Field of application
The straight single-tube design of Promass I provides in-line viscosity measurement in addition to mass flow, density and temperature measurement. With its innovative remote transmitter Promass I 500 maximizes installation flexibility and operational safety in demanding environments. Heartbeat Technology ensures compliance and process safety at all times.
Measuring principle operates independently of physical fluid properties such as viscosity or density
Measuring liquids and gases in applications requiring low pressure loss and gentle fluid treatment.
Device properties
Straight, easy-to-clean single-tube system
TMB technology
Measuring tube made of Titanium
Remote version with up to 4 I/Os
Backlit display with touch control and WLAN access
Standard cable between sensor and transmitter
Benefits
Energy-saving – full bore design enables minimal pressure loss
