1. The difference between turbine flowmeter and vortex flowmeter
1. Different design principles. Turbine flowmeter focuses on measuring liquids and belongs to the velocity beam flowmeter. The principle is to use the relationship between the rotational angular velocity of the impeller placed in the liquid and the liquid flow velocity to calculate the liquid flow rate by measuring the impeller speed. The vortex flowmeter is designed and manufactured based on the Karman vortex principle. The principle of fluid oscillation is applied to measure flow rate. When the fluid passes through the vortex flow transmitter in the pipeline, two columns of vortices proportional to the flow velocity are alternately generated up and down behind the vortex generator in the triangular column. The release frequency of the vortices is related to the average velocity of the fluid flowing through the vortex generator and the characteristics of the vortex generator.
2、 The vortex flowmeter is mainly used for flow measurement of industrial pipeline media fluids, such as gases, liquids, vapors, and other media, with different application ranges. Turbine flow meters are widely used to measure the amount of trapped gas in various objects such as petroleum, organic liquids, inorganic liquids, liquefied gas, natural gas, coal gas, and low-temperature fluids.
3、 Different characteristics of turbine flow meters include simple structure, few processed parts, light weight, easy maintenance, high flow capacity (large flow rate that can pass through the same caliber), and adaptability to high parameters (high temperature, high pressure, and low temperature). The characteristics of vortex flowmeter are small pressure loss, larg
2. What is the measuring structure of the flange clamp type? The so-called flange mounted vortex flowmeter is one of its measurement methods, and the flange mounted virtual macro installation is also the most commonly used and common structural measurement form. The body of the flange mounted vortex flowmeter does not have a connecting flange. Generally, when connected to the pipeline, the flowmeter is clamped between two specialized flanges and then bolted to the pipeline. 3. Installation requirements for vortex flowmeter
Installation requirements for flange clamp type pipeline: 1. Spot welding and positioning of flange and pipeline.
. Remove the flowmeter, weld the flange as required, and clean all protruding parts inside the pipeline. Install a sealing gasket with the same diameter as the pipeline in the inner groove of the flange, and install the flowmeter into the flange. The flow direction of the flowmeter should be the same as the fluid direction, and then tighten it with bolts. Installation requirements for plug-in instruments: 1. Use gas welding to open a circular hole slightly smaller than 100mm on the pipeline, and clean and tidy the burrs around the circular hole to ensure smooth rotation of the measuring head. Weld the flange provided by the manufacturer at the circular hole of the pipeline, with the flange axis perpendicular to the pipeline axis. Install
