (0.63 in) in diameter, made for small wells, piezometers and other tight spaces. Its piezoresistive sensor with digital error correction gives ±0.1% FS static accuracy and a ±0.25% total error band, over any range from 0–3 ft (about 0.9 m) to 0–900 ft (about 274 m) of water.
It has dual 4–20 mA and RS485 outputs, runs on 10–30 V DC, includes lightning protection, and is built in 316L stainless steel to IP68 with NSF/ANSI 61 and 372 approval for drinking water.
