1 Guided Radar with 2-wire system TGF2200 Micro Pulse Level Meter OUTLINE The TGF2200 series is a unique 2-wire continuous level-measuring instrument using TDR technology. The simple and compact design suitable for tank-top installation with no moving parts has a high cost performance with the maintenance-free and low cost installation by the simple 2-wire loop powered system. Thanks to the coaxial, single and twin s this continuous level meter is applicable to wide services including liquids, slurries, powders and granules. The keypad operation on the front display allows easy parameter setting including zero point adjustment and measuring range. The micro pulse level meter is suitable for tank and silo inventory for liquids and powders as well as level controls of the intermediate or underground tanks. FEATURES 2-wire loop powered system with less cable and low installation cost Wide applications by TDR method Elimination of false signals by DPR (Dynamic Parasite Rejection) From 50 C to 300 C and from vacuum to 4.0 MPa No influence from changes in temperature, pressure or density The can be used in segment to make it easy to use Measuring Max. 40 m in liquids, powders and granules Horizontal or vertical housing position to make the display easy to read Remote converter allows a free selection of installation Easy checking and changing of parameters without opening the cover Quick coupling system permits removal of the housing and full rotation No moving parts and maintenance free MEASURING PRINCIPLE The Guided Radar level meter TGF2200 is a continuous level meter which has been developed from a proven technology called Time Domain Reflectometry (TDR). The device transmits intermittently low-intensity electromagnetic pulse called micro-pulses along a conductor called. These pulses travel along the at a very high speed. When the pulses reach the interface of gas and liquids, or gas and powders, the pulses are reflected on the interface and travel back along the to the level device. The device measures the time from when the pulse is transmitted to when it is received. The traveling speed of the pulses is constant. The half of this time is equivalent to the direct distance from level meter to the surface of the products. The direct distance determined by above calculation is converted into a level value from the predetermined reference point. In some applications the direct distance is converted into the volume or mass using the tank table. These values are output as current signals in the form of output requirements. The traveling speed of the pulses is almost constant which is little affected by changes in pressure and temperature in the tank and is not affected by changes in temperature of the measuring object, its dielectric constant or density. 1 Transmitted pulse 2 Reflected pulse 3 Signal wave pattern 4 Measuring range 5 Air : Er 1 6 Measured objects: Dielectric constant Er > 1.6 for direct mode Er > 1.1 for TBF mode

14 PRECAUTIONS FOR INSTALLING AND USING TGF2200 Observe followings when installing and using TGF2200. Install the level meter in the ambient temperature -40 to +80 C around housing. Provide a weather protection or the likes to avoid the direct sunshine and rain splash if the level meter is exposed to them. Do not install the level meter in the place where a strong vibration is expected. Decide the installation location and height considering the dead zone (non-measurable zone) of the TGF2200. The dead zone varies with the to be used and operating conditions. See the section MEASUREMENT LIMITS. When installing two or more TGF2200s on the same tank, place them at least apart 1 m. ln order to prevent the cable from slackening when using the cable, set the counter weight afloat above tank base. 0r fix the counter weight with a tension in the cable. Consider the shape and location of the nozzle so that the does not touch the nozzle or tank wall. Avoid the ingress of foreign materials and coagulation of liquids inside the coaxial. Fasten the end of the to prevent it from vibration for the services where sloshing of liquid is expected in the tank. Install the apart from agitator or fix the at its end to avoid entanglement. You can fasten the at the end of it, if required so, but not at other positions except coaxial. Fixing the at the intermediate position using a supporting lug or other structure is allowed. However, the upper end of supporting structure to fix the becomes the end of under which non-measurable zone starts. When fixing coaxial, do not add an excessive force on it to avoid bending. Design the nozzle or installation location to keep a distance to avoid touching the with fluid from product inlet nozzle. Touching the with fluid causes a malfunction of the level meter. When the location of level meter cannot be changed, take a necessary measure such as changing direction of inflow from product inlet nozzle. Install the level meter in order to avoid touching the with fluid. Touching the with fluid by incorrect installation causes incorrect measurement. Take a necessary measure by changing direction of inflow from product inlet nozzle, when the touches with fluid. 14 TOKYO KEISO CO., LTD. TG-L1016-0E

15 Install the level meter preferably directly on the roof of the tank without a nozzle. Avoid adherence of sticky liquids inside installation nozzle. When measuring sticky liquids, avoid the accumulation of the remnants inside installation nozzle. Installing the level meter directly on the flange without a nozzle on the roof of the tank is recommended for flange connection type. Installing the level meter directly on the thread (socket) on the roof of the tank is recommended for thread connection type. When installing the level meter on the nozzle, do not make it too longer nor protrude it into the inside of tank. When installing TGF2200 on the nozzle, make the nozzle length shorter than 150 mm. The diameter of nozzle must be larger than or at least same as the height of nozzle: Nozzle diameter (d) nozzle height (h). lf this condition is not satisfied, the minimum required length of the dead zone starts from the bottom end of the nozzle. It makes the dead zone longer or may cause a malfunction. Do not protrude the end of nozzle into the inside of tank. Install TGF2200 preferably on the threaded connection (socket) Typical installation on threaded connection (socket) Do not protrude the end of threaded connection (socket) into the inside of tank. TG-L1016-0E TOKYO KEISO CO., LTD. 15

