The S453 Compressed Air Flow Meter is specifically designed for heavy-duty and explosive (Ex) environments, providing precise and reliable thermal mass flow measurements for your industrial processes. This device integrates advanced technology and robust construction to ensure optimal performance in the most demanding conditions.
Durable ConstructionÂ
Built with stainless steel and nickel-plated components, the S453 is robust for harsh environments. Its IP67 housing makes it suitable for outdoor and industrial applications.
High AccuracyÂ
The meter boasts an accuracy of ±(1.5% of reading + 0.3% full scale) with 0.25% repeatability. The integrated color display and S4C-FS app for Android and iOS allow easy on-site verification and wireless configuration.
Data ManagementÂ
An integrated data logger records and stores measurement data. Multiple outputs, including Modbus/RTU, 2 x 4-20 mA, Pulse/Alarm, and Modbus/TCP over Ethernet/APL, enhance connectivity.
Flexible InstallationÂ
The S453 supports pipe sizes from DN25 to DN80 with R-thread or flange connections. It operates up to 5.0 MPa for Non-Ex versions and up to 1.6 MPa for Ex-approved applications.
