- Page 3 EchoTREK! A Total beam angle of 5° at –3 dB is a feature of all Nivelco’s ultrasonic sensors designed for the level measurement of free flowing solids. This uniquely narrow beam angle ensures reliable measurement in narrow silos with uneven side walls or sometimes even in the presence of dusting.

3. INSTALLATION OSITIONING Sunshade Selecting optimal location for the transmitter various considerations should be made. If the measured material is granule (material size > 5 mm) and the tank roof is dome shaped or conical, do not install the transmitter in the centre of the tank/silo. In general the transmitter can be installed on the radius r= (0,3 …... - Page 8 Mounting EchoTREK versions S -33J and S -34J 1. Check the split flange for matching the bore-holes with that of the counter-flange on the silo 2. Remove the split insertion from the flange and put the flange around the aiming arm between the sensor and the Alu-base. 3.

Aiming should also be tested with full silo, since due to the great angle of repose the echo might be weak despite of the fact that level is near to the sensor. In such cases a reasonable compromise of aiming should be achieved that provide acceptable echo in every state of the filling. -

5. PROGRAMMING Modification of the parameters (programming) is required to customise the transmitter to the actual parameters of the tank/silo. Programming of the EchoTREK is described in the Installation and Programming Manual (3d edition)! Programming can be performed by the plug-in programming and indicator module SAP-100 (See chapter 5.2 and 6 of a.m. manual). EchoTREK of the series SB - is containing this module. -
