Chemical Air Water Glass Tube Low Flow Rotameter Plastic Tube Stainless Steel
Description
LZB glass rotor flowmeter is a commonly used instrument used to measure the instantaneous flow of fluids (liquid, gas). It is suitable for measuring the flow rate of transparent fluids, suitable for measuring medium with low pressure and low temperature. It is widely used in chemical, food, environmental protection, metallurgy, machinery, pharmaceutical and other industries as well as scientific research departments to measure single-phase non-pulsating fluids (liquid or gas). ) flow rate, the small-diameter glass rotor is particularly suitable for liquid sampling and gas sampling.
The LZB glass rotor flowmeter is equipped with a float (rotor) that can move up and down in a vertical transparent cone tube. When the liquid flows through the cone tube from bottom to top, it is throttled by the float, creating a differential pressure between the upstream and downstream of the float. , the float rises under the action of this differential pressure. When the force that causes the float to rise is equal to the combined force of gravity, float and viscosity force, the float is at the equilibrium position. Therefore, the fluid flow rate flowing through the flow meter is equal to the rising height of the float, that is, the same as the height of the flow meter. There is a certain proportional relationship between the flow areas, and the position and height of the float can be used as a flow measurement.
They are mainly composed of tapered glass tubes, floats, upper and lower bases, upper and lower stops, support plates, outer covers, sealing rings, etc. For flowmeters with a diameter of less than 10 mm, pipe (soft or hard) connections are used and can be equipped with There is a flow regulating valve. For flowmeters with diameters above 15 mm, use flange connection (JB78-59 cast iron flange).
