  • Standard dual (4 - 20 mA & RS485) outputs simplify interface to controls, data collection, and telemetry systems, PLC and SCADA Systems.

  • Standard Accuracy: ±0.25% FS Optional Accuracy: ±0.1% FS

  • Lightning protection included with all 4-20 mA models

  • 16-bit internal digital error correction for cost-effective low Total Error Band (TEB)3

  • 316L stainless construction (standard) - Optional Titanium for severe applications.

  • 2-Year warranty covers defects in materials and workmanship.

  • User-rangeable analog output ensures compatibility as requirements change.

  • RS485 modified-MODBUS compatible interface allows up to 128 transmitters on a single bus.

  • Built-in the U.S.A. ARRA Section 1605 Compliant.

The Acculevel is suitable for:

  • Drinking water and potable water systems

  • Groundwater and well-level monitoring

  • Municipal water storage tanks

  • Reservoir and surface-water monitoring

  • Rivers, streams, and watershed studies

  • Stormwater monitoring

  • Environmental and hydrological applications

  • Industrial tank-level measurement

  • Integration with PLC, SCADA, telemetry, and data-logging systems

Typically ships in 3–5 business days. Contact our sales team today to place an order or request a quote.

Optional Accessories for Keller Pressure Transducers

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

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.

Sour Gas Trap

Effectively prevents any H2 S vapor from migrating down the atmospheric vent of the level transmitter, on account of its ability to absorb and trap any such vapors which enter it. The Sour Gas Trap is intended to be installed either stand-alone or in tandem with a KELLER America Drying Tube.

This submersible pressure transducer is ideal for water level monitoring in environmental, municipal, and industrial applications. Designed for accuracy, durability, and easy integration with control systems, it is a trusted solution for continuous level measurement.
