Heavy-duty flowmeter regulators and flowmeters
1 Rugged aluminum protective housing
Heavy-duty flowmeter regulators and flowmeters feature an exclusive self-centering ball guide which
protects flow tubes from damage while
provides accurate readings even if tipped. This ensures optimum weld quality and gas savings. Others use offering unobstructed view of flow reading.
