Page 5: Introduction
A 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. -
Page 6: Techical Data
The following types of applications are possible depending on the communication and what the output signal is used for: 1. 1.Using the unit as a three - or four -wire current transmitter. Normally, we use the analogue (4…20 mA) output signal of the EasyTREK. The application parameters of the device are set through HART communication at installation (right after installation or in a laboratory, prior to installation). -

Page 10: Installation
INSTALLATION LACEMENT To find the ideal position for the location of the EasyTREK level transmitter various considerations should be made. The transmitter should not be installed in the center of the tank/silo when the tank roof is dome shaped or conical. The ideal position for the EasyTREK is on the r = (0.3…0.5) R (in case of cylindrical tank). -

Page 13: Putting Into Operation, Adjusting, Programming
PUTTING INTO OPERATION, ADJUSTING, PROGRAMMING 5.1. Putting into operation After switching on the correctly wired unit the transducer begins to click audibly. In about 20…50 s the ECHO LED goes on and a signal between 4…20 mA appears on the current output. When first powering the unit, it measures with the standard manufacturer’s settings (see some of the most important parameters below). -

With the aid of EView configuration software run on PC By the NIVELCO made MultiCONT multichannel controller This instruction describes parameters and features behind them but does not deal with technical details for their selection and editing of their values. Compact Disk attached to the transmitter contains detailed information on the Eview configuration software (to install on PC) and its description. -

- Page 18 P05: - - - - Minimum measuring distance (Close-end blocking) FACTORY DEFAULT: automatic close end blocking (Xm as per the table) Basic feature of the ultrasound level meters is they’re not being able to measure next to the sensor surface. Within this range the measurement cannot be interpreted, thus it should be avoided that material level get into this range.
- Page 19 P06: - - - - Far-end blocking FACTORY DEFAULT: 0 Far-end blocking is the range below the level set in parameter P06. Far-end blocking can be used to avoid disturbing effects of stirrers or heaters at the bottom of the tanks. When the unit detects echoes in this range it gives special signals.

Tracking speed Remark Standard For most applications Fast For fast changing level For very special cases only, as this reduces the maximum measuring range to 50% of the nominal value! The Special measuring window (P25 and P33) is inactive and the EasyTREK will respond practically instantly to any target.
