Miniature metal tube float flowmeter (pointer indication)

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.

◆Product execution standard: JB/T6844-2015 (industry standard)

◆General standard of flange: GB/T9115.1-2010 (national standard)

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.

电磁流量计加工带磁浮球液位计和磁浮球液位计的区别：带磁浮球液位计(一般称为磁翻板液位计)关键分成工-种，一种是测装磁翻板液位计,第二种是侧装磁翻板液位计，二种都能够现场显示及带开关导出、4-20m导出等作用;磁浮球液位计分成单浮球、多浮球及带导杆式，单浮球、多浮球为用以开关类控制，带导杆式为摆杆中安装着多个磁簧开关，能导出多点及持续信号，其中持续信号为在摆杆中等间距地安装着若千个磁簧开关(这个间距便是液位计的分辨率)和数量相同的等价电阻，可输出阻抗信号，也可由变送器转化成4-20mA的规范电流信号导出。智能玻璃浮子流量计用于国防、化工、原油、冶金、电力、环保、药业和轻工业等部门的液态、气体压力的测量及自动控制。金属管转子流量计是工业和试验室中常见的一种流量计。
