Product Introduction
Product Introduction
The metal tube float flowmeter is a flow measurement device based on the variable area principle. Its core consists of a metal conical tube, a float, a positioning rod, and an indicator. When the fluid flows upward through the conical tube, it pushes the float up. The position of the float changes with the flow rate (the greater the flow rate, the higher the float), and this position is converted into a flow reading through magnetic coupling or mechanical transmission. It is widely used in industries such as petroleum, chemical engineering, metallurgy, and medicine, and can measure the flow of liquids, gases, and steam, etc. It is suitable for medium and low flow rates and medium-sized pipe diameters (DN15-DN200), and is particularly suitable for the measurement of corrosive or fluids with certain pressure.

Product Principle
It consists of two parts: a flow sensor and a flow indicator. The float is vertically installed in the conical measuring tube. Due to the action of the fluid, it can freely float up and down in the conical tube. Inside the float, there is a high-performance permanent magnet steel. When the float moves up and down, the magnetic field around the magnet steel will change. When the flow tends to be stable and the float is in dynamic balance, the magnetic field distribution will also be stable. Through the flow indicator mechanically connected to the conical measuring tube, the magnetic signal of the float is transmitted in a non-contact manner, and then the flow value is detected and processed in a magnetic transmission manner. Finally, the flow value is displayed on the indicator scale, while the LCD displays the instantaneous and cumulative flow values, and outputs a standard two-wire (4 - 20) mA signal / HART protocol.

Product features
·Stability in measurement: The variable area measurement principle has strong anti-interference ability and is less affected by changes in medium viscosity and density. The measurement error is ≤ ±2.5%
·High durability: The metal tube (stainless steel, Hastelloy alloy) and corrosion-resistant float design can withstand a pressure of up to 40 MPa and a temperature range of -80℃ to 400℃. The service life is long.
·Easy installation: It supports vertical and horizontal installation, and no straight pipe section is required. It can be paired with a pointer, LCD display or remote transmission module (4-20). ·Simple maintenance: No complex internal components. When the float gets clogged, it can be easily disassembled and cleaned. No frequent calibration is required on a daily basis.
