Calculation of pressure loss and selection of steam flowmeters (beginner, seeking help)
Thread Content
The steam flow meter is a orifice plate flow meter with a size of 998 mm, and the steam pressure is 4.5 kg. Some people have calculated that the permanent pressure loss of the orifice plate can reach 524 kW (with a pressure loss of 230 mbar). Is this possible? If so, the annual pressure loss would amount to over 3 million yuan in terms of monetary value. Does anyone have a better method for calculation? Thank you for any assistance. I now want to switch to a velocity tube flow meter (Anubas flow meter). The data provided by the manufacturer indicates a pressure loss of 9 Pa; why is there such a large difference between the two pressure losses?
Our orifice plate flowmeter has never been used for measurement purposes; it can only serve as a reference for production control, and even then it suffers from many malfunctions.
