适用于小口径和低流速介质流量测量;工作可靠,维护量小,寿命长;对于直管段要求不高;较宽的流量比10:1;双行大液晶显示,可选现场瞬时/累计流量显示,可带背光单轴灵敏指示;非接触磁耦合传动;金属转子流量计全金属结构,适于高温、高压和强腐蚀性介质;可用于易燃、易爆危险场合;可选二线制、电池、交流供电方式;多参数标定功能;金属转子流量计带有数据恢复,数据备份及掉电保护功能. Metal float flowmeter is suitable for small-diameter and low-velocity medium flow measurement; reliable work, low maintenance and long life; low requirements for straight pipe sections; wide flow ratio of 10: 1; dual-line large liquid crystal display, optional field Instantaneous / cumulative flow display, with single-axis sensitive indication of backlight; non-contact magnetic coupling transmission; metal rotor flowmeter full metal structure, suitable for high temperature, high pressure and strong corrosive media; can be used in flammable and explosive hazardous situations; can be Choose two-wire system, battery, AC power supply mode; multi-parameter calibration function; metal rotor flow meter with data recovery, data backup and power failure protection functions.

由两个部件组成,转子流量计一件是从下向上逐渐扩大的锥形管;转子流量计另一件是置于锥形管中且可以沿管的中心线上下自由移动的转子。 The metal float flowmeter consists of two parts. One of the rotor flowmeter is a tapered tube that gradually expands from the bottom to the top; the other of the rotor flowmeter is placed in a conical tube and can move freely up and down along the centerline of the tube. Rotor. When measuring the flow rate of a fluid, the flow meter measures the flow of fluid from the lower end of the conical tube. The flow of the fluid impacts the rotor and generates a force on it.

的浮子中间装有导向杆,浮子可以平稳地在导杆上下运行,减小了浮子的跳动。 The metal tube float flowmeter is equipped with a guide rod in the middle of the float. The float can smoothly run up and down the guide rod, which reduces the jump of the float. However, if the guide rod is bent or the float is slightly deformed, the movement will be limited and the reading will not work. The most likely cause is because the valve is quickly opened or closed quickly, which results in the occurrence of air pockets or water hammer, which causes the float to violently impact in the flow meter, which deforms the float or bends the guide rod. The solution is to do it slowly when opening and closing the valve. The second reason is due to the magnetic coupling and the effect. The long-term high temperature or the use environment is too bad, which causes the magnetic coupling and magnetic properties to drop, and the movement of the float cannot drive the pointer's indication. The other is because a lot of iron powder particles are adsorbed inside the metal tube float flowmeter. The solution is to use a magnetic filter in front of the metal tube float flowmeter to filter impurities such as iron filings and iron powder. The third reason is caused by the deformation of the internal structure of the metal tube float flowmeter. The possible reasons are that the mechanical transmission parts such as the pointer gear are stuck, and the float or liner of the PTFE material is deformed. In this case, only the float and lining can be replaced to solve the problem.
