How to install high frequency radar level meters in different shaped storage tanks

The RD90X series 26G HF radar level has a small antenna size for easy installation; non-contact radar, no wear, and tear, and no contamination. Virtually unaffected by corrosion, foam, atmospheric water vapor, temperature, and pressure changes. Severe dusty environments have little effect on the operation of HF level meters. Shorter wavelengths for better reflection on

What are the areas of application for orifice flow meters?

1. Energy measurement Energy sources are divided into primary energy sources (coal, crude oil, coal bed methane, LPG, and natural gas), secondary energy sources (electricity, coke, artificial gas, refined petroleum products, LPG, steam), and energy-carrying work substances (compressed air, oxygen, nitrogen, hydrogen, water). Energy metering is an important means of scientifically managing energy, achieving energy

The relationship between the transmitting angle of the radar level meter antenna and the diameter and frequency of the Loudspeaker

Smart radar level meters and high-frequency radar level meters are both non-contact measurements where microwave signals are transmitted and received via an antenna. The antenna can be of various types: insulated rod type, conical couch type, and parabolic type. Insulated rod antennas are usually made of polymer materials such as PTFE and polypropylene, which have
