High quality level indicator for tank wholesale manufacturer? Product features: Large display range, wide range of use, suitable for low temperature, medium temperature, high pressure occasions. It can be matched with remote transmitter output 4-20MADC standard signal to realize remote display of liquid level guage. It can also be matched with liquid level switch to realize liquid level control. Generally speaking, the material level feedback is inaccurate and untimely, which is very prone to explosion events, and there is a greater safety risk. Therefore, the requirements for the radar level meter are very high, but the radar level meter often has abnormal material level jumps or falls, or even crashes, resulting in large errors in material level measurement, which brings trouble to production and sales. Read even more information at level indicator for tank.
So what can be done about these difficulties? Under the condition of strong dust, on the one hand, the radar with high transmitting energy can be selected, on the other hand, the measurement software with continuous measurement algorithm of wave-loss waiting can be selected. When the radar encounters strong dust, it will not misjudge the measurement result even if the radar loses wave for a short time. After entering the state of continuous measurement algorithm, if the reflection wave of real material surface can be recognized within the set waiting time, the correct measurement value of material surface can be obtained. In the past, only a few foreign radars have this function. At present, there are also domestic radars with this function, and the practical application effect is very good.
If the radar level meter is unreasonably selected, the interference echo cannot be handled well, and the reliability of the instrument will be reduced. Therefore, the following factors should be considered when selecting a radar level meter: Conductivity and dielectric constant of the measured medium. The measured medium is a conductive liquid or a liquid with a dielectric constant above 4. Generally, a common radar is selected. Liquids with small dielectric constants (dielectric constants below 2) and some conductive solids often use precision radars or guided wave radars due to the large amount of interference echoes.
Mechanical interference, the so-called mechanical interference, means that some components inside the radar level sensor will also vibrate due to the large-scale vibration or impact of the external machine, and even undergo displacement and deformation, which may also cause the pointer of the instrument head to loosen and cause measurement. error. In this case, we usually use spacers, shock springs, etc. to cushion the shock.
Working principle: Working principle of radar level gauge: UHF electromagnetic waves are transmitted to the liquid level of the container under test through the cable or antenna. When the electromagnetic wave touches the liquid level and is reflected back, the instrument detects the time difference between the initial wave and the echo, thereby calculating the liquid level height. Select guided wave radar or airborne radar according to the dielectric constant and measurement length of the measured medium.
So what are the installation technical requirements for radar water level meters? The installation of the radar water level meter must be vertical to the object to be measured; there should be no obstructions between the measured object and the radar water level meter, otherwise it will affect the reflection of radar waves, that is, affect the measurement accuracy; the center of the radar water level meter is far from the shore of the water body. The distance must be greater than the radius of the transmitting beam, otherwise the measurement accuracy will also be affected; the installation cantilever bracket of the radar water level meter must be firm, and cannot be shaken up and down; in order to protect the radar water level meter, the water level meter can be installed on the cantilever bracket. Iron box, put the radar water level meter probe.
