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 compact transmitter Promass I 300 offers high flexibility in terms of operation and system integration: access from one side, remote display and improved connectivity options. 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
Device properties
Straight, easy-to-clean single-tube system
TMB technology
Measuring tube made of Titanium
Compact dual-compartment housing with up to 3 I/Os
Backlit display with touch control and WLAN access
Remote display available
Benefits
Energy-saving – full bore design enables minimal pressure loss
Fewer process measuring points – multivariable measurement (flow, density, temperature)
Space-saving installation – no in-/outlet run needs
Full access to process and diagnostic information – numerous, freely combinable I/Os and Ethernet
Reduced complexity and variety – freely configurable I/O functionality
Integrated verification – Heartbeat Technology
