TGR Wire Guided Radar Gauge. MICRO-PULSE level meter GENERAL FEATURES OPERATION PRINCIPLE

Transcription

1 -Wire Guided Radar Gauge TGR MICRO-PUS level meter GNRA TGR series is the -wire system Guided Radar Gauge which can continuously measure the level using micro-pulse. The micropulse emitted from the electronics is propagated along rod or cable probe. So the efficiency of micro-pulse propagation is high and dense. By the micro-pulse in low energy, sufficient reflection can be obtained from the products in a low dielectric constant, and it is possible to make measurement of level and interface of fluids in low dielectric constant, of organic solvents and oils, and solids. The local indication is large and easy to see at the site as graphic display is adopted. FATURS Total cost can be reduced by the -wire system level meter. TDR system is available for various applications. Measurement in high accuracy is realized in spite of -wire loop powered system. asy operation with wide graphic display Improvement in the dynamic range by modifying the specification of emitter. Measuring objects are level, interface, liquids and solids. Available for temperature and pressure in wide range. Measurement in high accuracy can be made without being influenced by the change in temperature, pressure and density. OPRATION PRINCIP TGR is a unique instrument based on TDR (Time Domain Reflectometry) technology, by which the level can be continuously measured. The electric wave called a micro-pulse is intermittently emitted, and the emitted micro-pulse reflects on the surface. The level is detected by the turnaround time of reflection until it comes back to a emitting point. The micro-pulse emitted from the electronics propagates to the surface of the measuring fluids at the fixed speed along with the rod or cable called a probe and reflects at the surface of liquids or solids where the dielectric constant changes. The level is measured by this turnaround time. The velocity at which the micro-pulse spreads is mostly fixed by about, km/sec. and is not influenced by the change in temperature or pressure. ven when these measuring conditions are changed, there is no necessity for the compensation to be made. The error over the measured level is very small, and the measurement can be made without being influenced by the change in temperature, density, dielectric constant of the fluids to be measured, and dust, vapor, bubbles etc Gas (Air) iquid t t t t t4 V V evel = Time / mitted pulse evel signal TG-M4- Aug. 5

When longer than mm, pay attention not to make it larger than the diameter of the nozzle. If this condition is not fulfilled, the dead band length is generated from the lower end of a nozzle. When the fluctuation of the liquid in a tank is intense, the stabilizing processing shall be carried out to a probe point. In the tank with a stirrer, keep a probe apart enough, or fix the top in order that a probe may not be entangled in a stirrer wing. When carrying out the stabilizing processing, the measurement can not be performed at the lower part than the upper position of the processing. When the measurement is performed inside a pipe, a probe shall be equipped in the center of the pipe. The ambient temperature in the housing should be between -4 C to +8 C. Install a blind at the place where the direct sunlight hits. When the two guide radars are installed in the same tank, detach m or more to install. When the measurement of the adhesive fluid is made, the installation shall be made so that the adhesion may not be generated inside the nozzle. In case of the measurement of powder, a single cable probe shall be used, and do not fix it, making it free. In order to prevent a cable from slackening when using a cable probe, set a weight afloat above the tank base, or fix the weight, applying the tension. Consider the shape and location of a nozzle so that the probe may not touch the nozzle and tank wall. Separate a single probe by more than mm and a twin probe by more than mm from the wall of a tank, to install the guide radar. 4 TOKYO KISO CO., TD. TG-M4-

5 -Wire Guided Radar Gauge TGR Avoid using long and narrow nozzle. Regarding the diameter of nozzle, make it larger than the nozzle length, and do not make the projection of nozzle in a tank. When the installation of nozzle is made in a concrete tub, make the sum of the thickness of concrete and the length of nozzle not to be longer than the diameter of hole. The installation is to be made in the location where the object to tank does not touch probe directly. Moreover, the main stream of flow should be separated from the probe by mm or more. When the obstructions such as a ladder, a heating coil etc. are in a tank, the installation of single rod and single cable probe is to be made, separated by mm or more from the obstruction, and twin rod and twin cable probe are to be installed, separated by mm or more.
