King Instrument 7710 Series Rotameter

The stainless steel King Instrument 7710 series rotameter utilizes a float and tapered tube design. As a result, the 7710 series rotameters have a longer and more linear scales as well as better pointer stability and 40% greater accuracy than competitively priced products.

The King Instrument 7710 series rotameter is housed in 316L Stainless Steel. Complete with a 120mm scale, the 7710 series rotameter can be used in high pressure systems up to 1500psi and high temperature applications up to 350°F.

Options Available to the King Instrument 7710 Series Rotameter
Additional flange connections
Additional O-ring materials for chemical compatibility or higher temperatures: Maximum temperature of EPR: 225°F (107°C)
Maximum temperature of Buna-N: 275°F (135°C)
