The company says its S418-V combines an accurate thermal mass flow sensor designed solely for vacuum flow measurement with an absolute pressure sensor, LED display and datalogger for continuous standalone or remote monitoring through 4-20mA, Modbus/RTU or M-Bus. Currently available in 4 sizes up to DN25, the S418-V can help to identify leakage losses through change in pressure and flow before vacuum failure occurs, to guide preventative maintenance.
