In coal mines, for rubber hoses and the measurement of calcium chloride, what type of flow meter should be used? An ultrasonic one? 、、、? ? ?
Electromagnetic, V-shaped cone. The quality is fine
For electromagnetic flowmeters, just pay attention to the right selection
Electromagnetic type, 4F/rubber lining; the grounding ring must be properly taken care of. If its accuracy becomes compromised after some time of use, it should be cleaned. For ultrasonic types as well, cleaning is necessary when scaling occurs in the tubes.
Electromagnetic type is the best option – it offers high precision. It features a PTFE lining and titanium electrodes; if there are many solid particles present, a ceramic lining can be installed. Additionally, a 316L grounding ring is required
Using an electromagnetic flowmeter is the best choice； Due to being rubber pipes or lined pipes, it may be difficult to use ultrasonic flowmeters for measurement.
