Masoneilan 12400 Series Digital Level Transmitter

The Masoneilan 12400 Series is a 2‑wire, loop‑powered digital displacer‑type level transmitter/controller with HART communication, built on proven buoyancy and torque‑tube technology. It combines precise level measurement, local PID control, and optional level switch functions in one compact instrument, ideal for liquid level, interface, and density measurement in tanks, separators, and process vessels across refining, petrochemical, power, and oil & gas operations.
