Vortex flow meters are a popular choice for dry saturated or superheated steam flow measurement. By design the vortex meter is a relatively simple device which can work over an extremely wide temperature range (-200ºC to +450ºC) and offers good measurement turndown of up to 30:1. Vortex meters are volumetric devices although more modern versions provide mass flow measurement by utilising built in temperature sensing technology. Endress & Hauser vortex meters can also determine the quality of steam passing through the meter. Steam quantity and quality measurement is detrimental to process operational safety and energy management.
