3 Nivowave Continuous level measuring system Applications / Overview The Nivowave is a non intrusive acoustic wave measurement system. It is used for level monitoring of solids and liquids. It can be delivered with ATEX approval for use in Hazardous Locations. The Nivowave system is normally mounted at the top of the silo or tank. A selection of fields of applications and industries: Water / Waste water: Inlet screens, sumps, pump stations, water towers, dam level, chemical, open channel flow etc. Level measurement in solids Mining: Crushers, surge bins, ore passes, conveyor profile, blocked chute, stockpile, stackers, reclaimers, storage silos etc. Powers stations: Boiler bunkers, raw coal bunkers, ash pits, fly ash silos, etc. Food Plastics Chemicals Irrigation Cement Grain Paper Quarries Standard Series with horn for high performance in complex solid applications Integral NW 000 series Smart NW 000 series Remote NW 00 series (Transducer) With display and programming buttons implemented Without display and programming buttons.

4 Nivowave Overview / Function Level measurement in liquids Integral NW 000L series Continuous level measuring system Smart NW 000L series Light series without horn for normal liquid applications With display and programming buttons implemented Without display and programming buttons. Programmable with Nivowave PC- software Integral NW 000 series Smart NW 000 series Standard Series with horn for high performance in complex liquid applications With display and programming buttons implemented Without display and programming buttons. Programmable with Nivowave PC- software Function The Nivowave emits a high powered acoustic wave transmit pulse which is reflected from the surface of the material being measured. The reflected signal is processed using specially developed software to enhance the correct signal and reject false or spurious echoes. The transmission of these high powered waves ensures minimal losses through the enviroment where the sensor is located. Due to the high powered emitted pulse, any losses have a far less effect than traditional ultrasonic devices. More energy is transmitted hence more energy is returned. The receiver circuitry is designed to indentify and monitor low level return signals even when noise levels are quite high. The measured signal is temperature compensated to provide maximum accuracy to the outputs and display. Advantages Large selection of transducers. No contact between the tranducer and the material. Suitable for measuring many different applications. Easy to calibrate and commission. Wireless monitoring and programming with GSM possible. page G gi00 NW

16 Nivowave Mounting General Safety Instructions Continuous level measuring system Process pressure Chemical resistance against the medium Environment and installation conditions Industrial conditions Working temperature Mounting location Flange mounting Improper installation may result in loss of process pressure. Materials of construction are choosen based on their chemical compatibility (or inertness) for general purposes. For exposure to specific environments, check with chemical compatibility charts before installing. Do not put into service where there is a possibility of contact with acetic acid. Environment and installation conditions should be checked regularly This equipment is designed for use in normal industrial conditions relating to humidity, vibration, etc. If the user intends to operate the equipment in more severe environmental conditions, the manufacturer or local distributor should be consulted for advice. The working must not exceed the operating temperature range stated in the technical data. The right mounting place is significant for a proper function. Observe mounting instructions. A plastic sealing must be used to tighten the flange. Additional Safety Instructions for Hazardous Locations Installation regulations UV For devices to use in Hazardous Locations the respectively valid installation regulations must be observed. To prevent the effect of long term UV exposure, the transducers must be protected from direct sunlight. Amplifier mounting Mounting NW 00 and NW 000 Select a suitable mounting position that is not in direct sunlight. If necessary, utilize a sunshade. Observe the minimum and maximum temperature limits. Do not mount near sources of high E.M.F. such as high current cables, motor starters, or S.C.R. variable speed drives. Avoid mounting in high vibration areas. If necessary, use rubber absorption mounts if mounting in light vibration areas. page G gi00 NW

17 Nivowave Continuous level measuring system Mounting Transducer mounting Mounting position Selecting a suitable position to mount the transducer on the vessel is the most important step. Please read the following installation guide and contact your representative if you have any doubts or questions. A clear line of sight from the transducer to the product being monitored is preferred. First priority is to keep the transducer away from fill pipes, ladders, beams etc. Normal measurement of solids does NOT require aiming to the material angle of repose. Aiming the Transducer to the material angle of repose is only in seldom cases necessary. It is required, if any ladders, beams etc cause wrong echoes. In this case, use the Aiming kit to blank these wrong echoes. Solids Liquids Due to the high transmitted power of the transducer it is normally NOT necessary to aim the transducer to the material angle of repose. Enough echo is reflected by vertical mounting. Vertical mounting of transducer Vertical mounting of transducer Distance to vessel roof Standard series Light series Nozzle Horn The horn must protrude at least 0mm (") into the vessel. See in table on page G the dimension "B" of the horn. Use this value as a reference to define the max. height of the nozzle. The face (membran) of transducer must extend at least mm (0.") into the vessel. See dimension on page G. NW gi00 page G

18 Nivowave Mounting / Electrical installation Blanking distance Continuous level measuring system The transducer face must be at least the Blanking distance away from highest product level at all times. Increase the distance of the stated values by 0% if there is foam, dust, steam, or condensation in the vessel.

