Indicating transmitters and indicating controllers with transmitters are also available as well as indicating controllers. The controllers are available either in a local type to set the set-point value manually with a knob on the instrument or in a cascade type (remote type) to set the setpoint value with a pneumatic set-point signal. Model KFLB Liquid Level Indicating Controllers are displacement type instruments for the measurement and control of such process variables as liquid levels, boundary surfaces, and specific gravities. FEATURES . A wide variety of elements materials and control mechanisms are available to meet various applications. . The unit has a pneumatic circuit board and a sturdy, heat-resistant weatherproof case, thereby greatly improving durability and reliability. . The pneumatic circuit board system allows the user to readily add or eliminate control mechanisms and units, thereby enhancing system modification and expansion flexibility. . Interchangeable parts are used to the maximum practical extent, thereby reducing the number of spare parts to be kept in stock. . Able to cover wide ranges of temperatures, pressure, and specific gravities. APPLICATIONS . To a level measurement of the reaction, the distillation, the drying and the recovery unit. . Boundary surfaces and specific gravity measurement. . To the measurement in the cryogenic services (liquefied gas etc. of min. -196°C) and high temperature (max. +400°C) services. . To the measurement in high vacuum (min. - 101.3 kPa) and high pressure (max. 15 MPa) services. 6 5 Specifications are subject to change without notice. “This product is designed for general industrial use.”
