Description
Technical Field
The invention relates to the technical field of novel liquid level meters, in particular to an explosion-proof type 26GHZ radar liquid level meter convenient to install.
Background
The radar level gauge belongs to a general radar level gauge, and is a measuring instrument based on a time travel principle, wherein radar waves run at the speed of light, and the running time can be converted into a level signal through electronic components. The probe emits high-frequency pulses which are transmitted in space at the speed of light, and when the pulses meet the surface of the material, the pulses are reflected back to be received by a receiver in the instrument and convert distance signals into level signals.
The radar level gauge transmits very short microwave pulses of very low energy which are transmitted and received via the antenna system. The radar wave runs at the speed of light. The operating time can be converted into a fill-level signal by the electronic component. A special time extension method ensures stable and accurate measurement in a very short time. Even if the working condition is complicated, false echo exists, and the echo of the material level can be accurately analyzed by using the latest microprocessing technology and debugging software.
When current radar level gauge was installed on the container, generally used the flange to fix, though the leakproofness of container has been effectually guaranteed to this kind of mode, the installation is inconvenient, and when overhauing and maintaining the radar level gauge, dismantles the difficulty, especially the longer radar level gauge of service life, and its fastening screw has mostly embroidered and dies, and this brings very big trouble for the staff, so we have proposed the explosion-proof type 26GHZ radar level gauge convenient to installation.
