Clamp type food / medical special flowmeter

Overview.

LZ series metal tube float flowmeter (also known as metal rotor flowmeter) is a variable area flowmeter, with simple structure, reliable work, wide range of applications, high accuracy, easy installation and so on. The series flowmeter and glass float flowmeter comparison, with high pressure, high temperature, strong sense of security, according to the flow output of 4 ~ 20mA current signal can be used for automatic detection and control, etc.. And can be applied to opaque media and corrosive media flow measurement. The two series are divided into field indication type and field indication with electricity remote transmission type.

Metal tube float flowmeter is composed of measuring tube body, orifice plate and float (cone tube and float) and magnetic conversion instrument. According to the installation method can be divided into vertical basic type, horizontal type; according to the connection method is divided into flange type, thread type and clamp type, which corresponds to the caliber of the flow range and the same basic performance. The series flange vertical type can be lined with PTFE or F46 corrosion resistant type.

The working parameters of this series instrument and its conversion and correction are provided by the instrument calculation software with standard calculation methods to ensure the accuracy and measurement reliability of the instrument.

Working principle.

LZ series metal tube float flowmeter for variable area flowmeter, that is, in the vertical measuring tube of the flowmeter, when the fluid flows upward through the tube, the float moves upward, at a certain position the lift force on the float and the float gravity to reach a balance, at this time the float and the orifice plate (or cone tube) between the circulation ring gap area to maintain a certain.

The ring gap area is proportional to the float's rise height, i.e. a certain height of the float represents the size of the flow. When the float moves up and down, the position is transferred to the external indicator in the form of magnetic coupling, so that the pointer of the indicator follows the float movement and indicates the flow rate on the dial. The electric remote transmission type is to indicate the flow rate on the spot with the pointer and then convert the flow rate value into a standard 4-20mA signal accurately through the angular displacement sensor or electric transmission circuit.

选用优质电磁流量计磁场和进口电子元件，使商品具备：构造简易、使用方便、性能稳定、使用寿命长、便于安装维护等优势。磁浮球液位计有别于其他浮球液位计的构造关键区别在于这是基于浮力和静磁场原理设计生产的。带有磁铁的浮球（简称浮球）在待测物质里的位置受浮力功效影响：液位的转变造成带磁浮球位置的变化。

磁浮球液位计原理：浮球里的磁场和感应器（磁簧开关）功效，涡街流量计加工使串连入电路的元件（如定值电阻）的数量发生变化，进而使仪表电控系统的热学量发生变化。也就是使带磁浮球位置的变化引起电学量的转变。根据检验电学量的转变来反映器皿内液位的状况。该仪表能直接输出阻抗值信号，还可以配合R-I转化器，导出电流值（4～20mA）信号；同时配合其他转化器，输出电压信号以及开关信号。进而完成电信号的远程传输与控制。
