Proper Usage The variable area flowmeters of the DS08 series are used exclusively for monitoring and indicating continuous flows of liquid media that do not attack the materials used. All other usage is regarded as being improper and outside the scope of the device. - Page 3 Do not use flow monitors with fast-switching valves. The series DS08 flow meter devices should not be deployed as the sole agents to prevent dangerous conditions occurring in plant or machinery. Machinery and plant need to be designed in such a manner that faulty conditions and malfunctions do not arise that could pose a safety risk for operators.

Page 16: Maintenance / Maintenance Plan
Maintenance / Maintenance plan Intervals for replacing wear parts DS08 type flow monitors require very little maintenance due to the small number of mov- ing parts. The intervals for the replacement of wear parts depend significantly on the oper - ating conditions as well as on the composition of the medium flowing through the device. - Page 17 Description: Viscosity compensation, mounting position and reliability: The flow meter and switch model DS08 works according to a The built-in spring and the magnetic float guarantee an abso- modified variable area principle.