16 Installing twin cable or twin rod When installing twin cable, the diameter of nozzle must be larger than or at least 50 mm: Nozzle diameter (d) 50 mm. Make the nozzle length (h) shorter as much as possible. Installing coaxial The nozzle diameter and length has no effect on the measuring performance. Installing s on concrete roof When installing s on the concrete roof, the diameter of hole (d) must be larger than thickness of concrete (t) (+ installation nozzle). The surface of hole must be smooth. When the thickness of concrete (t) is larger than the diameter of hole (d), make the hole larger and install the on the pedestal made of metal, not installing it on the concrete. The diameter of hole (d) must be larger than thickness of concrete (t). The diameter (d) thickness of concrete (t). When the thickness of concrete (t) is larger than the diameter of hole (d), make the hole larger. 16 TOKYO KEISO CO., LTD. TG-L1016-0E

17 Installing s on a non-metallic tank Observe followings when installing single rod or single cable with thread connection. Insert a metallic sheet between the level meter and its connection seat on the tank. The diameter of metallic sheet is 200 mm or larger. Make sure that the connection thread on the level meter is screwed into the end of thread through the sheet. Use a flange of 200 mm or larger in diameter instead of connection thread if the metallic sheet is not available. If you have a device with twin rod, twin cable or coaxial, you can ignore these instructions. Non-metallic tank or sump tank Metal sheet with 200 mm or larger in diameter Precautions for installing s for measuring liquids Do not install TGF2200 near internal obstacles. Keep a distance from the to any obstacles. When installing the in a standpipe or stilling well, do not make the contact with inside the pipe. Keep a distance from the to any obstacles to prevent micro-pulses near from being influenced by them. The range in which the micro-pulses are influenced varies with the type of. See table below. Provide a standpipe or stilling well either internally or externally to measure the level inside the pipe to avoid obstacles in the vessel. Keep the straight inside the standpipe. Do not make the contact with inside wall of the pipe. Do not make it slack. The contact or slack causes a failure in measurement. Shorten the in such cases. The necessary space between the s and obstacles varies with type of s. See table below. Type of Necessary space around Coaxial 0.0m Twin rod, Twin cable Min. 0.1 m Single rod, Single cable Min. 0.3 m TG-L1016-0E TOKYO KEISO CO., LTD. 17

18 Measuring liquids inside pipes Using a stilling well (internal chamber) and bypass chamber (external chamber) is recommended. Use a standpipe if the level meter is installed near the tank wall, internal obstacles, agitators or product inlet. Using a standpipe by installing the in stilling well (internal chamber) or bypass chamber (external chamber) reduces the influences from sloshing, foams or bubbles of liquids. Stilling well (internal chamber) Bypass chamber (external chamber) Vent hole Max. liquid level Requirements for the stilling well or bypass chamber The internal and external pipes must be metallic or electrically-conductive. If the pipe is not made of metal, provide a pipe with enough size to secure necessary space for the. The pipe must be straight. The inside surface must be smooth with its roughness less than 0.1 mm. The accuracy of inside diameter must be less than ± 1 mm The Internal stilling well must have a vent hole at the higher point than the Max. liquid level. The Internal stilling well must have enough gaps between the counter weight and the inside of the pipe to make the liquids go through easily. Install the pipes vertically. Precautions for using the stilling well or bypass chamber Place the in the center of the internal stilling well. The span of the bypass chamber must cover the Max. and Min. liquid levels: One nozzle must be higher than the Max. level and another lower than the Min. level. The liquids and gases must move smoothly inside the pipes. The corrosion or adherence by fluids inside pipe is not allowed. Do not let any foreign objects into the pipe. The lower zone than bottom of internal stilling well cannot be measured. 18 TOKYO KEISO CO., LTD. TG-L1016-0E

19 Precautions for measuring powders Install the used for the powders while the tank or silo is empty. Install the level meter without any slack of cable. Use the with the end of unfixed when measuring powders. Design the shape of nozzle, threaded connection (socket) and their location so that the does not touch inside surface of tank, nozzle or socket. Install the apart more than 300 mm from the tank or silo wall. Install the so that its counter weight is located more than 300 mm above the bottom of tank or silo. Do not adhere anything on the threaded connection (nozzle) or inside of nozzle when the product is adherent. Install the as far as possible from the internal obstacles to prevent the from being entangled with them even when the moves back and forth. Use single cable for the measurement of powders. Use the with the end of unfixed. Make it free to move. Do not install the near a product inlet. Avoid the from touching with inflow of products. Start-up The start-up indication will appear in 5 seconds after power-on. The indication appears in 30 seconds later. Further 10 seconds later the correct measurement starts. The necessary time to get the correct measurement depends on the measuring conditions. The current output becomes approximately 2.8 ma just after power-on. About 10 seconds later 3.6 ma is given and 30 seconds later, the correct output is given. The necessary time to get the correct output depends on the measuring conditions.
