Selection of boiler level gauge

Depending on their size and purpose, boilers typically use at least 2 to 3 liquid level display systems, and the choice of level gauges varies according to different requirements. 1. Direct level display is used to provide the most intuitive way of observing the liquid level; board-type level gauges and two-color level gauges are commonly used for this purpose. On low-pressure boilers with small capacity, magnetic flip-board level gauges are also frequently employed ； 2. Level controllers, which are used for automatic control signals; they typically consist of a balance chamber in combination with a differential pressure transmitter. Immersed float level gauges are also commonly used. Such level gauges require a measurement principle that is directly related to the density of the medium, in order to avoid errors caused by false level readings in boilers ； 3. For safety purposes, electric contact level gauges are commonly used. Their feature is that they indicate the liquid level at individual points, with no connection between these points; thus, if a few of them fail, it does not affect the readings from the other points, giving them extremely high reliability.

It was explained in great detail upstairs. I’ve learned it.*

If you use several differential pressure level gauges not for full-range monitoring but for point checks, they can function just like electrical contacts – without affecting each other – and their reliability is extremely high, so high that it’s almost unbelievable. Do you want to get better at it? This trick isn’t in the textbooks; if you want it, pay the tuition fee – I’ll accept red envelopes through WeChat, hehehe.

For low-pressure boilers, how is the level control achieved using magnetic flap remote control? Is it stable and reliable?

When it comes to \"stability and reliability\", magnetic flap gauges are at least an order of magnitude inferior to differential pressure gauges. Why? Because of the magnetic flap, it is not a static measurement; it is a measuring element that involves displacement and movement. . . The float getting stuck and the flap not flipping are common problems it suffers from. Are there any objections? Whoever objects, step forward – let me show you how I’ll treat you like braised pork, chewing and gnawing until I kill you.

By reliability, and by the level of reliability, what is meant is how long an instrument can operate continuously without any failures There are too many false alarms from the radar; is its reliability high? The readings from the ultrasonic dog fake-death device no longer change – is it reliable? The flip-up large face no longer flips; is it highly reliable? Many factories rely on a large number of staff for operation and maintenance in order to compensate for the insufficient reliability of their equipment. Do you understand? If we’re really talking about unattended operation, true fully automatic control, then many instruments are just good for nothing. .

We use differential pressure transmitters here, one for control and one for reference! 2 sets of differential pressure level gauges.
