The Sierra 826 Top-Trak® Hi-Flow Mass Flow Meters directly measure the mass flow rate of gases in flow ranges from 0-75 slpm up to 0-175 slpm. The Model 826 is for measurement of air and ALL inert gases & mixtures. The 826 thermal mass flowmeter serves a wide range of inert gas flow applications including process control, flow research, instrument OEMs, gas panels, and cell culture maintenance.
The Sierra Model 826 Hi-Flow Mass Flow Meter with Display offers standard 0-5 VDC or 4-20mA output signals. The Model 826 is equipped with a large tiltable LCD readout available in your choice of engineering units. The LCD readout is mounted on the instrument, however the display can also be configured for remote mounting with cable lengths up to 100 feet maximum by ordering Option RD(). A versatile optional seven digit, user configurable, totalizer is also available by ordering Option T.
Sierra’s Patented Platinum Sensor Technology is utilized in the design of the flowmeter. This technology virtually eliminates zero-drift and provides excellent long-term stability. The 826 Mass Flow body is constructed of anodized aluminum, with Viton® "O"-rings and our patented 316 stainless steel sensor. Linear, 0-5 VDC output signal; input power 12-15 VDC. Your choice of inlet/outlet fittings. A male 9 Pin "D" mating connector is provided for input/output signals. Calibrated for flow ranges from 0-75 slpm to 0-175 slpm equivalent nitrogen flow; 1.5% Full Scale accuracy; maximum temperature 122°F (50°C); maximum pressure 150 psig (10.3 barg). CE Approved.
