Abstract
There is provided a differential pressure type flowmeter that includes an orifice provided in a main flow channel, a first pressure sensor configured to detect pressure of fluid on an upstream side of the orifice, a second pressure sensor configured to detect pressure of fluid on a downstream side of the orifice, a first pressure introduction flow channel configured to guide the fluid on the upstream side of the orifice to the first pressure sensor, and a second pressure introduction flow channel configured to guide the fluid on the downstream side of the orifice to the second pressure sensor, wherein a flow channel length and a flow channel diameter of the first pressure introduction flow channel coincide with those of the second pressure introduction flow channel, respectively, and a ratio of the flow channel length to the flow channel diameter is not less than 20 times and not more than 30 times.
