Flow conversion of metal tube float flowmeter
Metal tube float flowmeter (also called metal rotor flowmeter) is used to continuously measure the volume flow of liquid and gas in closed pipelines. It is simple in structure, reliable in operation, convenient to use and maintain, and can adapt to various occasions. Therefore, it is widely used in flow measurement. And industrial process control.
The metal tube float flowmeter is composed of sensors and indicators. In addition to indicating the instantaneous flow rate on the spot, it can also transmit 4~20mADC electrical signals. The whole module adopts modular combination design, which can quickly increase the upper and lower limit switches and flow accumulation function in the field. Each functional unit board is a plug-in structure, and has the characteristics of simple, convenient, and accurate replacement parts.
Flow conversion of metal tube float flowmeter. The flowmeter manufacturer uses water or air for calibration of the float flowmeter. Due to the different state and timing of the medium during actual application, according to the measurement principle, the flow value and the calibration time represented by the float at the same position in the measuring tube are different. To correctly select the specifications of the flow meter and use the instrument on site, It is necessary to know the flow conversion relationship between them.
In addition, the industry standard of the float flowmeter stipulates that its accuracy is relative to the full scale. Therefore, when the user uses it, the common flow rate should be 60%~80% of the full scale, which is reasonable. If used below 50%, the relative error will be Increased, the accuracy is affected. If the flow rate exceeds the full scale, it is impossible to measure normally. Therefore, only the correct flow conversion can select the appropriate meter.
