1. What is a delta flowmeter? The delta flowmeter produced by Jiangsu Technical Control Instrument Co., Ltd. for Boshu is a device that measures flow rate through differential pressure and is developed based on the principle of pitot tube flow rate measurement. It can measure the flow rate of fluids such as liquids, gases, and vapors. Due to the absence of moving parts, almost no pressure loss, easy installation and maintenance, and extremely low operating costs, it is highly favored by users. The sensor is composed of a detection rod, a silver false pressure tap, and a guide rod. It crosses the inside of the pipeline perpendicular to the pipeline axis. Multiple pressure measuring holes are set on the upstream side of the measuring rod to measure the average total pressure, and static pressure measuring holes are set on the downstream and side flow surfaces. They are respectively led out by the total pressure guide tube and the static pressure guide tube. Based on the differential pressure between the total pressure and the static pressure, the flow rate through the pipeline is calculated. The static pressure on the back flow surface of the sensor can also be replaced by the static pressure on the flow tube wall. The average velocity tube flow transmitter is a flowmeter composed of sensors, pressure accessories, differential pressure transmitters, pressure transmitters, flow integrators, and other supporting components. Equipping the averaging tube flow sensor with our companys differential pressure transmitter, pressure transmitter, temperature transmitter, and flow integrator can form various types of averaging tube flow meters. Various types of averaging tube flow meters can also be composed of differential pressure transmitters, pressure transmitters, temperature transmitters, and flow integrators produced by any manufacturer.

Secondly, the principle of sock combustion is based on the development of the pitot tube speed measurement principle. It determines the flow rate by multiplying the average flow velocity of the pipeline and the effective cross-sectional area of the pipeline.

. The velocity distribution in general pipelines is uneven. If it is a fully developed fluid, its velocity distribution follows an exponential law. For accurate measurement, divide the entire circular cross-section into multiple semicircles and semicircles with equal unit areas. The detection rod of the sensor is composed of a hollow metal tube, and multiple pairs of total pressure holes are drilled on the upstream side, which are located in the center of each unit area and reflect the flow velocity within each unit area. As each total pressure hole is connected, the average total pressure value transmitted to each point in the detection rod is led to the high-pressure joint through the total pressure outlet pipe and sent to the positive pressure chamber of the sensor. When the sensor is correctly installed on a process pipeline with a sufficiently long straight section, there should be no vortices on the flow cross-section, and the static pressure of the entire cross-section can be considered constant. There are detection holes on the back or side of the sensor, representing the static pressure of the entire cross-section. The static pressure outlet pipe is led from the low-pressure joint to the negative pressure chamber of the sensor. The square of the pressure difference between the positive and negative pressure chambers is directly propo
