The Suto S421 compressed air Thermal Mass flow meter covers a wide measuring range. With the high resolution and sampling rate, a high-speed and precise measurement is achieved. The installation is done through the selected measuring section, with R-thread or with a flange connection. The sensors can save two calibration curves. Due to this, the sensor can be used in two different gases without any loss of accuracy. For example, S421 can measure the compressed airflow, but a the same time, S421 can use it in Nitrogen. The optional color display is designed to show all measured values like flow and total consumption. At the same time, You can use the display to manage the sensor settings like pipe diameter, gas type, or analog output scaling. The sensor offers two different signal output options. It can have an isolated analog and pulse output to read out the flow and the total consumption. Alternatively, you can use a MODBUS RTU interface to access all measured values via the digital interface.

According to your needs, various settings such as gas type, flow unit, reference standards can be set ex-factory. If it’s needed to change the settings on-site, you can use SUTO free S4C-FS mobile phone applications 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.

The S421 is the perfect meter to monitor your compressed air system and measure the compressed air flow and consumption.

  • Easy and affordable sensor solution to measure the compressed air flow and consumption
  • The sensor is calibrated in the measuring section, this allows a very high precision
  • Two calibration curves can be saved onto the sensor internal memory
  • Due to the two calibration curves, the sensor can be used with the highest precision in two different gases
  • Velocity, Flowrate, Consumption, and Temperature are displayed
  • IP65 protection class offers rugged protection in a rough industrial environment
  • Isolated analog and pulse outputs or MODBUS/RTU interface
  • Thermal mass flow measurement, pressure, and temperature independent
