Price of lightweight plastic rotor flowmeter

The main measuring components of the plastic rotor flowmeter SLLZB-S are a conical plastic tube with a small end facing downwards and a large end facing upwards, and a float that can move up and down inside. When the fluid flows through the conical plastic tube from bottom to top, a pressure difference is generated between the upper and lower parts of the float, and the float rises under this pressure difference. When the force that causes the float to rise is equal to the combined force of gravity, buoyancy, and viscosity acting on the float, the float is in an equilibrium position. Therefore, there is a certain proportional relationship between the fluid flow rate through the SLLZB-S plastic rotor flowmeter Huai'an Senling Instrument Co., Ltd. and the rising height of the float, that is, the flow area of the flowmeter. The position height of the float can be used as a measure of flow rate.

I. Overview
The main components of the plastic rotor flowmeter, such as the cone tube, are made of AS and ABS plastics, which have good corrosion resistance. The product also has the characteristics of reasonable structure, small volume, light weight, and the cone tube is not easy to break. The plastic tube float flowmeter can be widely used in industrial sectors such as chemical, environmental protection, and food.
2、 Principle and Structure
The main measuring component of a plastic rotor flowmeter is a conical plastic tube with a small end facing downwards and a large end facing upwards, and a float that can move up and down inside. When the fluid flows through the conical plastic tube from bottom to top, a pressure difference is generated between the upper and lower parts of the float, and the float rises under this pressure difference. When the force that causes the float to rise is equal to the combined force of gravity, buoyancy, and viscosity acting on the float, the float is in an equilibrium position. Therefore, there is a certain proportional relationship between the fluid flow rate flowing through the flowmeter and the rising height of the float, that is, the flow area of the flowmeter. The position height of the float can be used as a measure of flow rate.
3、 Installation of plastic rotor flowmeter
〔1〕 Before installation, gently take out the foam support in the instrument with pointed nose pliers, and then install it again. During installation, pay attention to whether the rubber washer is installed in the groove of the connecting pipe to prevent water leakage.
〔2〕 The interface of the flowmeter can be connected with matching ABS plastic pipes, PVC plastic pipes, glued together, or connected with plastic methods and then connected with metal flanges.
〔3〕 The flowmeter must be installed vertically without obvious inclination, and its installation height should be convenient for reading the float. When reading, the line of sight should be level with the float. [General standard: The optimal flow rate required is 50% -70% of the maximum flow rate of the flowmeter, and it is recommended not to use high flow rates.]. []
〔4〕 There should be a straight pipe section of 5 times the diameter of the instrument at the upstream and downstream inlet and outlet of the instrument.
〔5〕 The pressure of the side fluid must be stable. If the fluid is too strong and unstable, it will cause the float to fluctuate and cannot be measured correctly. A buffer or setting device should be installed upstream of the flowmeter.
〔6〕 The plastic tube rotor flowmeter should be installed vertically, and the angle between the centerline of the flowmeter and the plumb line should not exceed 5 degrees.
The connection methods can be divided into four types: plug-in, welding, threaded, and flange connection.
