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.
Mobile configuration and real-time data
Various settings such as gas type, flow unit and reference standards, can be set ex-factory according to your needs. If settings need to be changed on site, they can be done using the free S4C-FS smart phone application. This enables users to change the settings of the flow sensor wirelessly on site. Flow meter settings are well protected from unwanted access with use of a unique QR access code for each meter.
