    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 sidewalls or sometimes even in the presence of dusting.

    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-hole diameter of 125 mm (5″) for fixing it. For easy installation, it is recommended to use NIVELCO's special flange with a split insertion, available with four sizes of DN125/150/200/300 (to be ordered separately).
  • Page 12 Mounting EchoTREK versions SD–33– and SD–34–: Check that the split flange matches the holes of the counter-flange on the silo. Remove the split insert from the flange and put the flange around the aiming arm between the sensor and the aluminum base. Slide the split insert back to its place and screw the ball joint housing to the flange with the four M12 bolts to such an extent that the aiming arm can move freely through and tilt by the ball joint for the aiming process.

    5.3.2. Current output scaling This is a fast and straightforward way to modify the scaling of the current output. For changing all parameters other than those assigned to 4 and 20 mA, use the QUICKSET (5.3.2) or the Full Parameter Access (5.3.3). Measuring continues during programming using the old parameter set. The new parameter set will be valid after returning to measurement from programming mode.

  • Page 27 P03: - - - a Displayed Values – Rounding (DIST) display ISTANCE It is crucial to remember that the instrument is measuring distance as the base quantity, and all the other process values are calculated from this base quantity. The resolution of the measured distance is 1 cm, which is reflected in the calculated (level, volume) values. But the displayed value of the calculated volume (VOL) can be rounded.

  • Page 29 P05: - - - - Minimum measuring distance (Dead zone - Close-end blocking) One of the basic characteristics of ultrasonic level measurement is the denial of any echo within the close-end blocking range, also called the dead zone. This range is the minimum measuring distance, which the level transmitter can measure. By increasing this parameter, disturbing objects and false reflections close to the sensor can be eliminated.
  • Page 30 P06: - - - - Far-end blocking Far end blocking is used to neglect incorrect level/volume readings and output actions below a pre-set level. For example, tanks with heaters or other interfering objects (sludge, cone of the silo, etc.) may cause faulty readings at the far end of the measuring range.

  • Page 31: Analog Output

    5.4.2. Analog Output P10: - - - - Value (of distance, level or volume) assigned to 4 mA current output P11: - - - - Value (of distance, level or volume) assigned to 20 mA current output Values are interpreted according to P01(a). The process and current loop output values can be assigned to each other either directly or inversely. For example, if the 1 m (3.3 ft) level is assigned to 4 mA and 10 m (32.8 ft) is assigned to 20 mA, it represents a directly proportional relation, while assigning 1 m (3.3 ft) to 20 mA and 10 m (32.8 ft) to 4 mA represents an inversely proportional relation.
