Promass 84A

单测量管流量计，用于极小流量测量，带计量交接功能。用于连续过程控制中的极小流量液体和气体的高精度测量。

最高过程安全性：自排空测量管。更少的过程测量点：多变量测量（流量、密度、温度）。所需安装空间小：无前后直管段长度要求。公称口径：DN 2...4 (¹⁄₁₂...¹⁄₈")。最大过程压力为400 bar (5800 psi)。

高品质：设计满足计量交接要求，通过公认计量机构的认证。灵活数据传输方式：多种通信类型。自动恢复数据，用于服务。四行背光显示，触摸键控制。提供一体式或分体式仪表。

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.
