What is a magnetic flap level meter with remote transmission?

Project Overview

What is the working principle of the magnetic flap level gauge with remote transmission? For those who need to choose a liquid level meter, this is a question worth knowing. This article mainly explains this issue.

Magnetic flap level gauge mainly adopts two forms: magnetic coupling principle and buoyancy principle. When it is in normal operation, the magnetic float in the magnetic flip plate will float up and down as the liquid being measured rises and falls. The magnetic steel inside the float drives the magnetic flip column on the panel, and under the action of the magnetic coupling principle, it The internal flipping column flips and changes. Two colors can be used to distinguish the movement of the flipping column. When the color of the flipping column changes from white to red, it indicates that the medium liquid level is rising. When the color of the flipping column changes from red to white, it means that the liquid level of the medium is rising.

The actual liquid level can be determined through the junction of red and white colors, which is convenient for staff to observe. The magnetic flap liquid level gauge and the WCY-UK bundled liquid level switch can be used for remote transmission monitoring. The liquid level switch is close to the main tube of the magnetic liquid level gauge and is in the same magnetic field as the magnetic liquid level gauge. The magnetic field force of the magnetic float of the liquid level gauge is used to drive the opening and closing of the liquid level switch to achieve the purpose of automatic monitoring. The WCY-UK liquid level switch can cooperate with external circuits or DCS or PLC to realize remote monitoring and alarm of liquid level.

Characteristics of magnetic flap level gauge

There are many methods and types of instruments for measuring liquid level. Here, the more commonly used hydrostatic method is used for liquid level measurement. Instruments for comparison. When using a differential pressure transmitter to measure liquid level using the static pressure principle, the density of the measured medium and the negative migration of the gas phase must be considered. When the actual working conditions put the medium in a critical boiling state, its density is a variable; or when the concentration of a mixed liquid composed of several components changes, the density will also change accordingly; when negative migration is not used, liquid accumulates in the gas phase pressure tube , or negative migration is used, and errors will occur when the liquid in the liquid cylinder evaporates or is lost.

The occurrence of these errors is unpredictable in time and is not fixed in value. Sometimes the error percentage can be as large as more than 2 digits. The liquid level measured by the LB liquid level transmitter is not affected by the density of the medium, and there is no negative migration problem. The error is fixed at ±10mm, which is slightly larger for a small-range liquid level measurement system (such as the range of 0 to 500mm). , about ±2%, but its error is fixed. For a wide range of liquid level measurement, the error is very small. For example, for 0~2m, the error is ±0.5%. 5.2 Workload A magnetic flap liquid level gauge and a differential pressure transmitter require 4 flanges to install, but this system only needs 2 flanges. At the same time, it requires fewer holes in the equipment, which is beneficial to the equipment. At the same time, the inconvenience caused to process personnel by inconsistent liquid level percentage readings of the two types of liquid level gauges due to inconsistent source positions of the magnetic flap liquid level gauge and the differential pressure transmitter is eliminated. Adjustment and routine maintenance are easy.

Magnetic flap level gauges are used in chemical raw material liquids, oil products, and high-temperature pressure liquid level measurements. The outstanding features are stability, on-site display, remote transmission display, high and lowLevel switch output, if a fault occurs, you can quickly know, which can reduce the embarrassment of installing multiple liquid level gauges in each storage tank, and also save costs.
