Keller Nanolevel Submersible Level Transmitter Video Intro

Keller Nanolevel is a cost-effective submersible level transmitter built around a ceramic capacitive sensing cell, designed for long-term stable measurement in shallow water and wet wells. At very low full scales of just 4 inches of water column (4 inWC) — where ordinary sensors drift from heat dissipation — the Nanolevel holds static accuracy at ±0.1% FS (optional ±0.05%). It offers dual 4-20mA and RS485 outputs that drop straight into pump controllers and SCADA without extra converters, running on 8-28 VDC. The ceramic cell stays stable with no wet drift even down to 4 inWC, giving a long service life. It is widely used in tanks, weirs, cooling towers and pump-control systems to prevent overflow and dry-run downtime and losses.
