Thermal Mass Flow Meter S-415/S-418

The more accurately you monitor gas flow, the more likely you are to discover weak points in the process flow. Asymmetric velocity profiles, swirl and other factors such as pipe bends can quickly lead to incorrect readings.

Product Description

Features: • Flow and total consumption measurement with the new S 415 and S 418. These highly economical products will help you improve system efficiency and reduce compressed-air use, helping you lower operating costs. • Made especially for compressed air and nitrogen gas measurements. • Integrated display showing volumetric flow, • 4...20 mA analog output, pulse output, RS 485 Modbus RTU. • DN8, DN15, DN 20, DN 25 thread connection sizes • In both versions, a service app that lets the user check the flow meter's measurement results quickly and easily comes as standard. • With the flow meter app, connect to the product remotely, adjust product settings from where you sit and monitor consumption from a tablet or phone (Bluetooth feature). Such innovative solutions provide great convenience to users in the field. • The S 415 is best suited to general low-cost applications. • The S 418 is ideal for remote locations or for high accuracy with the built-in data logger. • Optional pressure sensing, Applications: The S-415 and S-418 thermal mass flow meters are designed to provide reliable and precise mass flow measurement, especially in compressed-air and industrial-gas lines. Thanks to their compact and durable construction they can be used in both fixed and mobile applications. They are widely preferred for energy monitoring, consumption analysis and leak detection in sectors with intensive compressed-air use. They are also an ideal measurement solution for businesses that want to increase process efficiency and keep costs under control.
