In particular, applications in which shock loads occur (for example, pulsed operation) should be discussed and checked in advance with our technical staff. The series DOZ03, DOZ05 and DOZ07 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. -
