FTQ-1600 Series
Metal Variable-Area (Rotameter) Flow Meter

Working principle of FTQ-1600 metal rotor flow meter:The measured medium flows through the measuring tube from bottom to top, and a differential pressure is generated at the upper and lower ends of the float to form a rising force. When the rising force on the float is greater than the weight of the float immersed in the fluid, the float rises, and the annulus area increases. The flow rate of the fluid in the annular gap decreases rapidly, and the differential pressure between the upper and lower ends of the float decreases. The rising force acting on the float decreases until the rising force balances with the weight of the float immersed in the fluid, and the float stabilizes at a certain position. The height of the float position corresponds to the height of the float being measured. Measure the size of the medium flow rate.
The float has a built-in magnetic steel. When the float moves up and down with the medium, the magnetic field changes with the movement of the float.
A. For the local type, the following magnet in the local indicator is coupled with the magnet in the float to rotate, and at the same time the pointer is driven to indicate the flow rate at this time through the dial.
B. For the intelligent type, the following magnet in the intelligent indicator is coupled with the magnet in the float, causing rotation. At the same time, the sensing magnet and the pointer are driven. A magnetic sensor converts the magnetic field changes into electrical signals. After A/D conversion, digital filtering, temperature compensation, microprocessor processing, D/A output, and LCD liquid crystal to display the instantaneous flow and cumulative flow.
