Page 4: Operating Principle
The medium flows from below through a glass measuring cone that gets wider on top. Thus, the float is raised and indicates the respective flow rate on the scale provided on the measuring cone. To monitor flow rate limits, the URM meters can be optionally furnished with “open collector“ proximity switches. -
Page 5: Electrical Connection
Slide the switch housing up or down until the reference edge coincides with the desired switch-point scale reading. Overranging With non-pulsating flow, the maximum flow rate can be exceeded. Only an increase in pressure loss will result (max. permissible operating pressure must not be exceeded!) URM K05/0522 page 5... -
Page 6: Maintenance
9. Maintenance If the medium to be measured is clean, the series URM is virtually maintenance- free. If deposits form on the inner housing or parts, periodic cleaning of the unit is recommended. Remove the units from the piping with a suitable tool; clean the flow meter with a suitable cleaning agent or make use of an ultrasonic bath. -
