Two new meters have been added to the Promass Q coriolis flowmeter line from Endress+Hauser. Available for pipes up to 10-in. to measure flow rates up to 18,900bph, the new 4-tube technology enables use in the oil and gas industry. In addition to mass and volumetric flow, Promass Q also records process density and temperature. Compared to meters with two measuring tubes, four tubes reliably measure 25% greater flow rates and reduce pressure loss while pumping. Promass Q flowmeters are available in stainless steel and IP66/67-rated materials and are rated for process temperatures ranging from -321°F to 401°F. Additionally, Promass Q ratings are in compliance with IEC 61508.
