waist wheel flow meter

The waist wheel flow meter is a high-precision measuring instrument used for continuous or intermittent measurement of flow in pipelines. It has the characteristics of high precision, high reliability, light weight, long life and easy installation and use, which are the typical characteristics of the volumetric flow meter. It is mainly composed of three parts: the metering chamber seal coupling and the counter. It can indicate the cumulative flow rate and instantaneous flow rate on site. It can be equipped with a transmitter and an intelligent flow controller to achieve long-distance measurement and control. It is widely used in petrochemical industry, electric power, metallurgy, transportation, food processing, medicine, national defense, commercial trade and other departments to accurately measure fluids such as petroleum and petroleum products chemical solutions.
Working principle of waist wheel flowmeter
When the liquid to be measured flows through the measurement chamber, a pressure difference is formed at the inlet and outlet of the flow meter, and the waist wheel rotates driven by this pressure difference. At the same time, the two waist wheels are kept rotating continuously through a pair of driving gears fixed on the waist wheel shaft. As the waist wheel rotates, the liquid is continuously discharged from the flow meter through the metering chamber. The amount of liquid flowing through each pair is four times the volume of the metering chamber. The number of rotations is decelerated through the sealed coupling deceleration mechanism and then transferred to the counter. The counter indicates the instantaneous flow rate and cumulative flow rate of the liquid. Installing a transmitter in the counter mechanism creates a waist wheel flowmeter with a transmitter. When matched with display instruments or microcomputer systems, automatic measurement and control of remote transmission (quantitative accumulation, instantaneous and other functions) can be realized. Instructions for use can also be found in the display instrument classification instructions.
