Description
The Keller LevelRat is a submersible level transmitter designed for wastewater, with a large non-fouling diaphragm that resists clogging and puncture in sewage, sludge and grease. It covers ranges from 0–5 ft (about 1.5 m) to 0–100 ft (about 30.5 m) of water with ±0.25% FS static accuracy and a ±0.5% FS total error band.
Outputs are 4–20 mA (UL/cUL intrinsically safe for Class I Div 1), 4–20 mA with RS485 Modbus, or 0–5/10 V with RS485. It is built in 316L stainless steel (titanium optional) to IP68, and lightning protection is included on 4–20 mA models.
Argonmark Ltd supplies Keller instruments across Bangladesh — Dhaka, Chattogram, Gazipur, Narayanganj and the gas fields, refineries, terminals and power plants beyond. Send us the model, range, process connection, output and any hazardous-area requirement, and we will confirm the right configuration, lead time and price.
