ISO-9001:2000 certified EF Series By-Pass Liquid Level Gauge More than just another level measurement company … Aplus Finetek Sensor, Inc. PRODUCT INTRODUCTION OPERATING PRINCIPLE The EF Series is a liquid level gauge that is installed on the outside of a tank or other vessel. The EF can provide any combination of a local visual indication of liquid level, single or multiple level switch output and a continuous level transmitter output. The EF series by-pass liquid level gauge utilizes hydrostatic buoyancy principles to indicate liquid level. A float with a built- in fixed magnet inside travels up and down inside the by-pass chamber according to the changing level inside the tank. A visual flag indicator is attached to the chamber to provide local visual indication of the liquid level inside the tank. Each individual flag has two colors, one on each side, and a magnetic element. The magnetic flags will flip as the float inside the chamber passes by each flag going up or down and indicates the liquid level. Several switch types are available that are magnetically actuated. These switches can be mounted attached to the outside of the chamber at the desired switch activation point. As the magnetic element inside the float passes by the level switch, the built-in reed switch will change state. Level transducers can also be attached to the outside of the EF chamber and will provide analog and/or digital outputs. The EF series by-pass liquid level gauge can provide the functionality of a local visual indicator, a level switch and a level transmitter all in a single device. These optional accessories and example assemblies of the EF series are illustrated here on pages 9 and 10. Flag By-pass Chamber Magnet Float FEATURES • Mounts external to tank, thereby avoiding any obstructions inside the vessel. • Easily equipped to provide multiple functions, i.e. local visual indicator, level switches and level transmitter. • Can provide local visual indication without any power supply. • Choice of flag indicator colors available; Red/White or Green/White • Plastic or metal chambers, blanketed or jacketed chamber, heated chamber, coated chamber and high pressure (1,445psi/100bar) chamber available. • Side and top mounting available • Wide range of process connections, tops, bottoms and accessories.
