Problems solved by technology

For pipelines transporting saturated steam, there are both saturated steam and a small amount of saturated liquid in the pipeline. When measuring the flow of saturated steam in the pipeline, the pressure head of the Bitoba flow sensor is placed in the saturated steam, because saturated steam has A certain pressure will cause the silicone oil in the full and static pressure guide tube of the Bitoba flow sensor to overflow and drip, causing errors in the transmitted full and static pressure signals, and ultimately affecting the measurement accuracy of saturated steam flow

Abstract

The invention discloses a phase change flow saturated steam flowmeter, comprising a horizontal short round tube and a Bitoba flow sensor inserted into the horizontal short round tube from the top wallof the horizontal short round tube. The Biotaba flow sensor is connected to a first differential pressure transmitter. The flowmeter further comprises a liquid level measuring device mounted on the horizontal short round tube for measuring the liquid level in the horizontal short round tube. The Bitoba flow sensor comprises a pressure head, a full pressure guiding tube, and a static pressure guiding tube connected to the full pressure guiding tube. The left side and the right side of the lower section of the pressure head have full pressure holes and static pressure holes. The inside of the pressure head has a full pressure channel and a static pressure channel. A full pressure balance hole and a static pressure balance hole are provided on the left and right sides of the pressure head. The full pressure balance hole and the static pressure balance hole are respectively connected with the top of the full pressure channel and the static pressure channel. The Bitoba flow sensor furthercomprises a full pressure water storage hole and a static pressure water storage hole extending from the top of the pressure head to the lower part of the full pressure balance hole and the static pressure balance hole. The full pressure guiding tube and the static pressure guiding tube respectively extend into the full pressure water storage hole and the static pressure water storage hole. The phase change flow saturated steam flowmeter can accurately measure the flow rate of the saturated steam in a pipeline.
