Metal tube rotameter measured medium flows through the annulus space between measuring tapper pipe and float from bottom to top, producing differential pressure on the top and bottom of float to form lifting force. When the lifting force on float is stronger than the weight of float in the fluid, the float will rise, annulus area will also increase. The flow rate of fluid at annulus space will suddenly decrease, the differential pressure on top and bottom of float decreases, the lifting force on the float also decrease till lifting force and the weight of float keep balance, float will stay at a location. The height of float is the flow of measured medium. There’s magnetic steel in the float, while float moves up and down with medium, magnetic field will change with the movement of float.
Product Feature
1. Metal tube rotameter has simple structure, good stability and reliability.
2. Independent of medium’s physical and chemical states such as conductivity, dielectric constants, etc.
3. Applicable for all kinds of medium environment such as corrosive, toxic and explosive one.
4. Interface measurement or level measurement of 2 kinds of medium with different density.
5.Two-wire 4~20mADC signal output, 0.8’’ or 0.56” LED digital display.
Applications
Due to its unique advantages, this flow meter is widely used in the fields of petroleum, chemical industry, steel, light industry, sewage processing, environmental protection, water conservancy project and pharmacy to measure the volume flow of the conducted liquid mediums, such as acid, alkali, salt solution and so on.
