又可以称之为智能浮球液位计,是以磁浮球为测量元件，通过磁耦合作用，使传感器内电阻成线性变化，由智能转换器将电阻变化转换成4~20mA标准电流信号，并叠加HART信号输出或就地液晶显示，可现场显示液位的百分比、4~20mA电流及液位值，远传供给控制室可实现液位的自动检测、控制和记录。 Float level transmitter can also be called smart float level gauge. It uses magnetic float as the measuring element. Through the magnetic coupling effect, the internal resistance of the sensor changes linearly. The intelligent changer converts the resistance change into 4 ~ 20mA standard current signal, superimposed with HART signal output or local liquid crystal display, can display liquid level percentage, 4 ~ 20mA current and liquid level value on-site, remote transmission to the control room can realize automatic detection, control and recording of liquid level . This instrument is suitable for petroleum, chemical, power, light industry and pharmaceutical industries, such as sewage treatment and medium level measurement in various atmospheric and pressure vessels, especially for underground tanks and tanks.
的安装：变送器的传感器可垂直、倾倒或水平安装在罐体，槽体等容器设备内，应注意不要让泥沙、沉积物埋没或堵塞膜片。 Float level transmitter installation: The sensor of the transmitter can be installed vertically, horizontally, or horizontally in tanks, tanks and other container equipment. Care should be taken not to bury or block the mud or sediment. In the case of large fluctuations, the sensor should be equipped with an anti-wave tube, that is, a steel pipe is inserted into the liquid, and a number of holes are made at different heights to prevent water waves and eliminate the influence of flowing water pressure. And can fix the sensor. Note: The installation position of the sensor should be 10 cm from the bottom of the liquid to prevent the sediment from blocking the diaphragm. The sensor should be immersed slowly in the liquid, and should not be thrown, so as to avoid unnecessary damage. Except for the sensing lead, the air guide cable is mainly used for atmospheric compensation. Do not clamp it too tightly and bend it excessively to avoid damage to the air duct. The transmitter box should be mounted on a container or a bracket to prevent external force from colliding. The installation position should be convenient for on-site observation and wiring adjustment. The wire hole position of the external transmitter box should be installed downward or horizontally. Do not raise the wire outlet hole to prevent rainwater from entering the transmitter. When the measured medium is unstable, the probe of the cable transmitter is prone to displacement, which affects the measurement accuracy. At this time, it should be fixed.
If the site does not have fixed conditions, a counterweight can be used to increase the weight of the probe and thus stabilize it. If you need to choose a counterweight, please specify when ordering.
