McMillan Model 50SD Mass Flow Meters feature an integrated flow rate display and are constructed from stainless steel. They are capable of measuring virtually any clean, dry gas as low as 0-20 sccm or as high as 0-100 L/minute.
McMillan Model 50SD Mass Flow Meters feature an integrated flow rate display and are constructed from stainless steel. They are capable of measuring virtually any clean, dry gas as low as 0-20 sccm or as high as 0-100 L/minute. Repeatable results are achieved using a patented thermal mass flow sensor design. This proven design minimizes zero drift while maintaining fast response and linear outputs.
Because of the compact size and economical cost of these products, the Model 50SD Mass Flow Meters are suitable for a wide variety of industrial, commercial, laboratory and O.E.M. applications.
Thermal mass flow meters feature fast response, virtually zero maintenance, and precise measurement. These are essential qualities for today’s variety of applications.
Flow ranges from 0-20 sccm up to 0-100 L/minute are available. Consult the factory for custom requirements.
Units may be ordered to operate with either 12 VDC or 24 VDC power. Various power adapters are available for use with 12 VDC versions.
Choose from either 0-5VDC or 4-20mA linear outputs.
All models have a standard accuracy specification of ±1.5% F.S. accuracy (including linearity). NIST traceable calibration certificates are optional on some models.
All units have compression-type tube fittings as standard. Consult Product Configurator for available materials and sizes.
All units have a 36” (92 cm) output cable, terminated with a 6-pin PS/2 style connector. An optional mating cable assembly, terminated with pigtail leads, is recommended to facilitate wiring.
50SD units feature stainless steel construction. See specifications for detailed materials in gas path.
Backlit LCD display provides flow rate in realtime. Units for ranges up to 1,000 sccm will display flow in cc/min, and ranges above 1,000 sccm will display flow in L/min.
Units may be calibrated for virtually any clean, dry gas. Several non-standard gas selections are available as indicated in the Product Configurator. Contact factory for calibration information on non-standard gases.
