The SUTO S421 Inline Thermal Mass Flow Sensor provides reliable compressed air and gas flow and consumption monitoring in main and header lines with a wide measuring range. With the high resolution and sampling rate, a fast and precise measurement is achieved. Easy Installation and Optional Display The installation is done through a measuring section with a pre-defined diameter, with R-thread or with flange connections. The flow sensor comes calibrated on the selected measuring section. The optional color display is designed to show all measured values like flow and total consumption on the screen. The display can also be used to manage the sensor settings, like gas types, output signal settings or reference conditions. Measurement of two gases at the same time The thermal mass flow sensor can save two calibration curves, this means the sensor can be used in two different gases without any loss of accuracy. This would allow for example compressed air flow to be measured and have the ability to switch to measure Nitrogen by simply changing the gas type via the S4C-FS app or using the sensors display. Various Sensor Outputs The S421 Thermal Mass Flow Sensor offers 4 different signal output options. It can have an isolated analog and pulse output to read out the flow and the total consumption. The Modbus/RTU and Modbus/TCP output options offers a state-of-the-art digital interface solution to connect the meter to high level controllers or software solutions. By using M-Bus as an output, the meter can be connected to existing metering networks easily.
