Metal tube float flowmeter flange type M4 indicator

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.

因为在不均匀压力的功效下，PTFE会形变，因此法兰螺帽匀称扭紧对称；·含有液晶显示的仪表，安装时要尽量避免阳光直射显示屏，以防减少液晶使用期限；含有锂电池供电的仪表，安装时要尽量避免阳光直射、高温环境（≥65℃）以防减少锂电池的容积和寿命。

随着仪表设备的不断发展，金属管浮子流量计在行业中得到了快速地发展，金属管浮子流量计针对如今的人们而言，早已不再陌生了，毕竟在许多行业中都会应用到不同的流量计，可是金属管浮子流量计的应用还是没有多少。很多人了解其他的流量计，可是针对金属管浮子流量计的的了解却不多。因而想要更多的人了解金属管浮子流量计，是要时候取得进步，让大量的人了解它。本类故障在金属浮子流量计原始装用调试时就出现，但一经改善排除故障，之后在相同条件下一般就不会再度出现。
