LevelRat Lift Station Water Level Transmitter
Non-fouling design for wastewater applications. Specifically designed for extended service in sewage lift station environments, the LevelRat by KELLER America features a wide sensing diaphragm yet small overall size. Unlike competing models which feature a fragile Teflon®-coated rubber diaphragm, the LevelRat incorporates a monolithic diaphragm which combines the non-stick quality of Teflon with superior toughness and abrasion resistance. Perfectly suited for pump control applications, the LevelRat is compatible with any standard 2-wire, 4...20 mA current loop, or 3-wire voltage systems.
Microlevel Microbore Submersible Level Transmitter
The Microlevel by KELLER America is the smallest diameter, media isolated submersible level transmitter in its class. At only 0.63”, it is specifically designed for applications that demand small size and high performance.
NSF 61 / NSF 372 approved construction for use in drinking water applications
User-rangeable analog output ensures compatibility as requirements change
Standard dual (analog & RS485) outputs simplify interface to controls, data collection, and telemetry systems.
ACCULEVEL High Accuracy Analog Submersible Level Transmitter
The Acculevel by KELLER America provides standard features that far exceed those of comparably priced transmitters, including standard ±0.25% FS or optional ±0.1% Total Error Band (TEB)3 accuracy. This level transmitter is approved to NSF 61 and NSF 3727 standards for water quality and includes KELLER America’s guaranteed lightning protection, making the Acculevel an outstanding value for liquid level measurement.
ACCULEVEL SDI-12 High Accuracy Digital Submersible Level Transmitter
The Acculevel SDI high accuracy level transmitter incorporates microprocessor-controlled signal conditioning to provide outstanding accuracy over temperature. Like the original Acculevel, it provides dual outputs but both are digital; one SDI-12 and one RS485. Both allow users to retrieve both level and temperature data and interface with a PC or exisitng SDI-12 logger and telemetry units.
LEVELGAGE General Purpose Submersible Level Transmitter
The Keller’s LEVELGAGE is a cost-effective solution to monitor and measure water level in a variety of applications including Industrial Control, Surface Water and Groundwater Monitoring. This water level transmitter features a 4 - 20 mA output and can be easily integrated to a process display controllers, data loggers, SCADA and PLC.
NANOLEVEL Submersible Ceramic Transmitter
The Nanolevel from KELLER is specifically designed for use in level measurement applications where full-scale ranges are less than 10 ft W.C. The Nanolevel’s ceramic capacitive sensor technology is proven to provide excellent stability in full-scale pressure ranges as low as 4 inches of water.
