E4 Modulevel® Liquid Level Displacer Transmitter DESCRIPTION The E4 Modulevel® is a loop powered, two-wire instrument, utilizing simple buoyancy principles to detect and convert liquid level changes into a stable output signal. The linkage between the level sensing element and output electronics provides a purely mechanical design and construction. The vertical in-line design of the transmitter results in low instrument weight and simplified installation. The instrument comes in a variety of configurations and pressure ratings for varied applications. The E4 Modulevel has microprocessor-based electronics with 4–20 mA/HART® digital output. E4 supports the FDT/DTM standard and a PACTware™ PC software package allows for additional configuration, diagnostics, and trending capabilities. TECHNOLOGY Changing buoyancy forces caused by liquid level change act upon the spring supported displacer causing vertical motion of the core within a linear variable differential transformer. As the core position changes with liquid level, voltages are induced across the secondary windings of the LVDT. These signals are processed in the electronic circuitry and converted to a useable output signal. The enclosing tube acts as a static isolation barrier between the LVDT and the process media. APPLICATIONS MEDIA: Liquids or slurries, clean or dirty, light hydrocarbons to heavy acids (SG=0.23 to 2.20) VESSELS: Process & storage, bridles, bypass chambers, interface, sumps & pits up to unit pressure & temperature ratings. CONDITIONS: Most liquid level measurement and control applications including those with varying dielectric, vapors, turbulence, foam, buildup, bubbling or boiling and high fill/empty rates; liquid/liquid interface level measurement or density cont

• Range Spring/LVDT design yields performance benefits over traditional torque tube displacer transmitters E4 Modulevel is capable of tracking the interface level of two immiscible liquids with different densities. Each unit is custom-made with a displacer specially designed for the user’s application. This allows it to detect the position of a clean interface or an emulsion layer and convert it into a stable 4–20 mA signal. Contact the factory for assistance in specifying an E4 for interface service. Note that for proper interface detection, the entire displacer must always be immersed in liquid....
