function-technical reasons (e.g. kind of liner in the measuring tube) lower limits may prevail.
10 Maintenance
The IFM 5080 K / i- EEx compact flowmeters are maintenance free with regard to flowmetering
properties. Within the scope of the periodic inspections required for electrical apparatus in
hazardous areas, it is recommended to check the flameproof enclosures for external damage and
signs of corrosion.
Opening of the housing of the primary head (coil housing) is not allowed, as this will nullify the
used type of protection for the explosion safety. There are also no serviceable parts inside the
primary head.
