Genesis Models ED1 & ED2 High Performance Multiphase Detector DESCRIPTION The Genesis Multiphase Detector is a Time Domain Reflectometry (TDR)-based, 24 VDC level detector designed to accurately measure the various layers in interface level measurement applications. Encompassing a number of significant engineering accomplishments, this leading edge level detector is designed to provide measurement performance beyond that of many of the more traditional technologies. Utilizing patented "Top-Down" and "Bottom-Up" signals, along with advanced level detection algorithms, this single device can be used in a wide variety of interface applications ranging from very light hydrocarbons to water-based media. This detector, like other Magnetrol devices, is designed to maximize ease of wiring, configuration, and viewing of the versatile graphic LCD display. The Genesis supports both the Field Device Integration (FDI) and Enhanced DD (EDDL) standards, which allow viewing of valuable configuration and diagnostic information in tools such as PACTware ™, AMS Device Manager, and various HART ® Field Communicators. APPLICATIONS MEDIA: Hydrocarbons to water-based media (Dielectric Constant εr = 1.4–100) VESSELS: Most process, separator, or storage applications up to rated probe temperature and pressure. CONDITIONS: All interface measurement and control applications including those with thick/dynamic emulsion layers, process conditions exhibiting, foam, surface agitation, high fill/empty rates, and varying dielectric media or specific gravity. Measures Multiple Phases within Interface Applicati

The top-down signal provides a clear view of the oil layer. The bottom-up signal provides a clear view of the water level. One transmitting for the bottom-up measurement. The coaxial probe is the most efficient of all TDR probe configurations and should be the first consideration in all applications. Analogous to the efficiency of coaxial cable, a coaxial probe allows almost unimpeded movement of the high frequency pulses throughout its length. The electromagnetic field that...
Open the catalog to page 3The standard coaxial offering for the Genesis is an Enlarged diameter probe that can be generally used for most clean applications. Coaxial Probe Signal Propagation With a PFA coated active center rod surrounded by four (4) reference rods, the 5-conductor Pentarod probe is an alternative probe offering for the Genesis. Although this probe still yields excellent performance, its open design makes it less susceptible to buildup and bridging. Both of the probes offered with the Genesis are unique, and each has specific strengths and weaknesses. While there can be overlap, and both probes can...
