Liquid flow meter
Thread Content
Are there any flow meters that can only measure liquid flow? When there is no liquid in the pipeline and only gas passes through the flow meter, the meter should not give any readings, unaffected by the gas.
That’s exactly how electromagnetic flowmeters work.
An electromagnetic flowmeter will do. Let’s see if the liquid conducts electricity
For conductive liquids, an electromagnetic flowmeter can be used
An electromagnetic flowmeter is a suitable choice; it’s sufficient to check whether there is conductivity. If no liquid is flowing, an empty pipe alarm will be triggered, and no measurement values will be available
Both electromagnetic flowmeters and ultrasonic flowmeters will work, right?
An electromagnetic flowmeter is used to measure liquids, not gases
Since the medium does not conduct electricity, ultrasound can be considered
