Omega FT-50 Series flow switch fitting is designed to be used with the Omega Engineering Thermal Dispersion liquid flow switch (FST-200 series). When combined, they create a cost-effective and precise method of sensing flow for liquids ranging from 0.4 to 1.2 SG and viscosities of 1 to 300 cp. The FT-50 Series is also capable of monitoring pulsating flows from 10 to 100 pulses per minute, thanks to its unique design that creates a vortex inside its chamber. This vortex utilizes its stored energy to generate a flow pattern, making it ideal for low flow conditions and pulsating flows.
