3.3.3 Gasket Size(customer pipe)
WARNING
All gaskets used for piping of Magnetic Flowmeters should be prepared by customers except in some cases.
Be sure to choose a gasket with an inner and outer diameter that does not protrude inside the piping.
If the inner diameter of the gasket is too large, or outer diameter of the gasket is too small, uid leakage may result.
