C581 Single stream Flow & Energy Computer

Name: C581 Single stream Flow & Energy Computer
Brand: FLUIDWELL
Availability: InStock

The C581 flow and energy computer measures the actual flow, temperature and pressure and uses the IAPWS determinations or Water-Glycol tables to calculate the energy, mass and volumetric flow. The linearization enhances accuracy in any flow range. The large logging register contains all measured and calculated values. The robust IP66/67, Type4X aluminum field enclosure, withstands extreme weather and industrial conditions.
