Flow meter
DXLZYB electric remote transmission glass tube rotor flowmeter

I. Overview

DXLZYB electric remote transmission glass tube rotor flowmeter is our company's non-linear remote transmission device. DXLZYB electric remote transmission glass tube rotor flowmeter converts the flow signal into an electrical signal. The electric signal is suitable for long distance transmission. This signal is connected to a display recording instrument to achieve the purpose of observing the flow rate of the on-site flow meter in the room or other places. The electrical signal can also be used for automatic control.
DXLZYB electric remote transmission glass tube rotor flowmeter is characterized by stable and reliable electrical signals, not affected by external environmental temperature, humidity and other conditions, no drift.
DXLZYB electric remote transmission glass tube rotor flowmeter is widely used in chemical, petroleum, light industry, medicine, environmental protection, food and metrology testing, scientific research and other departments to measure the flow rate of single-phase non-pulsating fluid (liquid or gas).
DXLZYB / () F / DXLZYJ-() F series corrosion-resistant glass rotor flowmeter has strong corrosion resistance, and can detect the flow of acids (except hydrofluoric acid), alkali, oxidants and other corrosive gases or liquids Suitable for chemical, pharmaceutical, papermaking, wastewater treatment and other industries.

Principles and Structure
The glass rotor flowmeter is mainly composed of a conical glass tube that expands from bottom to top and a float that moves up and down with the flow of the fluid (Figure 3). When the fluid flows through the cone from bottom to top, the lift force S generated by the fluid kinetic energy on the float and the buoyancy A of the fluid rise the float. When the sum of the lift force S and the buoyancy A is equal to the float's own gravity G, the float is in equilibrium and stabilized At a height position, the scale on the cone indicates the flow rate of the fluid.

The cone tube of DXLZYB / DXLZYJ- (F) flowmeter is a smooth inner wall tube (see Figure 4). For flowmeters with a diameter of DN 15 or above, the float moves up and down through the guide rod to maintain stability;

The DXLZYB / DXLZYJ- (F) flowmeter has three guiding ribs on the inner wall of the cone tube to keep the float stable (see Figure 5). Flowmeters with a diameter below DN10 are connected by hoses and equipped with needle-shaped flow regulating valves; flowmeters with a diameter above DN15 are connected by flanges or other connections.
