The SUTO S 415 and S 418 thermal mass flowmeters offer gas flow and consumption measurement directly at the point of use. These highly economical units will help you improve system efficiency, while helping reduce compressed air usage and operating costs. Both versions come standard with wireless communication interface to help the user quickly and easily check the flow meter readings or adjust the settings via the SUTO flow meter app.
The S 415 is best suited to general process work where low cost and broad monitoring is required, while the S 418 is ideal for remote locations or high accuracy with its built in data logger and optional pressure sensing.
