An electromagnetic flowmeter includes a measuring tube through which a fluid to be measured flows, electrodes which detect an electromotive force generated by a magnetic field applied to the fluid. The end dividers may be secured to a header frame such that the end dividers float over uneven terrain. The sole has slip resistance properties due to the material from which it is made and the texture of its outer surface. The inventive golf training device may also be referred to as a lag rag or as a wind speed resistance trainer.
