The Acculevel high accuracy level transmitter incorporates advanced microprocessor-controlled signal conditioning to deliver exceptional accuracy across various temperatures. It features dual outputs, including both analog (current or voltage) and digital RS485 options, offering users the ability to retrieve level and temperature data, interface with a PC, and recalibrate the analog output within a range of 10% to 110% of the basic range (requires converter cable and KELLER software).
This outstanding instrument has achieved certification to NSF/ANSI 61 and 372 standards, making it suitable for use in drinking water applications. Moreover, models equipped with 4...20mA analog output come with guaranteed lightning protection at no extra cost, accompanied by a lifetime warranty against voltage surge damage.
The Acculevel is designed and constructed in the U.S. based on customer specifications, which can include custom pressure ranges and cable lengths. Additionally, swift order processing ensures that most orders ship in 3 - 5 business days or less.

Optional Accessories for Keller Pressure Transducers
Drying Tube Assembly PN
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
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
Pressure Test Adapters
These custom built assemblies are designed to facilitate calibration and maintenance testing. Versions are available to connect the Acculevel, Levelgage, LevelRat, and Microlevel to a pressure calibrator.
Cable Hanger
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
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.
