Instructions. In compliance with European Directive 94/9 EG (ATEX 100a), variable-area flowmeters of the H../../M10-EEx series are certified in conformity with European Standards EN 50xxx for use in hazardous areas under PTB 01 ATEX 1154 by the Physikalisch-Technische Bundesanstalt (PTB).
Process products Flammable products are allowed provided they are not present in potentially explosive form. Category / Zone allocation The H../../M10-EEx variable-area flowmeter is basically designed in Category 2 for use in Zone 1. Type of protection The H../../M10-EEx variable-area flowmeters bear the following marking: EEx d IIC T6 Special lock The sealing covers of the electronics compartment are secured by a special lock.
Protection IP67 and each be separately certified in conformity with EN 50 018. Any requirements specified in the test certificates of the components shall be observed. Power supply Type H../../M10-EEx variable-area flowmeters do not require any separate power source. The necessary supply is obtained via the current output. I/O functions When connecting the I/O interfaces of the H../../M10-EEx variable-area flowmeters, the...
Section 3.2 (Categories / Zone allocation), Section 2 (Type code) and Section 4 (Marking). When installing, please pay special attention to the following points. Signal converter M10-EEx d – Supplementary instructions 11/2002...
5.1.1 General Insulation rating The insulation of variable-area flowmeters H../../M10 - EEx is rated in conformity with VDE 0110-1/04.97, equivalent to IEC 60 664-1, and takes into account the following ratings: • Overvoltage category for signalling and measurement circuits: II •...

⊥ Note the electrical data of the circuits given in Section 3.7! Even when operated in the non- hazardous area, the requirements pertaining to the signal output circuits need to be met. Signal converter M10-EEx d – Supplementary instructions 11/2002...
• Inspection of the housing, cable entries and incoming cables for signs of corrosion and damage, • Check of pipe connections for leakages. Signal converter M10-EEx d – Supplementary instructions 11/2002...
Please refer to Sections 8.2.1 and 8.2.2. In addition, make sure that all process connections and the pipeline are non-pressurized and free of product. In the case of environmentally critical substances, carefully decontaminate the wetted parts of the flange system after dismantling. Signal converter M10-EEx d – Supplementary instructions 11/2002...

(15) Device description The H…./…./M10-EEx variable-area flowmeter is designed to measure the volume rate of flow of flammable and non-flammable gases and liquids in vertical pipe runs. The flow through the measuring tube is from bottom to top, and the guided float adjusts so that lifting force, form resistance and float weight are in equilibrium.
