The series DS09 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 3: Functional Description
Qualified Personnel The DS09 devices may only be installed by trained, qualified personnel who are able to mount the devices correctly. Qualified personnel are persons, who are familiar with assembling, installation, placing in service and operating these devices and who are suitably trained and qualified. -

Keep a space of minimum 100mm to those materials (e.g. steel). Ensure that there are no foreign particles in the device • Ensure that the device is not soiled • Do not use any medium containing solids • DS09 Instruction manual 05/2018 page 4... - Page 5 – Never reduce the pipe diameter immediately before the device Unimpeded flow sections An unimpeded flow section of 10xDN (rated width) must be maintained before the device. An unimpeded flow section of 5xDN (rated width) must be maintained after the device. DS09 Instruction manual 05/2018 page 5...
- Page 6 If the pipe system ends at an unimpeded outlet, the flow monitor must not be installed directly in front of the opening. The device must always be completely filled with media to ensure measuring accuracy. DS09 Instruction manual 05/2018 page 6...
