Magnetic level gauge Data Sheet DS-MLG-810-eng June, 2008 Page 2 Type 810 General The magnetic level gauge type 810 allows to measure directly liquid levels, even corrosive or dangerous, into vessels or under pressurized tanks. The design of this equipment ensures a good accuracy, an excellent reliability and a safe use. A float equipped with a permanent magnet follows the level variation of the liquid to be measured. Slider version: the float drives a magnetic slider which slides into a pyrex tube mounted on a graduated scale. Wafers/rollers version: the float reverses magnetically locked bi-coloured Rollers. The red zone indicates the level of liquid in the tank Slider version Rollers version Design TOP of the instrument Caps + options Chamber / Body Tubular pressurized chamber, fitted with flanges and connections to be installed on customer's tank. This main part of the instrument is filled by the fluid to be measured. It is identically stressed (pressure, temperature, corosiveness…) than the main storage vessel on which it is connected. All welded parts are TIG welded. CC dimension The "Center- to- center" dimension. This area represents the mesuring zone thanks to the reading system and the float movement. It is located right between both side-side connections. BOTTOM Flange In order to allow the float to be inserted into the chamber Options on request on bottom flange Measuring zone: This area is composed of the reading system and options on request (contacts, alarm, reading scales…) This area is entirely travelled by the float. Float: Hermetically Sealed item designed in accordance with the rating of the chamber and the process medium. It follows the variations of level of liquid. It carries the magnets to communicate with the reading system.
