    Nuisance Process Trips due to Nucleonic Detector (Density Gauge Level Measurement System)

    Thanks for your advise. I am only onshore support and will recommend offshore to do utilize scope, etc. I am based in UK north sea sector.

    Nuisance Process Trips due to Nucleonic Detector (Density Gauge Level Measurement System)

    We do have water injection pumps which is injecting water in the reservoir to improve the production. The actual motor speed is variable and is getting controlled via some control panel which I am not familiar with. I will look into this in more detail exactly what we got and get back with some...

    Nuisance Process Trips due to Nucleonic Detector (Density Gauge Level Measurement System)

    Right... Test conducted for RF interference. Nothing happened which I was expecting. So it must be something else..

    Radiation interference concern for transmitters

    If it's a nucleonic detector (e.g. tracerco, vega, etc) then you will notice the detector going over-range (i.e. in fault due to going out of range) during radiography. The way nucleonic detectors work is there is a source (CS-137) on one side of vessel and the receiver (scintillation crystal...

    Nuisance Process Trips due to Nucleonic Detector (Density Gauge Level Measurement System)

    Thanks all for response. We are having this issue on number of vessels. So the source (CS-137) is only one and there are two separate nucleonic detectors (receivers) mounted on other side of vessel next to each other. One is used for DCS (alarms) and the other is used for ESD (trip - safety...

    Suggestions for H/L/LL level switches in a large tank?

    If you have exhausted all options (e.g. GWR as that will be my preference, etc), my suggestion would be: For point measurement, you could install 2 off mobrey float switches (one for Hi Alarm and one for Lo Alarm) if you have two off nozzles at the side of the tank. For continuous...

    Nuisance Process Trips due to Nucleonic Detector (Density Gauge Level Measurement System)

    Hi georgeverghese, The source is side mounted and the receiver is mounted on the other side of the vessel and both are non-intrusive. The source CS-137 is continuously emitting radiation which are being picked up by the receiver on the other side of vessel. The no. of counts received at...

    Nuisance Process Trips due to Nucleonic Detector (Density Gauge Level Measurement System)

    We have a nucleonic density gauge level measurement system on a vessel which is measuring the bulk oil level in the vessel. The source (emitter) is Cesium CS-137 and the detector is scintillation type detector both (source and detector) mounted external to the vessel i.e. non-intrusive. The...
