Process Instrumentation

Siemens Milltronics Process Instruments Inc. (SMPI) designs and manufactures level measurement tools for use in mining, food, chemical processing, oil & gas, water & wastewater, cement, and dry bulk storage. SMPI is committed to environmental management and became ISO 14001 certified in 2008.[1]

SMPI was founded on June 21, 1954 as Milltronics Ltd. by Dave Weston and was later acquired by Siemens in 2000. Its breakthrough was in the late 1970s when it pioneered ultrasonic level measurement. In 1984 Milltronics became the first manufacturer of microprocessor-based ultrasonics instruments with the AiRanger IV.

  • Level

    Constant product quality, plant safety and economic efficiency - these are important aspects for any level measuring point. 

    Levels in liquids, pastes, bulk solids or liquefied gases are often measured in tanks, silos or movable containers. For continuous, interface and density measurement as well as for point level detection a broad range of measuring principles is available. Endress+Hauser supports you from planning through commissioning and also maintenance of your measuring point.
