AUTOFLOW was organized in 1982 to manufacture and market valves and instruments for the measurement control of process variables.

Micro Flow Switch


The FS6700 Series Micro Flow Switch is designed to precisely detect increasing or decreasing flow rate of liquids in critical processes. Typical applications include process analyzer sample conditioning systems, pump coolant and lubrication monitoring and chemical injection. The linear, high resolution adjustment allows for precise settings. The miniature compact construction is ideal for high density system packaging. (also available in a liquid version)

MicroFlow Switch with ISA SP-76 Mount for Modular Sample Systems

• 316L Stainless Steel
• North America Standards Class I, Div 1
• European Standards EExdII CT3
• CE Compliant
• Adjustable Flow Ranges 30 sccm to 20 slpm

Flow Switch - High Flow


The FS5100 Series Flow Switch – High Flow is designed to precisely detect increasing or decreasing flow rate of gases for critical processes. The electrical switch is operated by a high energy permanent magnet. The permanent magnet is totally encapsulated by 316 stainless steel, utilizing the patented Autoseal process, providing a continuous, impenetrable barrier of 316 stainless steel, which is chemically resistant to even the most aggressive chemical action. The linear, high resolution adjustment allows for precise settings. The compact construction is ideal for high density system packaging.

Priority Flow Switch High Flow Very Low Differential Pressure


The FS5900 Series Flow Switch uses a special priority channel to virtually eliminate differential pressure under high flow conditions, while providing the most reliable flow fault monitor at low flow rate set points. In a typical application example, it would be possible to set the low flow alarm set point at say 1 slpm, with a purge flow rate of 100 slpm or higher.
