SUTO S401 Thermal Mass Flow Meter

compressed air Thermal Mass flow meter, as the Suto iTec S401, is needed in almost any compressed air system. It helps you to monitor your compressed air system and in the end, it helps you to optimize your system and to save costs.
The Suto S401 compressed air flow meter is easy to use, affordable, and offers a wide measurement range. This makes it easy for you to choose the right flow meter, the S401 which fits your needs. The S401 is a thermal mass flow meter, based on its measurement principle it’s not required to compensate for the compressed air pressure and temperature, so you do not need any additional measurement installations to measure the flow and the consumption.
Due to the thermal mass flow, the flow meter is also well suited to be used in any other gas like Nitrogen or many other technical gases. The S401 sensor technology offers you a high resolution and a high sampling rate, resulting in a very fast and precise measurement. The flow meter can save two calibration curves; due to this, the sensor can be used in two different gases without any loss of accuracy.

The optional color display is designed to show all measured values like actual flow and total consumption. At the same time, the display can be used to manage the sensor settings like pipe diameter, gas type, or output settings.
The S401 flow meter offers two different signal output options. It cant be equipped with an isolated analog and pulse output to read out the compressed air flow and the total compressed air consumption. Alternatively, a MODBUS RTU interface can be used to access all measured values via the digital interface.
Since the flow meter can be easily installed through a standard ball valve, it can be easily removed for calibration without shutting down your compressed air system.

According to your needs, various settings such as gas type, flow unit, and reference standards can be set ex-factory. If needed to change the settings on-site, you can use Suto free S4C-FS mobile phone application for android phones. This enables you to change the settings wirelessly on-site, within the touch of your smartphone. Managing your compressed air was never easier. This all makes the Suto S401 compressed air flow meter the best-suited sensor for your application.
