(316/316L)" "Field of application
Promass A is known for its highly accurate measurement of small
quantities of liquids and gases for high pressure and low pressure.
Combined with the smallest transmitter housing available today it
delivers full performance on the smallest footprint. Promass A 100
is the preferred choice for system integrators, skid builders and
equipment manufacturers. Available with an ultra-compact stainless
steel hygienic housing it can be placed even into the most compact
rigs.
Measuring principle operates independently of physical fluid
properties such as viscosity or density
Measuring accurately smallest quantities of liquids and gases for
continuous process control.
Device properties
Nominal diameter: DN 1 to 4 (1/24 to 1/8"")
Process pressure up to 400 bar (5800 psi)
