FA100 type tie rod glass rotor flow meter manual

Project Overview

A type of pull-rod all-stainless steel glass rotor flow meter. It has the characteristics of high sensitivity, wide measurement range, easy use and maintenance. The instrument connection method is flange connection. LZB-FA100 series glass rotor flowmeter is a flowmeter that uses changes in flow cross-section to measure non-turbid, non-pulsating liquid or gas flow under constant pressure conditions.

LZB-FA100 series glass rotor flowmeter is widely used in petroleum, chemical industry, metallurgy, chemical fiber, dye, papermaking, environmental protection equipment, food, sugar refining, and supporting facilities of scientific experimental instruments, etc.

Second Principle and Structure:

The main measuring element of the LZB-FA100 series glass rotor flowmeter is a vertically installed cone with the small end downward and the large end upward. A glass tube (conical tube for short) and a float inside it that can move up and down. When the fluid flows through the tapered tube from bottom to top, a pressure difference is generated between the floats, and the float rises under the action of this pressure difference. When the rising force of the float is equal to the combined force of the gravity, buoyancy force and viscosity force that the float bears, When, the float is in the equilibrium position. Therefore, there is a certain proportional relationship between the flow rate of the fluid flowing through the glass rotameter and the rising height of the float, that is, the fluid area of ​​the meter. The seat height of the float can be used as a measure of flow rate.
