Brooks Offers New Low Flow Rate Option for Model MT3809 Rotameters



HATFIELD, Pa. – Brooks Instrument, a world-leading provider of advanced flow, pressure, vacuum and level solutions, introduces a new low flow rate option for its Model MT3809 armored rotameters. The MT3809 is now capable of accurately measuring flow rates as low as 5 L/h of air and 0.08 L/h of water with this new option. The Brooks Model MT3809 armored rotameters are ideal for high pressure, high temperature and other demanding applications where safety is a concern. They provide ± 2% full scale flow accuracy, and are capable of measuring high and low temperature fluids. Other options available with the new low flow option include:


  • HART communications available from very low to high flow ranges.


  • 316 stainless steel indicator housing suited for corrosive atmosphere applications.


  • Transmitter option available for low flow, high temperature applications with process fluid temperatures to 150°C/300°F.


  • Leak points are eliminated because elastomers are not required for flanged meters.


  • Low flow, high pressure capacity can handle pressures to 6000 PSIG/400 bar. For more information about Brooks Model MT3809 armored rotameters with the new low flow option, visit brooksinstrument.com.
