11.For your safetyAll operations described in this operating instructions manual must be carried out ouly by trainedspecialist personnel authorised by the plant operator.During work on and with the device the required personal protective equipment must always be worn. Operational reliability is ensured only if the instrument is properly used according to the specifications in the operating instructions manual as well as possible supplementary instructions. This device complied with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)this device may not cause harmful interference, and(2)this device must accept any interference received, including interference that may cause undesired operation.Changes or modifications not expressly approved by the manufacturer could void the user's authority to operate the equipment.Authorised personalAppropriate useFCC CertificationWarning: User must keep a safety distance of at least 20cm from the antenna. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: -- Reorient or relocate the receiving antenna. -- Increase the separation between the equipment and receiver. -- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -- Consult the dealer or an experienced radio/TV technician for help.
2.Measurement PrincipleThe extremely narrow microwave pulse emitted by the antenna on radar level instrument can travel at the speed of light and part of its energy, which is reflected off the surface of target medium, is received by the very same antenna. The time lapse between pulse emission and reception by the antenna is proportional to the distance between the surface of target medium and the reference point on antenna. However, due to the fact that the electromagnetic wave is transmitted at extremely high speed, which leads to the tiny time lapse (nanosecondlevel) and makes it difficult to be identified, GDRD series of radar level instrument have adopted a special demodulation technology, enabling itself to detect the time lapse betweenpulse emission and reception correctly, and eventually generate accurate measurement result.PrincipleThe pulse radar level instrument, adopted K band range as transmission frequency, which make this series have specialties as below: Small beam angle, which centralize energy, makeGDRD high ability of anti-jamming, hence high accuracy and reliable. Small antenna size,easy to mount and easy to equip extra dust protection. Small blind zone, good accuracyev en fo r s ma ll ve ss e ls .

4.Mounting RequirementsBasic Requirements7>200mm11211111111222233333 100% 0%4There is a certain existing beam angle while the antenna transmitting microwave pulses. There should be no barriersbetween the lower edge of antenna and surface of measured medium. Therefore it is highly recommended to avoidfacilities inside vessels, such asladders, limit switches, heating spirals, struts and etc, during the mounting process.“False echo learning” must be carried out during the installation in this case. Furthermore, microwave beams mustNOT intersect the filling streams. Be cautions during the installation: the highest level of target medium must NOT enter into blanking zone; the instrument must keep certain distance to vessel walls; every possible measure needs to be taken to position the instrument so that the direction of antenna emission is perpendicular to the surface of measured medium. The installation of instruments in explosion proof area must abide by relevant local or federal safety regulations. Stainless steel housing should be used for intrinsically safe explosion proof version, which is also applicable in explosion proof areas. The instrument must be connected with ground in this case.Illustrations1.Reference Plane2.Center of Vessel or Symmetrical Axis Minium distance of 500mm between instrument and vesselwall during installation The reference plane is the thread or flange surface1.

AReflection board installationIf there are barriers in vessels， it isrequired to mount baffle-board, by doing this, the echo reflected by thebarrier will be reflected out. And “False Echo Storage” will be applied.11If there are agitators in vessels, instrument must be mounted as far away from agitators as possible. Once installation completed, a"false echo learning" should be carried out while agitators inmotion to eliminate negativeinfluence caused by false echo of agitators. You are advised to opt for installation with standpipe if foam or wave is generated due to the action of agitators.Agitator Pulse Radar Level Instrument
Installation with StandpipeYou are advised to opt for installation with standpipe (or bypass tube) to avoid the influence on measurement caused by barriers inside vessels or foam generation.It is advised to install antenna inside of the standpipe to avoid the error caused by foam. The minimum inner diameter of standpipe should be 50mm. Avoid large cracks or welding seam when connecting standpipe. False echo storage must be carried out as well in this case.ventilation holeANote: You must NOT mount instrument inside standpipe while measuring adhesive medium.Side through Standpipe installation with Standpipe12By using standpipe, the influence of foams can be reduced.
13Power supply and current signal are carried by the same two-wire connection cable. See the Technical Specifications of this guide for detailed requirement on powersupply. A safety barrier should be placed between power supply and instrument for intrinsically safe version.See the Technical Specifications of this guide for detailed requirement on power supply.Earth-connected current output can be used for standard version of level instruments, while the explosion proof version must be operated with a floating current output. Bothinstruments and earth terminals should be connected with ground firmly and securely. Normally you can either choose to connect with the earth terminal on vessel or adjacentground in case of plastic vessels.Standard 2-wire cable with outside diameter of 5...9mm, which assures the seal effect of cable entry, can be used as feeder cable. You are recommended to use screened The two ends of shielded cable must be connected with earth terminal. The shieldedcable must be connected with inner earth terminal directly inside the transducer, while the outside earth terminal on housing must be connected with ground. In the event of earth-connected current, the shielding side of shielded cable must be connected to ground potential via a ceramic capacitor (e.g. : 1μF 1500V) in order to dampen the lowfrequency grounding current and avoid the disturbance caused by high frequency signals 5 Electrical ConnectionPower SupplyGeneral Introduction20mA/HART(2-Wire)Cable ConnectionShielding & Grounding2-wireWiring Diagram2-wire wiring used for HART1）Power Supply and Signal Output + -1 Pulse Radar Level Instrument
