Overview
ONICON F-2600 Series Inline Vortex Flow Meter for Water & Steam 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 to500° 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 that include serial communications and multiple analog outputs are also available.
