The flow-dependent verticalposition of the float in the measuring tubeis transmitted by a magnetic couplingsystem to the scale in the indicator flowmeter is installed in a vertical piperun, with flow from bottom to top.

3 Owing toits rugged design, the H 250 variable -areaflowmeter is particularly suitable for difficult applications and the M9 indicator,the vertical position of the float is transmitted to the pointer/magnet system, and the flow valueindicated directly on the 250 Electromagnetic compatibility (EMC)The Variable-area flowmetertype: H 250/M9 /ESK IImeets the requirements of the 89/336/EEC directivein compliance with the following European standards:EN 61326 : 03/1997+A1 : 04/1998+A2 : 03/2001and also the requirements of NAMUR recommendation NE 21/05 (Ex) versionThe Variable-area flowmeter H 250 M9 is approved for use inhazardous Bundesanstalt:EEx ia and EEx ib 250/M9 : PTB 01 ATEX 2181 Factory Mutual Research (FM) USA:Class I, Division 1, Groups A, B, C and DClass I, Division 2, Groups A, B, C and Standards Association (CSA)Class I, Division 1, Groups A, B, C and DClass I, Division 2, Groups A, B, C and DLR 105802-7 Indicator M9 of modular construction A module rack in the M9 indicator accommodates all electrical add-on functions and the scale plate.

4 The modules of electrical options ESK II, ESK3-PA, ESK-Z,K1 or K2 and the scale plate are plugged into the module rack (plug-in technique). Module replacement or retrofitting without interrupting the processand without dismantling the pointer. If process temperatures should exceed the max. allowable level for thestandard version, the indicator can be adapted to the new operatingconditions by way of an adapter (HT version). Measuring sections made of various materials and with different linersare available for the process products.
