The radar level gauge is a kind of widely used level gauge, and the radar level gauge must be installed in strict accordance with the requirements. Does the on-site installation of the radar level gauge require compression? What are the specific installation requirements?Do I need to put pressure on the on-site settings of the radar level gauge?Do I need to put pressure on the on-site settings of the radar level gauge?The installation of the radar level gauge does not require on-site compression. The installation of radar liquid level timer must avoid the supply port, supply curtain, and vortex. This is because when the liquid is injected, a false echo that is much larger than the effective echo reflected by the measured liquid surface will be generated. At the same time, the irregular liquid level caused by the vortex will scatter the microwave signal and cause the attenuation of the effective signal. Avoid these. For containers with agitators, do not install the radar level gauge near the agitator. Because irregular eddy currents are generated during stirring, which leads to the attenuation of radar signals. At the same time, the stirrer blades bring false echoes to the microwave signal, especially when the relative dielectric constant of the measured object is small and the liquid level is low, the influence of the stirrer is more serious. When using a radar level gauge to measure the level of corrosive and crystalline objects, in order to prevent the influence of the medium on the sensor, the manufacturing plant generally adopts a PTFE measuring window and a separation flange structure. The temperature of these parts cannot be too high. The temperature of PTFE is 200.Do I need to put pressure on the on-site settings of the radar level gauge?What are the specific installation requirements1. When setting up in the open air, in order to avoid measurement errors caused by water on the probe line in rainy weather, the probe line should not be exposed out of the container.2. The stainless steel process connection parts at the lower part of the casing or junction box must be reliably connected (grounded) to the outer wall of the vessel, and the contact resistance shall not exceed 2.3. During normal operation, the probe line must not have a large swing in the container. Otherwise, the signal will become unstable.4. The probe line should be as far away as possible from the inner wall of the container to avoid distance5. For single-wire software probes, the excess part can be pulled out through the upper end of the process coupling and then cut off, and then tighten the deposit bolts. On the other hand, for the twisted-pair probe, the excess part can be wound on the liquid level to be measured. It is not allowed to wind the excess part on the bottom of the container, nor is it allowed to be wound on the effective measuring section.Many people want to know whether the on-site setting of the radar level gauge requires compression. According to the editor, the installation of radar level timing does not require on-site compression.
