The highly accurate Promass H is destined for applications
requiring maximum corrosion resistance and guarantees optimal
safety for chemically aggressive fluids. With its compact
transmitter Promass H 300 offers high flexibility in terms of
operation and system integration: access from one side, remote
display and improved connectivity options. Heartbeat Technology
enables process safety at all times.
Measuring principle operates independently of physical fluid
properties such as viscosity or density
Highly accurate measurement of liquids and gases in applications
requiring highest corrosion resistance
Device properties
Measuring tube made of Tantalum, Zirconium
Nominal diameter: DN 8 to 50 (3/8 to 2"")
Medium temperature up to +205 °C (+401 °F)
