The remote transmission level gauge is mainly composed of a body, a magnetic float, a pointer, a sensor, and a transmitter. The magnetic float rises and falls with the liquid level, causing the resistance value inside the sensor to change. The change in resistance value is converted into a 4-20mA · DC standard current output through the transmitter, thereby achieving remote display, control, or PID adjustment of the liquid level. Its advantages are high measurement accuracy, simple structure, and easy installation. Suitable for measuring toxic and corrosive liquids and working in high temperature and high pressure environments.

Equipped with a remote liquid level gaugeWhen used on site, various phenomena may occur, such as the inability to flip the plate on site, the inability to transmit remote signals, and the failure of secondary instruments to display. These ultimately depend on the float of the local level gauge cylinder, as only it senses these external components to operate.

The on-site magnetic flap level gauge showed no liquid level display, but the liquid level display device transmitted remotely to the control room showed normal display. What is the reason for this? Judging from this phenomenon, it is highly likely that the flip column inside the flip indicator of the on-site magnetic flip level gauge is damaged.

So users will ask: Is it possible that the float is broken and lacks magnetism.

The flap of the on-site flap level gauge is not moving. The liquid level gauge is blocked. That means the float doesn't move anymore. The remote liquid level gauge indicates normally. Why is that? Isn't the remote liquid level gauge transmitting electrical signals through the up and down movement of the float?

And we should tell users like this: they won't. Due to the fact that the remote transmission part of the magnetic flap level gauge also transmits signals through the magnetic properties of the float, if the magnetic properties of the float weaken, there will be problems with both on-site indication and remote transmission display. And your remote liquid level indicator has liquid level display.

Therefore, the flip column inside the flip indicator of the on-site magnetic flip level gauge was damaged.
