NGMThe modularly constructed NGM of KOBOLD works on the principle of Time Domain Reflectometry (TDR, also known as guided Microwave or guided Radar) and offers an excellent alternative to conventional level measurements. The NGM enables precise and reliable continuous level measurement and point level detection in almost all liquids. This innovative device 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.
