The electrical principle of magnetic float flowmeter
Principle: water, air, liquid, or gaseous chemical medium, vertically upward, passing through a flowmeter. The float is held up by fluid power, and the flow rate is displayed directly on the measuring scale of the measuring tube through the reading edge at the top of the float.The float flowmeter is a volumetric flow meter, also called a rotor flowmeter, in which the float moves up and down with the flow rate in the vertical cone tube and changes the flow area between them.In the United States and Japan, it is often referred to as Flowmeter Area (Variable) or area flowmeter. The principle of the float flowmeter was conceived in 1860s, and the actual commodity appeared in 20. From the proportion of the application table, in 1985, the British survey, 72 enterprises, 17000 flow meters, floater 19.2%. The output of float meter in China is estimated to be between 150 thousand -17 and 10000 units in 1996, of which about 95% is glass tube float flowmeter.
I'm a flowmeterRotameter (output switch signal, 4 - 20mA with digital signal)Caliber: DN10-DN65Flow range: Minimum 3 l/h, maximum 50000 l/hMaterial: UPVC PA PSU PVDF | | |Model: DFM165 DFM170 DFM200 DFM350 | | |Work stress (Mpa):10bar;How it works: water, air, liquid or gaseous chemical medium is vertically upward and downward through the flow meter. The float is held up by fluid power, and the flow rate is displayed directly on the scale of the measuring tube through the reading edge at the top of the floatThis flowmeter is a magnetic float meter. It is compatible with a bistable limit switch or a flow sensor. The switch and closing of the limit switch can be automatically adjusted
The electrical principle of magnetic float flowmeter:In the measuring tube, the float moves upward as the flow rate changes. At one point the buoyancy of the float is balanced with the gravity of the float. At this point, the float and the orifice (or cone) between the circulation of the ring gap area to maintain a certain. Rising annulus area and float height is proportional to the float in the measuring tube up position represents the size of the flow indicator changes the float position by the internal magnet transmission to the outside, to correctly indicate the flow indicator value. This allows the indicator housing to be in direct contact with the measuring tube. Therefore, the instrument can be used for high temperature and high pressure operating conditions, even if a limit switch or transmitter is installed.
