Kobold’s new module level measurement duo - double safeguards process level control

KOBOLD Instrumentation, represented in South Africa by Instrotech – a Comtest Group company – has combined and modularly constructed their NGM (remote transmission level measurement) with the proven NBK (bypass level indicator) to produce a level instrument which works on the principle of Time Domain Reflectometry (TDR), or guided microwave/radar.

Radar level measurement using Kobold’s NGM provides a remote transmission of the level measured, whilst Kobold’s NBK provides a local optical level indication and an option of multiple magnetic level switches for high, low or intermediate level alarms. This ensures a dual safety in level monitoring. Even at larger distances, liquid levels in tanks and vessels are clearly visible thanks to the KOBOLD NBK bypass level indicators. The optical roller or ball display provides a permanent level visualisation of tanks, even in case of power failure. A redundant level measurement may also be provided with an optional reed chain and transmitter.

The combined duo instruments are suitable for water, fuel, various chemicals, and oil up to a viscosity of 460 mm²/s. Depending on the medium, the bypass tubes and radar probes may be delivered in stainless steel or different plastics. With a single device, levels up to 5500mm can be measured. In larger tanks, the measurement range can be extended by mulitpart versions with two or more sections. The protection rating of the electrical components is IP65 or better.
