Page 6: Product Description
PRODUCT DESCRIPTION The flowmeter of the series EE772, based on the measurement principle of thermal mass flow, is suited for the measurement of flow of air and gasses in pipelines. Measurement of for instance the consumption of compressed air, nitrogen, helium, CO2 or other non-corrosive and non-flammable gasses. The EE772 measures the volume flow at standard conditions according to DIN 1343 (P =1023.25 mbar;... -
