The Keller Microlevel submersible level transmitter has the smallest diameter in its class. At only 0.63", it is specifically designed for applications that demand small size and high performance. The Microlevel combines piezoresistive silicon sensor technology with Keller's state-of-the-art signal conditioning circuitry to make a very reliable transmitter with excellent Total Error Band (TEB) accuracy over a wide compensated temperature range. Standard dual outputs simplify interface to controls, data collection, and telemetry systems.

The ability of the Microlevel to achieve this performance day after day, across varied operating conditions, makes it the ideal solution for ground water level measurement and environmental monitoring applications. The user-rangeable analog output ensures compatibility as requirements change and the RS485 modified-MODBUS compatible inteface allows up to 128 transmitters on a single bus.
