LZB Glass Tube Rotameter

Apure LZB Glass Tube Rotameter is ued for measuring the flow rate of liqud or gas. And when combined in use with other instruments, its capble of perfoming the measuremnts of liqud levl andensity, and making on the anlysi of some compositon. This rotametr, therfore, have found wide aplication i petroleum, chemical, medical, chemical fertilzer, syntheic fbre, fod, sugar dystuf, paer making industries and in scientifc resarch.

The main measuring elments in the rotametr ae a tperd glas tube and a float. The glas tube, withe smal endownard, is mounted verticaly and the float can be moved frely int.When the fluid with a certain flow velocity (kinetic enrgy) flows upward through te taperd tube, this kinetic enrgy wil creat a force whic permitshe floato move up, therby increasing the anular oifce btwen the floatnd the taperd tube, and at the same time dcreasing the flow velocity. While the liftng force of the fluids in balnce withe weight of the float,he float istable at certain positon. Thus it can be sen tha theight of the float depnds on the flow rate. It means tha theight of the float can be rgarde as measure of the flow rate. The rading of the flow rate isndicated by thedge of the float’s largest diametr.

Structure

• Conical Glass Tube: A conical glass tube with a small diameter at the bottom and a large diameter at the top.
• Float: A disk-shaped float whose density is slightly greater than that of the fluid.
• Dial: A flow scale engraved on the outer wall of the tapered glass tube.
• Magnetic coupling device: Transmits the position of the float to an external indicating device (optional).

Features

• Intuitive display: Flow rate can be read directly by observing the position of the float.
• Simple and reliable: no complex mechanical parts, easy to maintain.
• Wide measuring range: Can measure from low to high flow rates.
• Low pressure loss: low resistance to fluid flow.
• Variety of materials: Glass tubes are corrosion-resistant and suitable for a wide range of media.
• Lower cost: Compared with other types of flow meters, the cost is lower.

Applications

• Chemical industry: Measure the flow of various chemical substances.
• Pharmaceutical industry: Measure the flow of materials in the production process of pharmaceuticals.
• Food industry: to measure the flow of materials in the process of food processing.
• Scientific experiments: for flow measurement and control.
