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 enables measurement reliability and compliant verification.
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. Combines in-line viscosity and flow measurement with a transmitter remote version with up to 4 I/Os. Measuring liquids and gases in applications requiring low pressure loss and gentle fluid treatment.
