Metal tube float flowmeter flange type M2S LCD indicator (4-20mA output)

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.

金属浮子流量计根据客户需求可同时标示标准状况流量和具体作业状态的液体流量(根据客户提供、流量、温度、密度、压力等参数由核算机核算完成)亦即可作2-3种刻度标示，输出信号和刻度一同并且线形。导出效仿种类0-10mA,4-20mA或0-20mA，可配频率转化器，输出频率信号并可呈现累计流量。

管路与流量感应器对接有多种形式的结构和规格为便捷规划设计院规划，压根的流量感应器设备高度为250mm，过滤器设备高度为100mm和50mm二中，亦可按客户需求订制。

金属浮子流量计厂家解答一些问题，由于金属浮子流量计的应用十分广泛、不断，因此针对产品的一些知识，才要求金属浮子流量计厂家为应用者详细讲解，当金属浮子流量计应用时，变送器输出存有≤4mAOutput≤4mA状况的一些查询和处理方法。
