Promass 84A

The single‐tube flowmeter for smallest quantities with custody transfer functionality. Measuring accurately smallest quantities of liquids and gases for continuous process control.

Highest process safety – self‐drainable measuring tube design. Fewer process measuring points – multivariable measurement (flow, density, temperature). Space‐saving installation – no in/outlet run needs. Nominal diameter: DN 2 to 4 (¹⁄₁₂ to ¹⁄₈"). Process pressure up to 400 bar (5800 psi).

Quality – designed for custody transfer; featuring worldwide recognized metrological approvals. Flexible data transfer options – numerous communication types. Automatic recovery of data for servicing. 4‐line backlit display with touch control. Device in compact or remote version.
