Level meter classification and fault summary

Level meter definition:

Level gauges are used in many industrial or civil applications where it is necessary to monitor the level of open or closed windows or level of natural water flow. We will normally call the level of the liquid medium in the window. The level of solid or particulate matter in the window The procedure is called the material level. The instrument for measuring the liquid level is called the liquid level gauge, and the instrument for measuring the liquid level is called the bit gauge. The instrument for measuring the interface between the two surfaces and the three kinds of cutters is different in density, and the interface of the liquid medium is not called the interface meter. The instrument is collectively referred to as level gauge ultrasonic level meter (ultrasonic level gauge) which is a type of low level meter. The main point of the base is non-contact measurement. The level meter not only has high precision, high stability, good temperature The compensation effect also has the advantages of waterproof performance, light weight and small size, etc. It has strong anti-interference ability and can completely solve the problem of condensation. The valve body of the liquid level instrument is cast with cast iron, ductile iron, carbon steel, alloy steel, stainless steel, copper and other materials, and can also be smelted and manufactured according to the special needs of users. Widely used in water conservancy, construction, fire control, electric power, environmental protection, petroleum, chemical and other fields.

Level meter classification:

Liquid level meters mainly include float level gauges, buoyancy level gauges, float level controllers, magnetic flap level gauges, ultrasonic level gauges, wireless ultrasonic level gauges, and high protection level gauges. In addition to specialized level gauges, level meters can also measure the level. Commonly used level switches mainly include tuning fork level switches, RF admittance level switches, cable level switches, split level switches, level gauges, radar level gauges, etc.

Level gauge fault judgment and solution:

1. Check whether the power supply is connected correctly. If it is found that the connection is incorrect, it should be modified according to the operation manual.

2. Measure the voltage between +24V and O/P with a tri-voltage meter. The voltage should be between 13V~36V. If the voltage is abnormal, you should check whether the line or related equipment is abnormal.

3. The second item should be confirmed after normal, and then in the 4 ~ 20MA loop string a milliampere meter, check the current is normal, if the current value is not normal should replace new products or contact customer service staff

4. Check the voltage between IN and COM with a voltmeter. Normally it should be about 2.5V. If the voltage is too low, you should remove the EXC wire. If the voltage returns to normal, it indicates that the magnetic yellow module is abnormal, if the power is still low It means that the signal converter is damaged. If you find the above phenomenon, you should replace the signal converter or contact customer service personnel according to the actual situation.
