Level measurement guided radar

General Information

Guided radar level measurement

Guidense TDR100

Precise continuous level measurement and reliable point level detection combined in one device. The Guidense continuous guided wave radar (GWR) uses Time Domain Reflectometry technology: impulses, generated by the sensors circuitry, are propagated along the probe which is immerged in the liquid or solid to be measured. The sensor can transmit the analysed level as a continuous analog output signal or as a control output signals. The Guidense TDR100 can be used with any of the F- and D-Series level monitors and controllers.
Within the Guidense family a Smart sensor is also available! Together with the M844 Data Acquisition and Communication Module from ProcessMonitor you can easily read, modify, store and analyze all process parameters from anyplace, anywhere, anytime using a web browser.

Best price-performance ratio in the market!

The Guidense is your first and best choice when it comes to reliable level measurement. The Guidense guided wave radar is the multi-applicable alternative for traditional measurement principles like ultrasonic, capacitive, conductive and pressure level measurements. The Guidense is not affected by changing process variables, such as density, conductivity, viscosity, temperature, pressure, vapor and dielectric constant. We offer the Guidense for an attractive price. Combined with the user-friendly features below, for sure the best price-performance ratio in the market!

Very easy to install More >>

Mechanical installation has almost no restrictions and can be done easily. Due to its relatively small G3/4" process connection thread, the Guidense can be mounted at nearly any existing tank nozzle by screwing it directly into a standard threaded tank connection. Configuration of the TDR100 isn't any harder. Easy configuration can be done by your own crew instead of expensive service engineers. The TDR200-SMART is a plug-and-play solution with the Processmonitor M844 Data Acquisition and Communication Module.

Key applications More >>

Application example

The Guidense TDR200-SMART is an extremely suitable Smart level measurement solution for off-grid and hard to reach locations.

Suitable in almost every liquid and solids - independent of changing process conditions, such as density, conductivity, temperature, pressure, vapor and turbulence.

All types of process and storage tank applications and has an exceptional performance in media with low dielectric constant (i.e. low reflectivity) such as oils and hydrocarbons.

The Guidense has almost no installation restrictions - it can be mounted in small tanks, tall and narrow nozzles and it measures precisely even with difficult tank geometries or close to interfering structures.

For hazardous area applications, the Guidense TDR100, certified according ATEX II 1/2 G Ex ia/d IIC T6 Ga/Gb, is available on request.

Probe types More >>

To meet various application requirements, the Guidense has three different probe types: single rod probe, wire rope probe and coaxial probe.

  • The single rod probe is recommended for installations in liquids and in bypass chambers and stilling wells.
  • The wire rope probe is recommended for installations in solids, tall tanks and where limited headroom is available.
  • The coaxial probe is the ideal solution for a hassle-free application; ensuring reliable measurement under almost all conditions.

An extended temperature option for the single rod and coaxial probe is available on request. A temperature extension is added between the housing and the feedthrough, which reduces the application temperatures (-200°C to +250°C) inside the tank to standard levels that will not damage the sensor electronics inside the housing.

For chemically aggressive and corrosive environments in which the standard stainless steel probe material is not durable enough a single rod probe with PTFE coating is available on request.
