Abstract: A method of determining vapor pressure of a fluid is provided. The method includes the steps of providing a meter (5) having meter electronics (20), the meter (5) being at least one of a flowmeter and a densitometer, and flowing a process fluid through the meter (5). A pressure of the process fluid is measured. The pressure of the process fluid is adjusted until a monophasic/biphasic boundary is reached. The flowing vapor pressure of the process fluid is determined at the monophasic/biphasic boundary.
