Installation method of bar-type average velocity tube flow meter

Abstract: The information on the installation method of the Pakistani average velocity tube flowmeter is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. The bar-type flowmeter is composed of a detection rod and a pressure port. It traverses the pipeline to the point where the pipeline is perpendicular to the central pipe axis. There are detection holes on the upstream surface of the detection rod and the backflow surface of the detection rod, which are guided by the total pressure respectively. The pressure pipe and the static pressure guide pipe are led out, according to the total pressure and static pressure. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The bar-type flowmeter is composed of a detection rod and a pressure port. It traverses the pipeline to the point where the pipeline is perpendicular to the central pipe axis. There are detection holes on the upstream surface of the detection rod and the backflow surface of the detection rod, which are guided by the total pressure respectively. The pressure pipe and the static pressure guide pipe are led out, and the flow through the pipeline is calculated according to the differential pressure value between the total pressure and the static pressure. 1. Before installing the bar-type flowmeter, the pipeline should be cleaned. When the measured medium is not clean, a filter should be added. Otherwise, the turbine and bearings are easily stuck, and the flow cannot be measured. 2. When disassembling and assembling the flowmeter, do not collide with the magnetic induction part. 3. Set the instrument coefficient before putting into operation. Check carefully to make sure that the wiring of the instrument is correct and the grounding is good before power transmission. 4. When installing the Ba-type flowmeter, the front and rear pipeline flanges should be horizontal, otherwise the pipeline stress will have a great influence on the flowmeter. 5. The flowmeter body should be made of 316 stainless steel for anti-corrosion. If it is an explosion-proof area, it must be explosion-proof. 6. Bearings generally have three specifications of tungsten carbide, polytetrafluoroethylene, and carbon graphite: tungsten carbide has high precision, and it is used as a standard part for industrial control; polytetrafluoroethylene, carbon graphite can prevent corrosion, and is generally preferred in chemical sites. The square of the life speed of the bearing is inversely proportional, so the best flow rate is 1/3 of the maximum flow rate. 7. The induction probe detects the movement of the rotating body and converts it into a pulse digital electrical signal. The output value of the electromagnetic coil voltage is close to a sinusoidal curve. The frequency range of the pulse signal changes linearly with the measured flow rate, and the typical range is 10: 1, 25:1 and 100:1 three specifications. The resistance of the electromagnetic coil is generally less than 2000Ω, more than this value may be damaged. The above is the whole content of this article.
