TopTrak 822/824 – Sierra Economical Thermal Mass Flowmeter

Economical 800 Series Mass Flow Meters

Sierra Instruments’ TopTrak® 820 Mass Flow Meter is designed to replace volumetric flow rate devices at a comparable installed cost. No temperature or pressure corrections are required, as in the case of most other flow monitoring devices, such as rotameters, turbine meters or critical orifices. Available in flow ranges from 0 to 10 sccm up to 0 to 50 slpm, TopTrak is suitable for any clean gas flow measurement application. Wetted surfaces are rugged 316 stainless steel, nickel plating, 6/6 reinforced Nylon® and Viton® “O” rings; all are corrosion-resistant. The 820 measures and displays the mass flow rate directly in sccm or slpm. The integral instrument display is tiltable over 180° for easy viewing and can be removed for remote panel mounting. A 0 to 5 VDC or 4 to 20 mA output signal linearly proportional to gas mass flow rate is provided for recording, data-logging or control. This device is widely used in a variety of flow validation and calibration applications-by dozens of instrument OEMs and in a multitude of laboratory, test and analytical operations.
