INSTALLATIONPLACEMENTTo find the ideal position for the location of the EchoTREK level transmitter variousconsiderations should be made.The transmitter should not be installed in the centre of the tank/silo when the tank roof is domeshaped or conical. The ideal position for the EchoTREK is on the r = (0.3 … 0.5) R (in case ofcylindrical tank). Avoid that the 5° conical beam angle of the transmitter contact the tank/silowall. This case the transmitter is mounted too close to the wall, therefore it should be tilted (Seesection “Aiming”).To avoid overheating the instrument should be protected against direct sunshine.rRSunshadeGRAVITY FILLINGThe device should bemounted as far as possiblefrom the filling stream.PNEUMATIC FILLINGSelect a location where the speed of thein-flowing material is the smallest.Ex type units are not allowed to beinstalled in the dust path of thepneumatic filling!Suggested location (view from above)40 m 3,8 m50 m 4,7 mMOUNTING (see illustration of mounting options on the next page)The EchoTREK consists of a sensor that is attached to the aiming arm (a pipe with a ball-joint housing incorporating a ball joint) that is attached to the housingof the electronics. It is recommended to mount the transmitter on the roof of the tank/silo using a flange (See drawing). The Ball-joint housing has a screw-holediameter of 125 mm for fixing it. For easy installation we recommend to use our special flange with a split insertion, available with four sizes ofDN125/150/200/300 (to be ordered separately). Removing the split insertion, the flange is to be put around the aiming arm and the ball-joint housing is to befixed to the split flange. It is essential to use the washers and the bolts (4 pcs each) delivered with the split flange. The ball-joint will be pressed to the housingby a spring allowing adjustment/aiming. The 4 pcs of M12 bolts have to only be tightened after completing the adjustment/aiming. The maximum torque fortightening the bolts is 3.5 Nm.
