The ONICON F-2600 Series Vortex Flow Meter is a ﬂexible design that provides accurate, reliable ﬂow measurement in steam and high temperature water applications. The F-2600 is designed with a two stage all welded bluff body/sensor design that enhances signal sensitivity and extends the operating range of the meter. This innovative feature also protects the sensors from pressure shocks and solids suspended
in the ﬂow stream.
The basic loop powered model provides volumetric ﬂow measurement for water at temperatures up to 500° F. Adding the integral temperature sensor option allows for mass ﬂow measurement of saturated steam. Meters provided with integral pressure and temperature sensors are capable of measuring mass ﬂow of superheated steam. Optional versions of the meter are also available that include serial communications and multiple analog outputs.
• Saturated steam
• Hot water to 500° F (260° C) standard 750° F (400° C) optional
Applications with optional pressure sensor
• Superheated steam to 500° F (260° C) standard 750° F (400° C) optional
