A robust flowmeter designed for superheated steam

| By Chemical Engineering

Built for longterm use, the flowmeter has no exposed cables or sensitive elements, and features a full-bore flow sensor with no moving parts or obstructions. According to the manufacturer, the meter can maintain its measuring accuracy without maintenance or subsequent calibration for up to 20 years. The Optisonic 8300 is rated for pressures up to 200 bars and temperatures up to 540°C, with higher- rated units available on request. Temperature and pressure sensors connected to the device provide the integrated flow computer with data to calculate steam mass flow, eliminating the need for an additional computer. — Krohne, Inc., Peabody, Mass.
