This document provides a guideline for choosing and installing Rosemount™ Process radar devices in stilling wells and bypass chambers.
Even though process radars generally provide robust operation installed in still pipes, all process radars regardless of make or type are designed to perform at their very best during free propagation. Installed in still pipes, the process radar’s accuracy may be affected due to the microwave propagation through the still pipe. For highest accuracy in still pipes, we have developed the Rosemount 5900 Radar Level Gauges with unique array antennas utilizing a low-loss microwave mode dedicated for still pipes. Refer to Rosemount 5900S Radar Level Gauge Product Data Sheet and Rosemount 5900C Radar Level Gauge Product Data Sheet for more information.
Stilling wells and bypass chambers are used in many applications and many different types of tanks and vessels. The two installation methods will jointly be referred to as pipes. Radar transmitters can be used in these installations, but function differently in pipes than in normal vessel installations. This guide is intended to assist with radar device selection and installation for optimal performance.
