The OPTIMUS series offer a solution to measuring low pressures where a flange is required. By welding the diaphragm across the entire wetted parts, a substantial increase in diaphragm diameter can be achieved without a parallel increase in flange size. Displacement is increased accordingly which in turn improves accuracy at low pressures.

The OPTIMUS can be fitted with a number ASME and EN standard flanges, making it a versatile seal for use in a wide variety of situations. It is also available with a threaded connection. The upper part can be dismounted for washing the internal part of the chemical seal.
