Premium level indicator factory? Humidity interference, when the humidity increases, it will cause the insulator resistance to decrease, the dielectric constant to increase, the skeleton to be fluffy, and the resistance to increase, resulting in an increase in leakage current and changes in capacitance and inductance. Also, it softens the colloid and reduces measurement accuracy. Chemical interference, chemical interference usually refers to some corrosive gases, such as acids and alkalis. The long-term action of these gases will not only damage the instrument and internal components, but also conduct electricity with the metal, affecting the normal operation of the radar level transmitter. See even more details on level gauge manufacturers.
For more accurate measurement in deaerators, magnetrol guided wave radar (GWR) is a preferred option. Since its performance and accuracy are not contingent on the specific gravity and/or inference, it can provide reliable measurements in all situations, including the difficult and turbulent process conditions of deaerators and feedwater heaters. In addition, GWR does not require external inputs or calibration to achieve specified performance. This effectively eliminates the introduction of errors during the calibration process or from external sources, i.e., pressure and temperature. With this high level of accuracy, operators can trust that their deaerators will be well controlled.
Secondly, in cement production, material level measurement encountered another difficulty is strong dust interference, especially pneumatic conveying powder silo, dust flying when feeding, low visibility, laser level meter and high energy ultrasonic level meter can not be measured, although radar level meter at this time can receive part of the surface echo. But the echo signal was also weakened. In addition, due to the uneven surface of the radar echo is refracted, will also lead to the existence of radar echo; In addition, there are some conditions from the bottom to the bin inflation, so that the material surface loose, material level measurement is more difficult.
Power supply and output signal, the power supply has 220 V A C, 24 VDC, and the two-wire or four-wire system can be selected according to the needs. Output signal 4 ~ 20 mA DC or digital signal, select the appropriate model according to the needs. The above are all factors that need to be considered when selecting a radar level transmitter. The essence of the details is a serious attitude and a scientific spirit. I hope that every user can choose a suitable radar level meter.
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.

The whole process measurement is rain proof, corrosion proof, high temperature, high pressure, leakage proof, no blind area, eye-catching display, intuitive reading, and a wide measurement range, suitable for all kinds of towers, tanks, tanks, spherical vessels and boilers and other equipment continuous measurement of liquid level. Optional liquid level alarm switch, can realize the upper and lower limit of liquid level alarm and control.
For the ultrasonic instrument that continuously measures the liquid level, when the temperature of the liquid to be measured changes greatly, the change of the propagation speed of the sound wave should be compensated. The connecting cable between the detector and the converter should take anti-electromagnetic interference measures. The structure of the ultrasonic level sensor should be determined according to the process requirements and on-site working conditions.