Installation regulations Fuse RCCB protection Power supply switch Wiring diagram Supply voltage Cable gland The local regulations must be observed. Use a fuse to protect the power supply circuit and the output circuits. In the case of a defect, the distribution voltage must automatically be cut off by a RCCB protection switch so as to protect the user of the device from indirect contact with dangerous electric tensions. A voltage-disconnecting switch must be provided near the device. The electrical connections are made in accordance with the wiring diagram. Compare the supply voltage applied with the specifications given on the name plate before switching the device on. Make sure that the screwed cable gland safely seals the cable and that it is tight (danger of water intrusion). Cable glands that are not used have to be locked with a closing element. page G gi00 NW

19 Nivowave Continuous level measuring system Electrical installation Field wiring cables All field wirings must have insulation suitable for at least 0V AC. The temperature rating must be at least 0 C ( F). Connecting the terminals Make sure that max. mm (0, ) of the pigtails are bared (danger of contact with live parts). Relay protection Provide protection for relay contacts as to protect the device against spikes with inductive loads. Additional Safety Instructions for Hazardous Locations Installation regulations Cable glands Cables Earthing For devices to use in Hazardous Locations the respectively valid installation regulations must be observed. The used entry devices and blanking elements must have an adequate type approval and a temperature range of at least 0 C (- F) to +0 C ( F). In addition they shall be suitable for the conditions and correctly installed. Where applicable the provided original parts of the manufacturer must be used. To be compliant, the equipment must be installed with suitable protection for the cable. It must be protected in a suitable manner and terminated in an enclosure suitable for the environment. A pull relief must be provided for the cables, when the device is installed with the factory provided cable glands. Cables must only be replaced by the same cable type. If extending the cable, it must be protected in a junction box and terminated in an enclosure suitable for the environment. Where earth connection is present, the units must be earthed.

23 Nivowave Continuous level measuring system Electrical installation NW 00, NW 000, NW 000L, NW 000, NW 000L series Avoid of Cross Talking of multiple Transducers Cross Talking situation When installing more than one Transducer in a silo, it can happen, that one Transducer influences the other, which can lead to a wrong measurement. To avoid this, following wiring and programming is recommended: Wiring To reach a common ground for all Nivowaves, it is necessary either to connect all DC-IN - or all Earth terminals in parallel. Note: DC-IN - and Earth are connected together inside the Nivowave. To next Nivowave Programming In the software setup of each Nivowave (Output Adjust Menu), program Relay to FS (Failsafe) mode. You could use a different Relay number in the same way, if Relay is needed for another function. Function TEST IN connection: While the Transducer is pulsing, the TEST IN connection is driven to 0V by this Nivowave. While the TEST IN is set to 0V from outside (by another Nivowave), the Transducer will not pulse. The combination of these two functions avoid, that the Transducers can pulse at the same time. This means that no crosstalking can happen. To reach this, it is necessary to connect the TEST IN terminals of the Nivowaves together. Relay: The Relay (programmed into Failsafe mode) is in line with the TEST IN connection. The function of this is to prevent a possible lock up of the whole system if one Nivowave has a problem (such as power failure). Any time that a Nivowave is in the failed state, it will be disconnected by the Relay from the other Nivowaves, so they can continue working together. NW gi00 page G

27 Nivowave Continuous level measuring system Electrical installation Modbus: Accessories for a Modbus Network Use of Biasing network PK PK is used to stabilize the Modbus network, if long cables are used. It implements also the needed Terminal resistor at the beginning of the network. Required voltage: DC+/DC- V DC The Biasing network with Terminal resistor can be part of a Modbus Master, or be a separate module. The design or the values of the components can be different, when using other suppliers of a biasing network. It must be able to ensure a proper working voltage of ca. 00mV between A and B, if none of the connected Modbus units is talking.
