Development History of Flowmeters

- Jun 02, 2019-

As early as 1738, Daniel Bernoulli of Switzerland used differential pressure method to measure water flow based on the first Bernoulli equation. Later, G. B. Venturi, an Italian, studied using Venturi tubes to measure flow, and published the results in 1791.

In 1886, Herschel, an American, used Venturi Tube as a practical device for measuring water flow.

From the beginning to the middle of the 20th century, the original measurement principle gradually matured. People no longer confined their thinking to the original measurement method, but began a new exploration.

In the 1930s, there was a new method to measure the flow rate of liquids and gases by acoustic wave, but no great progress had been made until the Second World War. It was not until 1955 that a Maxon flowmeter with acoustic cycle method was invented to measure the flow rate of aviation fuel.
