The By-Pass Level Indicator is installed outside of a vessel or tank. The liquid level in the tank can easly be observed from the change of the flag color. Optional devices of magnetic switch and level transducer can be added for electrical signa output and level transmitting.
PRINCIPLE
Fine-Tek's By-Pass indicator utizes hydrostalic prin-ciple to show the liquid level in the tank A foat with a magnet inside rises and drops according to the liquid level change. Magnetic fags will fip as foat passes through to indicate liquid level based on magnetic attraction method.
EF/MEF Series are by-pass level transmitter product lines, more commonly know as magnetic level gauge devices that can be equipped for local visual indication only or with level switches and an electronic level transmitter output. The magnetic level gauge units include their own self-contained chamber that would be mounted to the vessel, typically via side connections at the top and bottom areas of the EF/MEF by-pass chamber. The EF is standard size and MEF is a smaller “mini” version. These magnetic level gauge units are safer than glass gauges that they typically replace.
Description
The EF/MEF series are magnetic level gauge product lines capable of providing local visual indication, level switch activation and a continuous level transmitter output, all from a single device. They are by-pass style level transmitter devices typically mounted on the side of a vessel. The EF/MEF magnetic level gauge devices use the principles of buoyancy and magnetism. A float with a magnet inside resides in the by-pass chamber.
