Float level gauge is a commonly used level gauge, suitable for petroleum, chemical, electric power and other fields. However, there is still very little knowledge about float level gauges. Now, let’s take a look at what happens when the float level gauge is broken with Hokoda’s instrument.What to do if the float level gauge is brokenFault one, the indication is not normalThe indication of the float level gauge is abnormal, which is a very common fault of the float level gauge. This failure phenomenon may be caused by the ball falling off, the ball connecting rod is broken, the ball switching mechanism is damaged, the ball pointer and the head are damaged. Measure the circuit voltage. If there is no signal, the polarity of the primary component’s power supply is not reversed, and the current conversion part has no current output, it means that the meter header is damaged, and it corresponds to the replacement of the floating level meter header.2. Interfered by the magnetic fieldWhen the float level gauge malfunctions, from the analysis of the working principle of the float level gauge, most of it is due to the interference of the magnetic field. Since the float and the guide rail of the float level gauge contain magnetic bodies, if they are interfered by other magnetic fields in the use environment, it will also affect the normal operation of the instrument, and even cause the demagnetization of instrument parts. Please confirm whether there is a strong magnetic field around the meter and the container, and whether there are magnetic impurities in the liquid to be measured. When there is a magnetic field, in order to avoid the abnormality of the floating ball level gauge caused by the interference of the magnetic field, please clear it quickly.Trouble three, float on the baitThe floating ball usually gets stuck because the liquid to be measured contains impurities and dirt. After a period of time, the guide rod will slowly become fouled. If the floating ball is not moved by the owner, the meter will not output a signal. If the ball is stuck, the instrument staff must immediately observe the state of the ball, check whether the surface of the guide rod has condensed scale, and clean it up as soon as possible. Especially for the tested liquid containing impurities, the instrument staff should clean the instrument rails on a regular basis.What to do if the float level gauge is brokenWhat is a float level gaugeThe float level gauge uses a magnetic levitation ball as the measuring element, and the resistance in the sensor changes linearly through magnetic coupling. The resistance change is converted into a 4-20mA standard current signal through an intelligent converter, and the percentage of the liquid level, 4~ 20mA current and liquid level value, remotely supplied to the control room. This instrument is suitable for sewage treatment in petroleum, chemical, electric power, light industry, medicine and other industries and the measurement of medium level in various atmospheric and pressure vessels, especially for underground Liquid level measurement of storage tanks and oil storage tanks. The float level gauge is composed of float, plunger and so on. The float level gauge is installed on the ceiling of the container through a connecting flange, and the float floats on the liquid surface according to the principle of equal volume of discharged liquid. When the liquid level of the container changes, the float also moves up and down. Through the magnetic action, the dry spring of the float level gauge is magnetically absorbed, so that the liquid level position is changed into an electrical signal. The actual position of the liquid is displayed digitally by the display instrument. Remote detection and control of liquid level. The most basic use of float level gauges is liquid level measurement. After reading the introduction of the editor, I think you know how to deal with the broken float level gauge.
