Field of application
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.
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.
Device properties
Nominal diameter: DN 1 to 4 (1/24 to 1/8")
Process pressure up to 400 bar (5800 psi)
Medium temperature up to +205 °C (+401 °F)
Robust, ultra-compact transmitter housing
High ingress protection: IP69K
Local display available
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 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
