Digital E3 Modulevel Liquid Level Displacer Transmitter is an advanced, intrinsically safe two-wire instrument utilizing simple buoyancy principle to detect and convert liquid level changes into a stable output signal. The linkage between the level sensing element and output electronics provides a simple mechanical design and construction. The vertical in-line design of the transmitter results in low instrument weight and simplified installation. The instrument comes in avariety of configurations and pressure ratings for varied applications.The Digital E3 Modulevel has microprocessor-based electronics with 4–20 mA/HART® or FOUNDATION fieldbus™ output. E3 supports the FDT/DTM standard and a PACTware™ PC software package allows for additional configuration and trending capabilities.
