The QTS Guided Wave Radar delivers an independent reading of liquid and solid levels. These top mount, direct insertion radars measure interface and direct level of liquids and solids, both of high and low pressures and temperatures.
Modern Boiler Level
Eliminate Water Density Errors
The Questtec LT-430 provides an exclusive means of achieving accuracy with Guided Wave Radar when used in a water column to determine level in a high pressure steam system. The LT-430 utilizes the data collected from at least 4 thermocouples installed on the water column and determines an actual average water temperature. The primary loop is dynamically corrected and a secondary loop is communicated to any device included in the loop.

Bypass Chamber
The Questtec ByPass Chamber is a chamber for level transmitters. It is the ideal solution for level measurement in difficult process conditions, e.g. turbulence and foam. In this way, the bypass chamber ensures the best installation conditions for reliable and accurate readings of different types of level transmitters like guided radars and non-contact radars. These can just be mounted on top of the bypass chamber which is installed adjacent to an open or pressurized tank and connected to it by two pipes. Operating on the principle of communicating vessels, the bypass chamber reflects the same level as in the tank. Questtec can also supply an all-in-one solution consisting of a bypass chamber with any of the Endress & Hauser family of Radar Products.
