Coriolis flowmeter - Proline Promass 84A ©Endress+Hauser

The single-tube flowmeter for smallest quantities with custody transfer functionality

Promass A is known for its highly accurate measurement of small quantities of liquids and gases for high pressure and low pressure. Combined with the Promass 84 transmitter with touch control and a four line display Promass 84A measures accurately smallest quantities of liquids and gases for a wide range of very demanding applications. It will be the preferred solution for customers needing custody transfer measurement and using advanced functionalities like pulsating flow or fieldbuses.
