7750 Series - Stainless Steel Tube Flowmeter

These 316L Stainless Steel meters feature flange connections, all welded construction (no elastomers),
and an end to end length of 250mm. A float and tapered tube design provides longer, more linear scales.
A 4-20mA transmitter option adds to its versatility.
