DK900 glass rotor flowmeterPVDF glass rotor flowmeter DK900Overview

DK900 glass rotor flowmeterPVDF glass rotor flowmeterDK900Glass rotor flowmeter is a process detection instrument for measuring the flow rate of single-phase non pulsating fluid (liquid or gas) in a closed pipeline. It is suitable for measuring strongly corrosive media and is resistant to strong acid and alkali corrosion,PVDFAdvantages such as high material strength and strong corrosion resistance

New corrosion-resistant instrument developed by Changzhou Shuangcheng Thermal Instrument Co., LtdPVDFProducts made of materials, with complete specifications and varieties, advanced manufacturing technology, and stable and reliable quality,DK900 glass rotor flowmeterPVDF glass rotor flowmeterDK900The series of glass rotor flow meters are widely used in chemical, petroleum, light industry, pharmaceutical, fertilizer, synthetic fiber, food, dye, papermaking, national defense, scientific research and other units. They can also be customized with special flow rates and materials for customers.

The glass rotor flowmeter, manufactured with professional technology and equipment, has advantages such as high measurement accuracy, good interchangeability, wide measurement range, multiple connection methods, and easy installation and maintenance compared to similar domestic products. In addition, it can provide users with flow scales for different fluids, states, and viscosities based on their physical quantities such as temperature, pressure, density, and viscosity, solving the problem of correcting measurement display values and facilitating user use.

working principle

DK900 glass rotor flowmeterPVDF glass rotor flowmeterDK900The series glass rotor flowmeter is a variable area flowmeter, mainly composed of a vertically expanding glass cone tube from bottom to top and a float that can move up and down with the flow rate (see Figure 1). When the fluid flows through the glass cone tube from bottom to top, the fluid can generate lift on the floatSThe buoyancy of fluidsARaise the float, as the annular flow area between the float and the inner wall of the cone tube increases, the lift generated by fluid kinetic energy on the float decreases accordingly. When liftSWith buoyancySThe sum is equal to the weight of the float itselfGWhen the float is in equilibrium, it stabilizes at a certain height, which represents the flow rate of the fluid through the flowmeter. Because there is a certain proportional relationship between the flow rate through the flowmeter and the rising height of the float, that is, the flow area of the flowmeter, the height position of the float can be used as two degrees of flow rate.
