Interface level gauge

RF admittance interface analyzer, definitely

Admittance level gauge (Guided Wave Radar, GWR): The GWR level gauge uses microwave pulses that travel along waveguide wires toward the bottom of the tank, and it measures the liquid level and interfaces by analyzing the reflected signals. It features high accuracy, simple on-site installation and debugging, and is suitable for various media and environmental conditions. Recommended product model: Rockwell Autonik Sitrans LG200. Ultrasonic level gauge: By emitting and receiving ultrasonic pulses, it calculates the liquid level or interface using the time difference and the sound speed of the medium. Ultrasonic level gauges perform non-contact measurement, are not affected by medium concentration or bubbles, and are widely used for measuring various liquids and solid materials. Recommended product model: Emerson Rosemount 3300 series. Amplifier-type float level gauge (Magnetostrictive Level Transmitter): Determines the position of the liquid interface by measuring changes in magnetic field strength. It features high accuracy and stability, and is suitable for various media and environmental conditions. Recommended product model: ABB LMT100. Differential pressure level gauge: It calculates the liquid level and interface by measuring the pressure difference between the bottom and top of the liquid in the tank. Its accuracy is greatly affected by process conditions such as temperature and pressure, but due to its low cost and ease of maintenance, it is still widely used in industries such as the chemical industry. Recommended product model: Honeywell STD700 series.

1. For changes in total liquid level and large density differences, dual float magnetostrictive technology can be used. 2. For full liquid levels and large total distances (large density difference), a double-flange (or ERS level gauge) can be used. 3. There is another method, guided wave radar. Recommend 1.3.
