Elesa® original design technopolymer plastic fluid column level indicators.
EN 650 version is highly resistant to shocks, solvents, oils with additives, aliphatic and aromatic hydrocarbons, petrol, naphtha, phosphoric esters.  Avoid contact with alcohol and detergents containing alcohol.
EN 650-AR version is for use with fluids containing alcohol.
/T models of both versions have incorporated thermometer.
Maximum continuous working temperature with oil: 190°F (90°C).
Direct contact between fluid and contrast screen is avoided preventing yellowing to screen; can be removed prior to installation to customize markings.
Entirely in transparent material, maximum fluid level visibility even from side positions, visibility magnified by lens effect.
Assembled using ultrasound welding to guarantee a perfect seal.
Upon request and in sufficient quantities, available in version for use in boiling water with set screws and nuts in AISI 303 stainless steel and O-rings in FKM.
Can be fitted either with a nut fixed on the inside of a reservoir (see drilling data) or from the outside by threading two holes on the reservoir. To endure best seal, apply the maximum torque on the bolts as indicated in the table.
