Qingdao Yongwangda Company WDLL series panel (pipeline) flowmeter brand WDLL flowmeter model WDLL type variable area flowmeter measurement range 0.003-33 (m3/h) accuracy level 4 applicable medium water working pressure 1 (MPa) working temperature 80 (℃) panel (pipeline) flowmeter is also a rotor (or float) flowmeter, and the measuring tube is made of high-quality transparent organic glass. Mainly used in water treatment and environmental engineering, it can also be used in chemical, petroleum, light industry, medicine, fertilizer, food processing, papermaking, scientific research and other departments to measure the flow rate of liquid single-phase non pulsating. The panel flowmeter has the characteristics of high transparency, intuitive reading, not easy to break, light weight balance, long service life, and easy installation and connection. AW has no direct relationship with flow meters, it may refer to the weight of the instrument.

Th

e calculation formula for pump flow rate is generally based on the formula Q=P η/2.73H, where Q is the flow rate in m3/h, P is the shaft power in KW, η is the efficiency of the pump in%, 2.73 is the constant, and H is the head in m. Secondly, the flow rate is inversely proportional to the head, that is, if the head is low, the flow rate is large. Accurate calculation requires a flow meter. Roughly estimate how many cubic meters flow per hour, and calculate the diameter and length of the pipeline. The shaft power of the water pump (kw) P=water delivery rate (liters/second) x head (meters)/102 x efficiency=flow rate x head x density x gravitational acceleration. 102 is the unit sorting constant. The efficiency of a pump=effective power of the water pump ÷ shaft power of the water pump (usually 50% -90%, higher for large pumps). The working principle of a centrifugal pump is that before starting the water pump, the pump and inlet pipe are filled with water. After the water pump runs, under the centrifugal force generated by the high-speed rotation of the impeller, the water in the impeller channel is thrown around and pressed into the volute, forming a vacuum at the impeller inlet. The water in the pool is sucked into the suction pipe under external atmospheric pressure to supplement this space. The water then sucked in is thrown out by the impeller through the volute and enters the outlet pipe. From this, it can be seen that if the impeller of the centrifugal pump continues to rotate, it can continuously absorb and pressurize water, and water can be continuously lifted from low to high or far. In summary, centrifugal pumps are called centrifugal pumps because they lift water upwards under the centrifugal force generated by
