Installation Gammapilot M FMG60 FOUNDATION Fieldbus Installation Incoming acceptance, transport, storage 2.1.1 Incoming acceptance Check the packing and contents for any signs of damage. Check the shipment, make sure nothing is missing and that the scope of supply matches your order. - Page 9 Gammapilot M FMG60 FOUNDATION Fieldbus Installation 2.2.2 Installation conditions for level measurement Conditions • For level measurements the Gammapilot M is mounted vertically; if possible the detector head should point downwards. • In cascading mode no gap should occur between the measuring ranges of the different Gammapilot M.
- Page 10 • If only horizontal pipes are accessible, the path of the ray should also be arranged horizontally to reduce the influence of air bubbles and sediments.. • The Endress+Hauser clamping device (see BA00329F/00/EN, Chapter "Accessories") or an equivalent clamping device should be used for fastening the radiation source container and the Gammapilot M to the measuring tube.
- Page 11 Therefore, dia- gonal irradiation or the use of a measurement section is necessary for small pipe diameters. For the configuration of the measuring system please contact your Endress+Hauser sales orga- nization or use the "Applicator"...

Page 34: Calibration For Level Measurement And Limit Detection
Commissioning Gammapilot M FMG60 FOUNDATION Fieldbus Calibration for level measurement and limit detection 5.5.1 Basic principles The calibration points for the measurement are entered in the "calibration" (*1) function group. Each calibration point consists of a level and the associated pulse rate. - Page 35 Gammapilot M FMG60 FOUNDATION Fieldbus Commissioning Full calibration Refers to the following situation: • The radiation is switched on. • Within the measuring range, the vessel is filled as far as possible (ideally: 100 %, min. 60 %). If the vessel cannot be filled to at least 60 % during the calibration, the full calibration can alternatively performed with the radiation being switched off, which is a way of simulating a filling of 100 %.
- Page 36 Commissioning Gammapilot M FMG60 FOUNDATION Fieldbus Background calibration Refers to the following situation: • The radiation is switched off. • If possible, the radiation path is completely covered. The background calibration is necessary, in order to register the natural background radiation at the mounting position of the Gammapilot M.
- Page 37 Gammapilot M FMG60 FOUNDATION Fieldbus Commissioning Methods for entering the calibration points Automatic calibration For an automatic calibration, the vessel is filled to the required value. For the background calibration the radiation remains switched off, for the other calibration points the radiation is switched on.The Gammapilot M automatically records the pulse rate.
