Guided Wave Radar vs Differential Pressure Level Transmitter

Guided Wave Radar vs. Differential Pressure Level Transmitter

An application guide courtesy of Tek-Trol Technology Solutions and Hile Controls of Alabama.

Differential Pressure (DP) transmitters can be traced back to the 1950s. Since then they have served as one the most popular technologies for fluid level measurement and have left their mark in process industry. The application range is vast and varies from chemical, petrochemical, and refineries to electric power generation and more. Over the years, Differential Pressure transmitters have single handedly dominated the worldwide market of process level measurement instruments with the largest sales volume.

Guided Wave Radar is a revolutionary method of liquid level measurement in which high-frequency electromagnetic waves are guided to travel from transmitter to the material to be measured. It works on the principle of Time Domain Reflectrometry (TDR).

This application guide provides a comparison between traditional Differential Pressure Level Transmitters and Guided Wave Radars for liquid level measurement applications by analyzing the features and benefits of both.
