What is Metal Tube Flow Meter?
LZ series metal tube flow meter, also known as metal rotor flowmeter. Metal tube flow meter consists of a measuring tube and side indicator, the field indicator can also be retrofitted with an electric device, suitable for liquid gas, and steam measurement. Stable flow measurement is also possible at high pressures and extreme temperatures.
Metal tube flow meter units are available in a variety of tube sizes and configurations. Metal tube units are available from DN 15 to DN 200.
Metal tube rotameter gives full play to its advantages in small diameter, low flow rate of the medium flow measurement.

Steam can be measured using a metal pipe rotameter. Steam temperatures are above 200 degrees Celsius, and metal pipe rotameter can measure media up to 400 degrees Celsius.
The main measuring element of the glass tube rotameter is a vertically mounted conical glass tube and a float that can move up and down inside.
When the fluid from the bottom up through the conical glass tube, in the float between the upper and lower pressure difference, the float in this differential pressure under the action of rising. When the rising force, the buoyancy force and viscous force on the float is equal to the gravity of the float, the float is in equilibrium position.
Therefore, the flow of fluid through the glass rotameter and the float rise height. That is, there is a certain proportional relationship between the flow area and the glass rotor flowmeter. The float position height can be used as a measure of flow.
The flow detection element of the rotameter is composed of a vertical tapered tube that expands from bottom to top and a float group that moves up and down along the axis of the tapered tube. Below, I will give you a specific introduction to the classification of rotameters.
Glass rotameter:
Glass rotameters are mainly used in various departments such as the chemical industry, petroleum, light industry, medicine, fertilizer, chemical fiber, food, dyes, environmental protection, and scientific research. Used to measure the flow of single-phase non-pulsating (liquid or gas) fluids. The anti-corrosion glass rotor flowmeter is mainly used for the detection of corrosive liquid and gas medium flow. Such as strong acid, strong acid, oxidant, strong oxidizing acid, organic solvent, and other corrosive gas or liquid medium flow detection.
The main parts such as the liquid plastic tube rotameter cone tube are made of AS, ABS plastic. Has relatively good corrosion resistance. The product also has the characteristics of reasonable structure, small size, lightweight, and the tapered tube is not easily broken. The plastic tube rotor flowmeter can be widely used in chemical, environmental protection, food, and other industrial sectors.
Plexiglass rotameter:
Plexiglass rotameter is divided into panel type plexiglass rotameter and pipeline type plexiglass rotameter.
Plexiglass rotameter also has the characteristics of high transparency, intuitive reading, not easy to break, lightweight, long life, and convenient installation and connection. However, the tapered glass tube of plexiglass cannot be used for organic solvents (such as trichloroethylene, dichloroethane).
Metal tube rotameter:
Metal tube rotameter is divided into on-site pointer indication type and remote transmission type.
Metal float flowmeter is a kind of flow measuring instrument commonly used in industrial automation process control. It has the characteristics of small pressure loss, large detection range (range ratio 10:1), and convenient use. It can be used to measure the flow of liquid, gas, and steam. It is especially suitable for medium flow measurement with low flow velocity and small flow.
The metal float flowmeter has a local display type and an intelligent remote transmission type. With pointer display. Instantaneous flow, cumulative flow, liquid crystal display. Upper and lower limit alarm output. Cumulative pulse output, standard two-wire 4-20mA current output, and other forms. Provide users with a very wide choice of space. In addition, the instrument uses a high-quality MCU micro-processing system. Ensure the excellent performance of the flowmeter in various applications.
Float (rotor) flowmeter, also known as rotameter, is mainly used for small and medium diameter flow measurement. Can measure liquid, gas, steam, etc.. Product series specifications are complete, in all walks of life are widely used.
If the flowmeter is divided into 5 categories. Then the five commonly used flowmeters are:
Electromagnetic flowmeter
Differential pressure flowmeter
Turbine flowmeter
Ultrasonic flowmeter
Volumetric flowmeter (PD)
If you want to divide the flow meter into three categories. I think it can be divided into volumetric flowmeters, mass flowmeters, and velocity flowmeters.
