3.2 Design
SITRANS FVA250 is an all-metal variable area flowmeter with a standard length of 250 mm
(9.84 inch). The momentary flowrate is indicated in volume or mass per time unit. The
measured value is indicated directly on the scale.
The equipment can be supplied with accessory electrical components and touch-sensitive
switches for process monitoring and control.
Features
● Standard model can be supplied at short notice
● Robust all-metal fitting with shock-proof housing
● Applicable for the measurement of aggressive and combustible materials
● Applicable for high pressures and temperatures
● Product and percentage scale
● Optionally supplied with heating and cooling jackets fitted
● Contamination-resistant design
MEM transducers
The measuring transducers MEM / MEM-PPA are installed in the flowmeter FVA250. In this
manner the range of volume flow measurement is covered.
The measuring transducers MEM / MEM-PPA are designed for installation in a housing that
is at least compliant with enclosure rating IP20.
