The instrument is ideal for all applications in water level measurement in open channels, rivers and lakes. It is suitable also for the measurement of wave parameters on the sea. 4.2 Principle of operation The LPR level probing radar is based on radar technology. This technology is independent from temperature and humidity changes, providing accurate measurements in all weather conditions. In the FMCW (Frequency Modulated Continuous Wave) radar the electromagnetic signal is continuously transmitted. The frequency of this signal changes over time, in a sweep across a set bandwidth. The difference in frequency between the transmitted and received

(reflected) signal is determined by mixing the two signals, producing a new signal which can be measured to determine distance. A saw-tooth function is used to change the frequency pattern for the emitted signal that is swept linearly in frequency. The received signal is then mixed with the emitted signal and due to the delay caused by the time of flight for the reflected signal, there will be a frequency difference that can be detected as a signal in the low frequency range. The low frequency (IF) signal has to be processed by FFT and other mathematical functions to calculate the effective range. 14 CAE S.p.A. 4 N O I T P I R C S E D T C U D O R P 4.3 Advantages High resolution distance measurement Mm-wave FMCW radars can have very high resolution for ranging, velocity and imaging application. Quick updating of measurement Because FMCW mm-wave radars are continuously transmitting a signal, there is a very short delay in measurement updates. Functions correctly in many types of weather and atmospheric conditions Due to the short wavelength of the electromagnetic radiation used, mm-wave systems have excellent performance in rain, humidity, fog and dusty conditions. The short wave-length means that raindrops, water vapor or dust particles do not block wave propagation easily. Heavy rain is generally required before a reduction in range or resolution occurs. mm-wave systems will function identically during day or night. FMCW radars are also immune to effects from temperature differences, or high temperatures. The actual water level of the waterway is then calculated automatically, if required, by the radar sensor. To do this, on initial startup there is the possibility of inputting the relevant measurement mode and a reference value. Two standardized electrical interfaces are available for connecting the LPR to a datalogger or peripheral devices: RS-485 (SDl-12 protocol) and 4-20 mA. When using the 4-20 mA interface, it is possible to scale the measurement output to a smaller measuring range.

Installation 5.1 Assembly instruction ............................... 18 5.2 Mounting ................................................. 19 5.3 Criteria for selecting a suitable mounting location .................................................... 20 The electrical installation of LPR may only be carried out by qualified personnel. CAE S.p.A. 17 5 N O I T A L L A T S N I 5.1 Assembly instruction The electrical installation of LPR may only be carried out by qualified personnel. The LPR mounting bracket must be fixed to the sensor by mean of three M8 hex bolts and washers. Its advisable to mount first the bracket on the support tube and then the sensor on the bracket. The bracket is designed to be mounted on a support tube with a 1 1/4 Gas male threaded terminal. 18 CAE S.p.A. 5 N O I T A L L A T S N I 5.2 Mounting The sensor support tube must be easily removed or turned to ensure access to the sensor but at the same time it must ensure a stable and vibration-free mounting. Mount the bracket on the threaded support tube. To ensure a good mechanical attachment and an easy disassembly it is appropriate to use teflon tape on the male thread. The alignment of the sensor parallel to the water surface must be carried out as accurately as possible!

deviation from the parallel alignment leads to a linearity error. incorrect alignment of > 4 can lead to a function failure of the CAE LPR

(depending on the other operating parameters such as distance between lower sensor edge and water surface). The connection cable can be routed inside the support tube and must be wired on the supplied 7 pole socket connector. CAE S.p.A. 19 5 N O I T A L L A T S N I 5.3 Criteria for selecting a suitable mounting location Possible mounting locations are, for example, bridges and auxiliary constructions directly above the waterway section to be measured. The minimum distance between the lower edge of the sensor and water surface must be 0.5 m 1.64 ft (dead area in which no useable measurement is possible). Select a mounting point high enough so that the measurement is possible even with high water levels. The mounting point must be steady. Vibrations and movement of the mounting point must be avoided. Bridges are affected by movements of several centimeters as a result of load changes and temperature movements. lf pillars are available, the sensor can be mounted to a stable positioned pillar with a suitable spacer. The water surface must be as smooth as possible in the area of the sensor beam. Avoid turbulent areas, areas where foam is created, surge areas and waterway sections where obstructions or bridge piers cause changes in the water level. The measurement result cannot be used if there is ice or snow on the water surface!

Choose a mounting location that does not become dry at low water levels. Stations subject to very rapid changes in water level are not suitable. The LPR averages its measurement result over a measuring time from 6 to 50 seconds. The area within the sensor beam (see Figure below) must be completely free of obstructions. Sensor beam 20 CAE S.p.A. 5 N O I T A L L A T S N I Table for approximating the size of the sensor beam Target Distance Sensor beam diameter 2 m 5 m 10 m 15 m 20 m 25 m 30 m 35 m 6.56 ft 16.40 ft 32.81 ft 49.21 ft 65.62 ft 82.02 ft 98.43 ft 114.83 ft 0.42 m 1.06 m 2.12 m 3.19 m 4.25 m 5.31 m 6.38 m 7.44 m 1.39 ft 3.49 ft 6.97 ft 10.46 ft 13.95 ft 17.43 ft 20.92 ft 24.41 ft The diameters given are minimum sizes. Where possible, select an area free of obstruction that is clearly larger. Avoid large metal surfaces near the sensor beam (reflections from these surfaces can distort the measurement result). The climate specifications in the technical data must be kept at the mounting location. To be in compliance with the European normative it is necessary to observe the installation clauses reported in Par 2.4 EC Conformity. Danger of explosion due to spark formation and electrostatic discharge The use of the CAE LPR in explosive atmospheres can lead to the danger of ignition of this atmosphere. An explosion resulting from this involves the risk of very severe material and personal damage. Never operate the CAE LPR in explosive areas (e. g. in sewers). The CAE LPR is not equipped with EX-protection (EXplosion protection)!. CAE S.p.A. 21 5 N O I T A L L A T S N I Page intentionally left blank 22 CAE S.p.A. 6 G N I R I W 6.

