eFlo 2.0 Standard gas flow measurement and control up to 350 mbar
Measures and controls the flow of common process gases up to 350 mbar, with pressure and temperature compensation and calibration that can be certified in place.
Flow meters
Measures and controls the mass flow rate of gases and liquids in industrial and commercial applications where accuracy is critical.
SSi mass flow meters are used in a wide range of industrial and commercial applications to measure and control the mass flow rate of gases or liquids wherever accuracy and precision are critical. This meter measures mass per unit of time rather than volume per unit of time, which is what standard manual or electronic flow meters report. Pressure and temperature are compensated by two dedicated sensors, so the indicated value stays correct as process conditions change.
The meter is supplied with NIST-traceable calibration and with flow verification ports that allow the calibration to be checked in place, which satisfies AMS and CQI verification requirements. Integrated communications and configurable flow alarms let the instrument be tied directly into process controllers, PLCs and plant SCADA, while the built-in totaliser records gas consumption for cost analysis.
