How to calibrate series pneumatic switch ball valve? (3) Inspection after installation
① Operate the driver to open and close the pneumatic ball valve for several times, which should be flexible without stagnation, to verify that it works normally.
② The design of connecting pipeline requires that the sealing performance of the flange joint surface between the pipeline and the spherical cavity should be checked
The structure of the electromagnetic flowmeter assumes that the magnetic field intensity B generated by the electromagnetic induction coil is constant, the induced voltage Ue generated is proportional to the fluid speed v, and the pipe cross-sectional area A is known, then the volume flow Qv can be calculated by the following formula:
