High Flow Economical Mass Flow Meters and Controllers
Our Top-Trak® Model 826 and Model 827 high flow MFM’s directly measure the mass flow rate of gases in flow ranges from 0-75 slpm up to 0-175 slpm. The Model 826 and Model 827 are for measurement of air and ALL inert gases & mixtures. These models serve a wide variety of gas flow applications compatible with the anodized aluminum flow body. Both models offer standard 0-5 VDC or 4-20mA output signals and accept NPT pipe thread connections.
Our Model 826 is equipped with a large tiltable LCD readout available in your choice of engineering units. The LCD readout can be mounted on the instrument or on a remote panel. Our Model 827 is an OEM configuration that comes without the LCD readout. Sierra’s Platinum Sensor Technology to eliminate zero-drift and create excellent long-term reliability is utilized in the design of both models.
