Pic. 8.4 Determining of measuring probe’s length
Next:
1) Cut the meted part of the probe’s tube. The cut must be made carefully, burrs must be
removed. The plane of the cut should be perpendicular to the guide line of the pipe. We
recommend using a special tool for cutting pipes. Type of the instrument is listed in Table 5.
2) Install an insulating cap ES.217 at the end of the probe, as shown on Picture 8.5, on the left:

3) Fix the central conductor of the probe. To do this, you should pull up to the stop (the length
of free movement of compressing spring 5 mm), fold and put the central conductor to the
grooves of stub, as shown on Pictures 8.5 and 8.6.

4) Check the quality of the tension. To do this, you should gently tap with your finger on the
probe (probe should be screwed to the measuring head against the stop) – you should feel the
vibration of the string taut (central conductor).
Cut the remained part of the conductor in the way that the cut was roughly in the center of a
stub.
5) Apply a drop of sealant (type shown in Table 5) on the place of conductor’s cut for providing
protection of the end of the conductor from water that may accumulate in the tank.
