Page 6: Introduction
INTRODUCTION The series LU level transmitters are electronic equipment based on the transmission of ultrasonic waves to measure the distance to a liquid or solid in a vessel. The microprocessed electronic circuit offers the following features: Emission and reception circuits for the ultrasonic signals, and microprocessor treatment. -
Page 7: Storage Temperature
Storage temperatures Sensors of : PVDF -20ºC ..+60ºC -5ºC ..+50ºC INSTALLATION To make the instrument work in the best conditions, it is important that the bottom face of the sensor is installed parallel to the surface of the product to be measured. In the case of liquids, the face of the transducer should be horizontal. -
Page 8: Obstacles In The Vessel
Model Dead zone Max. distance (liquids) Max. distance (solids) LU912 0.3 m 2.5 m LU932 0.45 m 10 m In cases where it is necessary to measure distances shorter than the dead zone, a reflector can be installed as shown in the figure. The measured distance will be the addition of the real distance plus the distance between the transducer and the reflector. -
Page 9: Filling Entries
Filling entries It is not recommended to install the level transmitter in the upper zone of a filling entry, because the instrument could detect the level of the jet filling instead of the level of the stored product. Foams Some liquids generate foams when in movement. In vessels with agitators, or in the filling processes, important layers can be generated that weaken the reflected signal which is essential for measuring the level. -
Page 10: Electrical Connection
ELECTRICAL CONNECTION For the electrical connection, the LU level transmitter is provided of terminal strips. To help in the wiring of the equipment, the description of the terminals is marked next to each terminal strip. For the electrical installation it is recommended to use multiple conductor cables with individual cable sections in the order of 0.25 to 0.5 mm in order to make it easier to connect. -
Page 11: Alarm Outputs Wiring
NOTE: The analog output has protection against reversed polarity. Due to another protection against overvoltages, if a loop supply voltage with inverted polarity and higher than 32 V is connected, the equipment may be damaged. Alarm outputs wiring Terminal Source output 1 Drain output 1 Source output 2 Drain output 2... -
Page 12: Operation
OPERATION Without display module The instrument allows programming the current loop limits by means of the 4 mA and 20 mA keys. To do this, the top cover must be remove, previously releasing the DIN913 M3 x 8 safety screw. The procedure is the following: Point the equipment to a flat surface and place it at the distance corresponding to 4 mA. -

INSTALLATION PARAMETERS Power on the electronic converter with the voltage indicated on the label. Press the (Enter) key in order to enter the main menu. With the keys (Down / Left) and (Up), select “Installation”, and then validate with the key (Enter). -
Page 17: Bottom Distance
8.1.1 Bottom distance The bottom distance is the distance between the transducer face and the bottom of the vessel. It allows to calculate el level with respect to that point. This parameter is necessary to visualize data in level mode or percentage mode, because the instrument takes this distance as a reference (see point 9.5 on page 26). -
Page 18: Dead Zone
The percentage of filling is calculated given the bottom distance and the top distance (see points 8.1.1 and 8.1.2 on page 17) , according to the following equation: di: bottom distance ds: top distance When the distance between the product and the sensor is “di”, the visualized percentage is Distance Bottom Distance... -
Page 19: Dead Zone Length
When programming this value, the no echo alarm is automatically programmed with the opposite value. 8.2.2 Dead zone length In some installations it may be convenient to increase the dead zone value. For example, in cases of vertical tube measurement. In this screen the dead zone distance in m can be programmed. -
Page 20: Operating Mode
In all cases the echo intensity is displayed by means of a value between 0 and 100. This intensity depends on the distance to the target, the type of product where the wave is reflected and the conditions of installation. If the distance of the product at the time of verification is longer than half the maximum measuring distance, it is normal that the intensity has a low value. -
Page 21: Measuring Units
Measurement units The instrument can indicate the measured distance or level in meters or feet. Decimals In this screen the desired number of decimals for the measured value is chosen. For the selection of the number of decimals it must be taken into account that an indication with an excess of decimals may give the sensation of instability of the reading. -
Page 22: Filter Time
9.3.1 Filter time By selecting a filter with a shorter or longer integration time, response to level variation will be obtained in more or less time. The filter time is selected in seconds, with a minimum value of 1 and a maximum value of 25 seconds. -
Page 23: Outputs
For example, if the time is set to 5 seconds, an object that interferes the ultrasonic wave path must remain 5 seconds so that the level transmitter takes this object into account. Outputs In this screen, one of the three outputs to be programmed can be selected: Analog (4-20 mA), Alarm 1 and Alarm 2 9.4.1 Analog output... -
Page 24: Current Calibration For 4 And 20 Ma
9.4.1.2 Current calibration for 4 and 20 mA The LU9X2 is delivered with the current output already calibrated. If you want to correct a derive of the 4 or 20 mA current values because they do not coincide with the ammeter used, it can be done by entering the ammeter value and pressing the key (Enter). - Page 25 Example 1 Suppose we work in level mode. If the output is programmed to activate at 1 m and to deactivate at 0.9 m, when the level is zero the output will be deactivated. When the level reaches a value of 1 m the output will be activated and it will not return to deactivated state until the level falls below 0.9 m.
