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. Chemically resistant single-tube flowmeter with a compact, easily accessible transmitter. Highly accurate measurement of liquids and gases in applications requiring highest corrosion resistance.
