Product Details

Overview

The LZDC series metal tube float flowmeter (also known as metal rotor flowmeter) has the characteristics of simple structure, reliable operation, wide applicability, high accuracy, and easy installation. Compared with glass rotor flow meters, this series of flow meters has the characteristics of high pressure resistance, high temperature resistance, strong sense of safety, and concise readings. And it can be applied to flow measurement of opaque and corrosive media. The instrument tube body and flange are made of stainless steel (ICr18Ni9Ti or OCr18Ni12Mo2Ti). The float is made of stainless steel, and the corrosion-resistant float and tube lining are made of polytetrafluoroethylene (PTFE).

Measuring principle

As shown in Figure 1, it consists of two parts: a flow sensor and a flow indicator. The float is vertically installed inside the conical measuring tube and can freely float up and down in the conical tube due to the action of the fluid. There is a high-performance embedded inside the float
Magnetic steel, as the float floats up and down, the magnetic field generated by the magnetic steel around it also changes. When the flow rate tends to stabilize and the float is in dynamic equilibrium, the magnetic field distribution around it also becomes fixed. By mechanically connecting the flow indicator with the conical measuring tube, the magnetic signal of the float can be transmitted in a non-contact manner. In other words, the indicator can detect and process the flow rate value of the fluid through magnetic transmission, and finally indicate the flow rate on the indicator dial through the pointer. At the same time, the LCD also reads the instantaneous and cumulative flow values, and outputs a standard two-wire (4-20) mA signal/HART protocol.
