How to calculate the output of the metering pump?
For more details, please contact winny: [email protected] How to look at the size of the melt metering pump and how to calculate the output of the metering pump? The size of the melt metering pump can be expressed in terms of displacement. That is, the gear of the melt metering pump. The volume discharged per revolution is generally expressed in cc. There are various metering pump specifications such as 20cc, 31.5cc, 50cc, 100cc, 150cc, 200cc, and 250cc.

types of liquid flow meters
[email protected] Advantages of vortex flowmeter: vortex flowmeter has no moving parts, the measuring element has a simple structure, reliable performance, long service life and high accuracy; Disadvantages of vortex flowmeter: poor adaptability to measuring dirty media, high requirements for straight pipe sections, and poor anti-vibration performance. Turbine flow meter Turbine flowmeter is a kind of velocity flowmeter, which uses gas to drive the impeller of the flowmeter to rotate, and the speed of the impeller rotation is proportional to the volume flow of the fluid. The flow rate is proportional to the pulse signal, the flow rate of the liquid is obtained after calculation, and then the flow rate of the pipe is calculated according to the cross-sectional area of the pipe.

Flow meter installation precautions
[email protected] Installation problems have different requirements for flow meters of different principles. For some flowmeters, such as differential pressure flowmeters and velocity flowmeters, according to regulations, a certain length or a long straight pipe section should be equipped upstream and downstream of the flowmeter to ensure that the fluid flow before the inlet end of the flowmeter is fully developed. . While other flowmeters, such as positive displacement flowmeters, float flowmeters, etc., have no or lower requirements on the length of straight pipe sections.

electromagnetic flow meter installation requirements
magnetic flow meter are divided into plug-in electromagnetic flowmeters and pipeline electromagnetic flowmeters. Pipeline electromagnetic flowmeters and insertion electromagnetic flowmeters have the same installation requirements and different places. In total, there are requirements for the external environment and installation methods.

What are the factors affecting the accuracy of vortex flow meter?
[email protected] Vortex flow meters are mainly used for flow measurement of medium fluids in industrial pipelines, such as gas, liquid, steam and other media. It is characterized by small pressure loss, large measuring range and high precision. When measuring volume flow under operating conditions, it is virtually unaffected by parameters such as fluid density, pressure and temperature. There are no moving mechanical parts
