Flow meter designed for application in highly inflammable fluids. The aluminium (Alu) or stainless steel (SS) meter works on oval gear principle and used for flammable mineral oil products, easily flammable hydrocarbons and other chemicals in explosion hazardous area. It operates in high flow rates, temperatures and operating pressures.

The meter is suitable for thin-bodied and highly viscous liquids with flow rates from 6 l/min to 120 l/min.Meter displays high accurate partial and total volume with low friction losses. The explosion proof body is in compliance with ATEX Directive 94/9/EC, category 2. Meter comes in HDO 250 type Ex Alu for neutral, easily inflammable liquid and type HDO 250 Ex SS for neutral and aggressive, easily inflammable liquid
