Products Information 
 

                                        Features
Instruments are safe, clean, precise, long life, stable and reliable, Easy installation and maintenance And other characteristics, i.e. Suitable for acid, alkali, salt, antiseptic, high temperature and other fields. It can be connected to display meters, PLC and various DCS systems through 4 ~ 20mA to provide real-time liquid level data for industrial automation operation. The instrument circuit selects high-quality power components from the power supply part, selects imported highly stable and reliable devices, and can completely replace the same type of foreign imported instruments; the acoustic intelligent technology software can perform intelligent echo analysis without any debugging and other special steps. This technology has the function of dynamic thinking and dynamic analysis, so that the accuracy of the instrument is greatly improved, the liquid level accuracy reaches ± 0.25%, and it can resist various interference waves. Non-contact instruments, which do not come into direct contact with liquids, have a low failure rate. Instrumentation provides a variety of installation methods, and users can completely calibrate the instrument through this manual. All the input and output lines of the instrument have the protection function of lightning protection and short-circuit protection

Installation Guide 
 

In the open environment, the bracket installation method is generally used, and the instrument is provided with a spiral ring to fix it. Or directly open a circular hole with a diameter of 60 mm at the installation position on the top of the tank or the lid, put the meter in, and then tighten the screw ring from the bottom to the top. The installation must ensure that the probe surface of the instrument is level with the measured liquid surface. As shown in the right figure, the probe of the instrument hits the liquid level and reflects back to the probe. After the probe receives it, it calculates the time from the wave to the wave to obtain the measurement space H. The installation height TH of the instrument minus the measurement space H will be Get the current level L. Meter range refers to the distance that the meter can measure. The installation height TH should be less than the range. The instrument blind zone refers to the area where the meter cannot measure near the probe. The distance between the highest liquid level and the probe should be greater than the blind zone. For example, the blind zone is 0.5m, then the distance between the highest liquid level and the probe must be greater than 0.5m. Such as: measuring range: 6 meters, blind zone: 0.45 meters, the actual measured maximum liquid level is: 0 ~ 5.55 meters.The wave propagation of the probe is a diffusion process, that is, there is a directional angle. Pay attention when installing, otherwise it may hit the protrusions of the pool wall or the edge of the channel
