Description

The S401 compressed air flow meter is designed to be easy to use, affordable and it's offering a wide measurement range. This makes it easy for you to choose the right flow meter, the S401 which fits your needs. The S401 is a thermal mass flow meter, based on its measurement principle it's not required to compensate the compressed air pressure and temperature, so you do not need any additional measurement installations to measure the flow and the consumption. Due to the thermal mass flow, the flow meter is also well suited to be used in any other gas as Nitrogen or many other technical gases. The S401 sensor technology offers you a high resolution and a high sampling rate, which results in a very fast and precise measurement. The flow meter is able to save two calibration curves, due to this the sensor can be used in two different gases without any loss of accuracy. The optional color display is designed to show all measured values like actual flow and total consumption. At the same time, the display can be used to manage the sensor settings like pipe diameter, gas type or output settings. The S401 flow meter offers two different signal output options. It can be equipped with an isolated analog and pulse output to read out the compressed air flow and the total compressed air consumption. Alternatively, a MODBUS RTU interface can be used to access all measured values via the digital interface. Since the flow meter can be easily installed through a standard ball valve, it can be easily removed for a calibration, without shutting down your compressed air system. Various settings such as gas type, flow unit, reference standards, can be set ex factory according to your needs
