Keller NanoLevel
BRAND: Keller America
Perfectly suited for pump control applications and monitoring levels in tanks, weirs, and cooling towers, the Nanolevel is compatible with any standard 2-wire, 4...20 mA current loop that supplies a minimum of 8 but no more than 28 VDC to the transmitter.
FeaturesStandard dual (4 - 20 mA & RS485) outputs simplify interface to controls, data collection, and telemetry systems.
Range: 0…4” and 0…120” W.C.
High accuracy and stability for very low ranges
Gold-plated ceramic sensing diaphragm. 16-bit internal digital error correction for cost effective low Total Error Band (TEB)3
316L SS housing construction.
2-year warranty covers defects in materials and workmanship.
User-rangeable analog output ensures compatibility as requirements change. Converter cable required, sold separately.
RS485 modified-MODBUS compatible interface allows up to 128 transmitters on a single bus.
Built in the U.S.A. ARRA Section 1605 Compliant.
Standard 3- 5 day lead time.

The Nanolevel submersible level transmitter utilizes a ceramic measuring cell for high resolution and excellent stability in applications with very low pressure ranges. The dual output feature ensures compatibility with most pump controllers and SCADA systems. The Nanolevel is assembled in the U.S. to customer specifications. Typical orders ship in 3 business days ARO.
Optional Accessories
Drying Tube Assembly - 900001.0002
Clear tube filled with indicating desiccant that attaches directly to cable vent tube to intercept water vapor. Highly recommended when operating in high humidity conditions. Must be periodically renewed as desiccant becomes saturated, turning color from blue (dry) to pink (saturated).
Bellows Assembly - 900001.0009
Alternative to the drying tube, this aneroid bellows attaches to cable vent tube and requires no periodic maintenance. Note that the use of the bellows results in a closed reference pressure system subject to zero shift errors induced by changing temperatures of up to 0.0004 psi/ºC. Not recommended for use with accuracy requirements of ±0.25% FS or better, or ranges < 2 psi.
Termination Enclosure - 900001.0034
Convenient option complementing gauge-type pressure/level transmitters where it is desired to terminate the transmitter cable close to the measurement point. It includes a NEMA 4X clear front enclosure (7.9 X 4.7 X 3.5 inches) with two, liquid-tight cable fittings (one in, one out), a terminal strip, and provisions for mounting both a drying tube or bellows assembly, each sold separately.
Cable Hanger - HU02216001
Single eye mesh cord grip style cable hanger for use with KELLER’s 0.230 inch O.D. cables, including PE, Hytrel, and Tefzel, used on Acculevel, Digilevel, Levelgage, LevelRat, Microlevel, and Nanolevel submersible level transmitters, and KELLER’s Valueline and Preciseline pressure transmitters.
Stabilizing Weight - 900001.0033
Zinc prop shaft anode adapted to fit Ø21 mm O.D. of Levelgage, Acculevel, and LevelRat submersible level transmitters. Aids in corrosion resistance as well as helps ensure that the cable remains taut in turbulent conditions.
