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 smallest transmitter housing available today it delivers full performance on the smallest footprint. Promass A 100 is the preferred choice for system integrators, skid builders and equipment manufacturers. Available with an ultra-compact stainless steel hygienic housing it can be placed even into the most compact rigs.
● 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
● 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
● Measuring principle operates independently of physical fluid properties such as viscosity or density
● Measuring accurately smallest quantities of liquids and gases for continuous process control.
