Mass flow meter S415

thermaldigitalnitrogen

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.
