Fluidwell TDR100 Continuous Guided Level Radar | High Precision

The Fluidwell TDR100 Continuous Guided Level Radar is a state-of-the-art level transmitter designed for high-precision measurement of liquids and solids. Utilizing Time Domain Reflectometry (TDR) technology, this sensor provides accurate readings regardless of changing physical properties like density, conductivity, or temperature.

Description

The Fluidwell TDR100 Continuous Guided Level Radar represents a significant leap in level measurement reliability. Unlike ultrasonic sensors that can be diverted by foam or atmospheric changes, the TDR100 uses Guided Wave Radar (GWR) to send microwave pulses along a probe directly into the medium. This method ensures that the signal is concentrated and returns with high integrity, providing a measurement accuracy of up to ±3mm.

One of the primary competitive advantages of the TDR100 is its versatility across different media. It is equally effective in measuring liquids with low dielectric constants and solid powders or granules. Because the measurement is based on the time of flight of the pulse along a physical guide, it is completely unaffected by vacuum, high pressure, or turbulent surfaces. This makes it a superior alternative to traditional pressure or ultrasonic transmitters in complex industrial reactors.

Installation and setup are streamlined through an intuitive interface. The sensor can be configured to ignore internal tank obstructions like agitators or spray balls, preventing false readings. Its robust construction ensures a long service life with minimal calibration required, reducing the total cost of ownership for plant operators.
