Levelrat, Non-Fouling Submersible Level Transmitter

The LevelRat non-fouling submersible level transmitter is specifically designed for use in environments that would clog a traditional level transmitter such as lift stations. The unique diaphragm combines increased durability and Teflon-like non-stick properties to provide increased service time without maintenance. Additionally, the small profile minimizes accumulated solids, while simplifying installation.

Description

Keller level transmitters provide an infinite combination of level ranges, output options, and cable lengths, which ensures the perfect fit for monitoring equipment. They are frequently paired with a SCADA, PLC, or compatible display / control system for use as a water level indicator or controller.

KELLER submersible level transmitters offer high accuracy down to 900 feet with built in lifetime lightning protection and standard three day shipping. Known for their superior reliability, reasonable cost, and ready availability, Keller submersible level transmitters feature small size and integral signal conditioning; simplifying installation anywhere quality liquid level sensors are needed.

Non-Fouling Submersible Level Transmitter for Lift Stations and 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.

The LevelRat utilizes proven piezoresistive silicon measurement technology combined with KELLER’s state-of-the-art, microprocessor-based signal conditioning circuitry to provide outstanding accuracy and reliability over a wide compensated temperature range.

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. The RS485 interface allows users to scale the analog output to any desired range within the standard pressure range. The LevelRat is typically suspended into the liquid by a standard PE-jacketed cable that is both self-supporting and vented. Optional Hytrel or Tefzel-jacketed cables are available, should the installation require greater protection against chemical interaction.

Features

KELLER America’s guaranteed lightning protection makes this transmitter ideal for installation in areas prone to chronic damage due to transients caused by lightning. Models equipped with 4…20mA analog output include guaranteed lightning protection at no additional cost. This feature protects the Levelgage from fast-rising transients and carries a lifetime guarantee against damage from electrical surge.
