FLT93C Thermal Flow Switch Helps Clean Up

By Bhalchandra Chorghade, Editor, CNCTimes.com

Engineers responsible for maintaining a sanitary environment in pharmaceutical, biotechnology and food/beverage plants will find that the FLT93C Flow Switch from Fluid Components International (FCI) provides accurate liquid flow rate measurement for clean in place (CIP) system operational integrity.

The sanitary FLT93C Thermal Flow Switch, with its stainless steel wetted materials and standard 20Ra finish, available in either mechanical polish or electro-polish finishing, supports both skid-mount and stationary clean-in-place (CIP) systems. The purpose of these important systems is to ensure all the process piping and equipment is thoroughly cleaned per ASME BPE standards to avoid contamination.

Monitoring the process cleaning solution’s minimum liquid flow rate with the FLT93C Thermal Flow Switch ensures the flow of liquid fluid is maintained during the entire cleaning process runtime. This switch operates over a wide flow range of 0.01 to 3.0 fps (0.003 to 0.9 mps), and it also offers excellent accuracy of ± 0.5% reading or ± 0.04 fps (± 0.012 mps).

Relying on its unique temperature compensation technology, the FLT93C Flow Switch is the industry’s only thermal switch that ensures set point accuracy for process temperatures that can vary up to ±100°F (37.8°C). The FLT93C is easily field-configured or factory preset, providing unparalleled flexibility, accuracy and stability for all multiple process sensing and switching requirements.

Suitable for 0.7 to 4-inch (19.05 to 101.6 mm) sanitary tubing process lines, the FLT93C Flow Switch connects with a secure tri-clamp fitting for easy removal for inspection and servicing. The 316L stainless steel wetted materials are available in both mechanical polish (SF0 to SF3) and electro-polish (SF5 and SF6) surface finishes with 20 Ra maximum (µin) finish; 10 Ra maximum (µin) electro-polish finish (SF 4) is available upon request. The FLT93C construction complies with ASME BPE requirements.

Beyond its application in CIP systems, other pharmaceutical uses of the FLT93C Flow Switch include compendial water systems (WFI, PW and HPW) and solution preparation systems (buffer solution). Special options are available for applications requiring more corrosion resistant, wetted materials such as Hastelloy C and Class 1, Div 1 and 2 hazardous areas.
