TopTrak 822S/824S Mass Flow Meter for Corrosive & Toxic Gas
Brand: Sierra InstrumentsSierra Instruments TopTrak 820S is designed for precise measurement of any process gas in ranges from 0 to 10 sccm to 0 to 500 slpm.
Because all wetted materials are 316 stainless steel, the device accommodates most clean gases, including corrosives.
The 820S measures and displays the mass flow rate directly in any user defined gas mass units. The instrument display is tiltable over 180° for easy viewing and can be removed for remote panel mounting. A 0-5 Vdc or 4-20 mA linearly output signal proportional to gas mass flow rate is provided for recording, data-logging or control.
TopTrak's outstanding accuracy is a function of a high-stability platinum flow sensor. This sensor has been continuously tested for over two years. The maximum deviation (drift) during that time was less than 0.5%. The sensor's large internal diameter also prevents the clogging and contamination often associated with capillary type thermal mass flow meters.
TopTrak's broad range of sizes, electronics, process connections and input/output options provide flexibility, versatility and ultimately, the ideal instrument package for your specific application.
