S421, inline type flow sensor, 4 MPa version

The S421 flow meter is designed to measure compressed air in a user-friendly and affordable way. The S401 is a thermal mass flow meter, so it is not necessary to set the compressed air pressure and temperature separately to measure the flow. The mounting is done with the help of the selected flow tube (R-thread or flange connection). The flowmeter can store two calibration curves, allowing the sensor to be used in two different gases without loss of accuracy. The optional color display shows all measured values, such as flow and total consumption. The display can also be used to manage sensor settings such as pipe diameter, gas type or output settings. The sensor offers two different signal output options. It can have an isolated analog and pulse output to read the current and total consumption. Alternatively, a MODBUS RTU interface can be used to access all measured values ​​via the digital interface. Various settings such as gas type, flow unit, reference standards can be set at the factory as required. If it is necessary to change the settings on site, the free S4C-FS software for Android phones can be used to wirelessly access the flowmeter settings.
