V cone flow meter selection and installation conditions

Abstract: V-cone flow meter selection and installation condition information is provided by excellent flow meter and flow meter manufacturers and quotation manufacturers. V Cone flowmeter installation site selection factors: V Cone flowmeter can work normally even under relatively harsh conditions, but for long-term safe and stable use, the following points should be paid attention to during installation: 1. The impact and impact of the installation site Vibration V cone flow out. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of the V-cone flowmeter selection and installation conditions. Selection elements for the installation site of the v-cone flowmeter: The v-cone flowmeter can work normally even under relatively harsh conditions, but for long-term safe and stable use, the following points should be paid attention to during installation: 1. The impact of the installation site and the The vibration V-cone flowmeter is designed to withstand certain shocks and vibrations. However, it should also be installed in a place with no or little vibration as much as possible. 2. Ambient temperature conditions of the installation site Please try to avoid installing the flowmeter in a place where the ambient temperature changes greatly. If the installation location is directly exposed to thermal radiation or exposed to the sun and rain, measures should be taken for waterproofing, heat insulation radiation and ventilation. 3. The ambient air conditions of the installation site The V-cone flowmeter should be avoided as far as possible in a corrosive environment. If it is used in a corrosive environment, it should be well ventilated and pay attention to avoid corrosive gases or liquids from immersing in the instrument. V-cone flowmeter has the following installation forms: 1. Pipe flange type: It means that there are installation flanges at both ends of the flowmeter. The connection with the installation flanges (also called user flanges) of the same specifications at both ends of the process pipeline is a relatively common structural form, and the applicable diameter (dn50mm ~ 3000mm). This form is suitable for use when the throttling device and the differential pressure transmitter are installed separately. It is generally used when measuring steam flow, and can also be used when measuring other high-temperature media. 2. Flange clamping type: It is used for the installation of small-mouth flowmeters. Each flowmeter and process pipeline only need 2 flanges. The flange is welded with the process pipe, and the flowmeter is clamped between the two flanges. The installation method here is the same as the vortex flowmeter (≤300mm) installation method is the same. 3. Small caliber integrated type: applicable caliber≤dn40mm, medium temperature≤120°C fluid. The structure is to directly combine the differential pressure transmitter with the tower flowmeter into a whole. There is no pressure guiding pipe, pressure taking valve and three-valve group between them. Makes installation very simple (same as vortex flowmeter installation). When the differential pressure transmitter adjusts the zero point, the valve of the process pipeline needs to be closed, and then the zero can be adjusted. Note: This installation method cannot be used for measuring high temperature medium, because the high temperature medium will enter the measuring chamber of the differential pressure transmitter and damage the measuring diaphragm of the transmitter. 4. Pipeline butt welding: It means that the tower flowmeter and the process pipeline cannot be flanged (the body of the flowmeter cannot be flanged), and the flowmeter and the process pipeline are directly welded together during installation. The cost of this structure is relatively low (reduce the cost of 4 flanges), and it is a one-time installation. Generally used for larger diameter occasions. 5. Conventional fluid integrated type: refers to the medium temperature≤120 ℃ fluid, suitable for pipe diameter: dn50 ~ dn3000. According to different fluids and user requirements, the manufacturer welds (or assembles) valves and three-valve groups on the flowmeter for users before leaving the factory. The flowmeter and transmitter can be assembled together by the user during field installation. 6. Steam integrated type: When measuring the steam flow, the transmitter and the tower flowmeter are assembled together, and our company should be assembled between the transmitter and the flowmeter.“Three-valve group for steam”components, thus eliminating the pressure guiding tube and greatly simplifying the pressure taking structure. 7. Liquid antifreeze type: refers to the installation between the tower flowmeter and the transmitter by our company“Liquid special isolation tank”, The tank is equipped with a special medium, which can not freeze at a lower temperature. This installation method is used when measuring liquids, especially when the outdoor environment is relatively low in northern winter. Often the liquid in the measuring chamber of the transmitter is easy to freeze and damage the transmitter. 8. Square pipe flange type: It means that the process pipe is a square pipe, and the flowmeter measuring pipe is a circular pipe, and the two pass through a specially made pipe.“square-circle”connector to connect. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'V cone flow meter selection and installation conditions'