GND RS485-A RS485-B Power 4-20 mA Out+ 4-20 mA PGND GND The sensor is supplied with a 7 pole cable socket connector, mating with the plug of the sensor. The connectors, when tightened, are IP67 rated. The socket connector may be cabled to connect the LPR to the datalogger or acquisition device. The cable screen must be connected only on the datalogger side. For the cabling refer to the datalogger instructions. 6.2 Connecting power supply The LPR sensor requires a power supply of 11-16 V DC, typ. 12/14V DC (i.e. using batteries or mains connection with galvanically separated low safety voltage). Secure the power supply positive terminal cable (terminal 1 of the supplied connector) with a fuse (1 ampere, reaction time: fast) and wire power supply Gnd to pin 2 of the connector. When using solar panels, its recommend to use an overvoltage protection device. 6.3 Connecting LPR using RS485 interface Connect the CAE LPR to a RS485 SDl-12 input of the datalogger. Follow the datalogger handbook for this operation. Refer to Par. 7 for the LPR connection assignments. The maximum length of the connecting cable is 100 m - 330 ft. Recommended wire cross-

section: 0.5 mm2 - AWG 21, 4 wire cable, external diameter 6-8 mm. Using this cable due to cable resistance the minimum Power is 12V. The SDl-12 commands for the LPR are shown in Chapter 9, SDl-12 protocol. 24 CAE S.p.A. 6.4 Connecting LPR using 4-20 mA interface Connect the CAE LPR to a 4-20 mA input of the datalogger. Follow the datalogger handbook to carry out this operation. Refer to Par. 7 for the CAE LPR connection assignments. The maximum connecting cable length/recommended wire cross-section depends on the amount of voltage supply and the burden amount (load resistor). Please note that the ohmic resistance of the connecting cable, together with the eventually existing burden, does not exceed the maximum allowed load resistance!

6 G N I R I W The 4-20 mA interface of the CAE LPR is passive. lf needed the supply for the current loop must be injected by wire-linking the supply voltage. Tip: To connect the CAE LPR using the 4-20 mA interface, a minimum 4-wire cable is required, it is possible to connect together pin 1 and 5 of the connector and the power supply maximum voltage is 16V, the Gnd supply must be connected to pin 2. The 4-20 mA output (positive) must be connected to pin 6. The 4-20 mA return GND (second pole of the burden resistor) must be connected to the PGND terminal. lf the LPR must also be configurable via SDl-12 commands, use a 7-wire (cable length up to 100 m). The load resistance (burden+ohmic resistance of the connection cable) connected to the CAE LPR must not exceed a specific maximum value. This value depends on the supply voltage level at 4-20 mA loop. lf the load resistance is greater, the output current can no longer be evaluated. Smaller load resistances are allowed. Read off the maximum load resistance for your power supply from the following diagram. CAE S.p.A. 25 6 G N I R I W Maximum load resistance Example: Power supply 12 volt max. load resistance 450 ohm. The LPR delivers an output current corresponding to the measured value for a load resistance up to 450 ohm. Dimension the connected electrical circuit accordingly. Check the input resistance of the connected peripheral device for this purpose. The 4-20 mA scale value is scaled according the maximum and minimum distance programmed. The default values (0-35m) can be programmed by SDI-12 extended command for minimum and maximum value (see Par 9.4). It is also possible to assign the 4-20 mA output at any of the measure parameters. By default the 4-20 mA output is disabled. 26 CAE S.p.A. 7 N O I T A R U G I F N O C 7. Configuration 7.1 LPR Software Config ................................ 28 CAE S.p.A. 27 7 N O I T A R U G I F N O C 7.1 LPR Software Config The LPR Software Config software utility is available for the LPR configuration and testing. This tool is available for Microsoft Windows versions 7, 8 and 10 and it is connected with the sensor by RS485 / Sdi-12 interface. CAE has tested the FTDI USB-RS485-WE-1800-BT and FTDI USB-RS485-WE-5000-BT cables that are suitable for this use. For more details see LPR Software Config User Manual available in www.cae.it. 7.2 Operational modes The LPR can be operated in several different modes. There are two main functional modes:

Hydrometer: the sensor measures the water level (by command or time scheduled) Wavemeter: the sensor measures the water level continuously, processing the elementary measurement to obtain the wave parameters Each of the two functional modes has two operational modes:

Continuous Mode: the sensor takes the measurement by scheduled time Polled Mode: the sensor takes the measurement using SDI-12 protocol command The functional and operational modes are programmable by SDI-12 commands. The measure output can be placed on the 4-20 mA interface (only 1 parameter) and can be configured to scaled on a specific range of distance by mean of specific SDI-12 configuration command. Also the Continuous interval is used to update the 4-20mA value measure. 7.3 Operational parameters In Hydrometer modes the main parameters to set are:

Hydrometric offset, to align the LPR readings to the hydrometric level. Minimum distance Maximum distance Number of the elementary measures It is also possible to set a dead band where obstacles may not be detected. It is advisable to set the minimum and maximum distance to the effective minimum and maximum distance possible (i.e. the distance at minimum water level and the distance at maximum water level). The 4-20 mA output is automatically fixed by the minimum-

maximum distance range. The distance to set is from the sensor to the water and not the offset corrected value (hydrometric level). 28 CAE S.p.A. 8 G N I T O O H S E L B U O R T 8.
