Product Description Function and measurement systemmeasuring principleThe MGS series of guided wave radar level meters are "top-down" measuring instruments based on the Time of Flight (Time of Flight) principle. High-frequency pulse signals are emitted to the probe and propagate along it. When they encounter the material surface, they reflect. The reflected signal returns along the probe and is received by the instrument. Through unique equivalent sampling technology, the time difference between the emission and reception of the pulse is converted into the distance from the instrument reference point (the connection point of the instrument's process) to the material surface, thus calculating the level. This measurement method is known as TDR Time Domain Reflectometry (Time Domain Reflectometry).importThe echo pulse signal is transmitted from the probe to the electronic unit of the instrument. The microprocessor analyzes the received signal to distinguish the true level echo signal. The correct identification of the echo signal is completed by intelligent software. The measurement distance D is proportional to the travel time t of the pulse: D=c * t / 2--, where c is the speed of light. Based on the known empty tank height E, the level L can be calculated as L =E-D--. See the reference point for the empty tank height E in the figure on the right.outputAccording to the field conditions, the height of empty tank (zero point), the height of full tank (full scale) and application parameters are set to make the instrument automatically adapt to the current measurement application. According to the user's range setting, the corresponding output 4~20mA is set. Communication can be carried out through HART protocol.Overview of the instrumentApplication industry-Petroleum industry (oil field, petrochemical, oil production plant, refinery, chemical plant, coking plant, etc.)Measuring media:crude oil, light oil, natural gas, methanol, ethanol, ammonia water, benzene, polystyreneEthylene, ester, water vapor, liquid carbon dioxide, liquid nitrogen. -Power industry (high and low heating, condenser, etc.)Measurement media:raw coal bin, pulverized coal bin, fly ash binchemical water. -Metallurgical industry (steel plant, etc.)Measuring media-limestone, coking coal powder, cold return ore, raw material bin, powder bin, fly ash bin, chemical water. -Cement industry (cement plant, etc.)product advantageMeasuring media-clinker storage, powder storage, raw coal storage, chemical waterMeasurement is not affected by the following factors--Liquid density, the degree of looseness of solid material--Temperature--dust--steamThe foam on the surface of the liquid has no effect on the measurement.

Whether dealing with liquids, slurries, or other media in storage or process containers, this radar excels. Ideal for water liquid storage tanks, acid and alkali storage, and slurry storage tanks, its performance is determined by the horn aperture.1) For Class A medium, a waveguide length of 20m is recommended for optimal measurement.· MPS3700 Series Pulse Radar: Tailored for solid level measurements in expansive process containers. Its adaptability is based on the antenna opening size, making it perfect for diverse applications such as measuring coke levels, slurry storage, and solid particles.Measuring Conditions? Measurement Range: Begins where the beam contacts the tank's bottom. In tanks with disc-bottoms or conical discharge ports, levels beneath this point remain unmeasured.? For Media with Low Dielectric Constant (Class A & B): When the medium is low (as indicated in figure C), the tank's bottom becomes visible, potentially decreasing measurement accuracy. Setting the measurement zero at position C, away from the tank's bottom, is recommended.? Theoretical Measurement Range: Extends to the instrument antenna's end. Factors such as corrosion and adhesion necessitate maintaining a minimum distance A from the antenna top. Special caution is advised if condensation is present.Minimum Measurement Range B: Dictated by the chosen antenna type (refer to the table for specifics).Tank Specifications: The diameter must exceed D, and the tank's height should be at least H, as detailed in the accompanying table.

This effect is steam-type specific and more pronounced in low temperatures. An increase in the distance between measurement zero (flange) and the material surface amplifies the measurement error, as detailed in the subsequent table.gaseous phasetemperaturepressureoCoF1kgf/cm2 (14.5psi)10kgf/cm2 (145psi)50kgf/cm2 (725psi)100kgf/cm2 (1450psi)160kgf/cm2 (2320psi)nitrogen20680.00%0.22%1.2%2.4%3.89%200392-0.01%0.13%0.74%1.5%2.42%400752-0.02%0.08%0.52%1.1%1.70%hydrogen2068-0.01%0.10%0.61%1.2%2.00%200392-0.02%0.05%0.37%0.76%1.23%400752-0.02%0.03%0.25%0.53%0.86%water(Saturated water vapor)1002120.20% 180356 2.1% 263505.4 8.6% 310590 22% 364687.2 41.8%Note!
