Proline Promass A 100

Summary

Product identification

• Product line: Proline Promass A 100
• Type: Coriolis flowmeter
• Headline: The single-tube flowmeter for smallest flow quantities with an ultra-compact transmitter.

Field of application

Promass A is designed for highly accurate measurement of small quantities of liquids and gases, suitable for high and low pressure applications. It features the smallest transmitter housing available, delivering full performance in a compact footprint. This makes it a preferred choice for system integrators, skid builders, and equipment manufacturers.

Benefits

• Highest process safety – self-drainable measuring tube design
• Fewer process measuring points – multivariable measurement (flow, density, temperature)
• Space-saving installation – no in/outlet run needed
• Space-saving transmitter – full functionality on the smallest footprint
• Time-saving local operation without additional software and hardware – integrated web server
• Integrated verification – Heartbeat Technology
