进口高温高压涡街流量计美国阿卡迪亚品牌

进口高温高压涡街流量计Product description:

It includes a measuring pipe, a vortex generator, a vortex street probe, a meter rod, a meter rod seat and a meter head. The vortex generator is a triangular column, and one end surface of the triangular column is provided with a measuring hole. Two flow channels are respectively arranged on the symmetrical sides of the triangular column close to the end surface. The measuring hole is connected with the flow channel, and a convex flow limiting block is arranged between the two flow channels above and below the two sides, The vortex street probe extends into the measuring hole from the side of the measuring pipe. The vortex street probe is installed on the measuring pipe through the coordination of the first boss and the first step hole, as well as the second boss and the second step hole. High pressure sealing gasket and temperature resistant damping gasket are set. Heat insulation rings are set between the meter rod seat and the vortex street probe and the measuring pipe. Heat conduction devices are set on the meter rod. Vortex flowmeter has high sensitivity and accuracy, good sealing performance, good temperature resistance and pressure resistance, and can be used for measuring high temperature and high pressure steam.

进口高温高压涡街流量计characteristic:

Vortex flowmeter is a kind of flowmeter with relatively mature development. Its main advantages are: no movable parts, simple and firm structure, convenient installation, low maintenance cost, measuring range ratio generally above 10:1, relatively high accuracy, and gas measurement generally

Between 1.0 and 1.5, the liquid is generally measured at 1.0 level. When measuring the volume flow under working conditions, it is almost not affected by fluid density, pressure, temperature, viscosity and other parameters. It can be used for flow measurement of industrial pipeline medium fluid, such as gas, liquid, steam and other media. At present, ordinary vortex flowmeter can only be used in low pressure situations, such as measuring steam (within 2.5MPa) and compressed air (within 1.0MPa). When the medium pressure is up to 6MPa or even 10MPa or 25MPa in specific occasions, the ordinary vortex flowmeter is not applicable. In addition, the sensitivity of the general vortex flowmeter is not high, and the measurement accuracy will be affected due to the vibration of the pipeline and the surrounding environment, or even the measurement will become invalid.

进口高温高压涡街流量计Principle:

The vortex generating body is installed in the measuring pipe by welding or dismounting. When the fluid will not erode, block or damage the vortex generator, the welding method can be selected. When the vortex generator needs to be cleaned, flushed or replaced frequently due to corrosion, blocking, damage, etc., the detachable method can be used to facilitate cleaning and maintenance, so as to avoid the need to replace the entire flowmeter due to the damage of the vortex generator. The detachable method can be used to set bumps at both ends of the vortex generator, while the inner wall of the measuring pipe is provided with an appropriate groove, which can be positioned and clamped through the matching of the concave block and the groove, or positioned and fixed through the matching of the thread and the screw hole.
