DK800 glass rotor flow meter

Project Overview

The DK800 glass rotor flowmeter is manufactured using proprietary technology and equipment from Cloni, Germany. It has a lightweight structure, beautiful appearance, simple installation and convenient maintenance. There is no need to disassemble the whole machine. The KD800-2F glass rotor flowmeter can easily replace the cone. Tube and float, clear flow scale, sensitive adjustment, suitable for micro flow measurement in various industry sectors.

Installation

1. The flow meter should be installed vertically (the angle between the center line of the flow meter and the plumb line does not exceed 5°). For newly installed pipelines, the flow meter should be installed before installation. Flush the pipes clean. The measured fluid enters from the lower end of the flowmeter and exits from the upper end.

2. The fluid to be measured should not be mixed with large particles of oil or dirt, otherwise the float will get stuck or block the passage of the flow meter, affecting the normal operation of the flow meter. For example, the fluid to be measured contains large particles or is dirty. , a filter should be installed upstream of the flow meter as needed.

3. The pressure of the fluid to be measured must be stable when entering the flow meter. If the flow rate of the measured fluid is pulsating, it will cause the float to fluctuate and prevent normal measurement. A buffer or setter of appropriate size should be installed upstream of the flow meter.

Usage

1. When using the flow meter, the regulating valve should be opened slowly to prevent the float from suddenly impacting upward and damaging the glass cone.

2. The reading position of the float is the top of the ball float.

3. Rapid changes in temperature of the fluid being measured should be avoided during use.

4. If leakage is found in the flow meter in use, the inlet and outlet connectors, the pressure nut of the needle valve and the tightening ring at the lower end of the glass cone tube should be tightened (from left to right). clockwise). If the above method does not work, the sealing ring usually fails and should be replaced.

5. If the cone tube and float are contaminated, they should be cleaned in time.

6. Check the error of the flow meter regularly. Once the specified tolerance is exceeded, the float and glass cone should be replaced or recalibrated.

7. When the measured fluid and state (temperature, pressure) are inconsistent with the flowmeter, the indication value must be corrected according to the fluid and state at the time of use.

8. The DK800-() type is used for the measurement of general fluids, and the DK800-()F type glass rotor flowmeter is used for the measurement of corrosive fluids.

Customers must understand correct installation and use. Xinwang Instrument hopes that everyone can read the instructions when receiving the goods to prevent unnecessary problems.

This series of flow design is suitable for testing and adjusting small flow rates. Its features are light and simple in appearance, simple and convenient to install. The cone tube and float can be easily replaced without having to remove the whole machine from the pipe. The connection method is Hoses or metal pipe connections.

The main measuring element of the glass rotameter is a vertically installed conical glass tube with a small lower part and a large upper part and a float that can move up and down inside. When the fluid passes through the cone from bottom to topWhen the glass tube is shaped, a pressure difference is generated between the upper and lower parts of the float, and the float rises under the action of this differential pressure. When the rising force, the buoyancy force and the viscous lift force on the float are equal to the gravity of the float, the float is in an equilibrium position. Therefore, there is a certain proportional relationship between the fluid flow rate flowing through the glass rotameter and the rising height of the float, that is, the flow area of ​​the glass rotameter. The position height of the float can be used as a flow measurement.
