Metal tube float flowmeter flange type M3S LCD indicator (4-20mA output) with explosion isolation

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)

◆Type approval certificate: 2010F449-33

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.

流量计厂家介绍：金属管浮子流量计应用的过程里，可能呈现如标示不对、变送器输出异常等疑惑，而当碰到变送器输出呈现≤4mAOutput≤4mA这类异常时，应用者主要应当根据以下几点来查询：

1、液位传感器是否有被负载状况而毁坏;

2、电源是否有存有疑惑;

3、产品开始所选的量程是否有呈现比实践压力强的状况。智能金属管浮子流量计结构简单工作牢固、准确度高、应用领域广。与玻璃流量计相比可耐较强的压力。

智能金属管浮子流量计适用于小口径和低流速物质流量丈量;工作牢固，维护量小，寿命长;有关直管段要求不高。仪表金属浮子流量计具备就地标示、电远传水表、行程开关警报、耐腐蚀、筒夹型、减振型和防爆等类型。
