Product Description

Function and Measurement System
Measuring Principle
The MGS series of guided wave radar level meters excel in delivering precision with their 'top-down' measurement methodology, rooted in the esteemed Time of Flight principle. High-frequency pulse signals are meticulously sent to the probe, journeying along its path until they meet the material surface. Upon impact, they reflect and retrace their steps back to the instrument, which, thanks to advanced equivalent sampling technology, accurately interprets the time delay between sending and receiving these pulses. This time difference ingeniously translates into the exact distance from the instrument's reference point to the material surface, thereby determining level measurements. This sophisticated approach is renowned as TDR Time Domain Reflectometry.

Import
The journey of the echo pulse signal is a marvel of technological advancement, traveling from the probe to the instrument's electronic unit. Here, the microprocessor engages in meticulous analysis to accurately identify the true level echo signal, a task accomplished through intelligent software. The relationship between measurement distance D and pulse travel time t is elegantly expressed as D=c * t / 2, where c stands for the speed of light. Given the known empty tank height E, the level L is precisely calculated as L = E - D, with the reference point for empty tank height E depicted in the accompanying figure.


Output
Tailored to adapt seamlessly to field conditions, the instrument adjusts itself based on the empty tank height (zero point), full tank height (full scale), and application parameters. This ensures an automatic alignment with the current measurement application. Users can enjoy precision control as the output is configured to 4~20mA according to specified range settings. Seamless communication is facilitated through the HART protocol.

explain	· Usually, cable probes are used to measure solid particles, and rod probes are only suitable for measuring light solid particles with good fluidity in small ranges (about 4m); · Rod or coaxial rod probes are usually used to measure small range of liquids. Cable probes are used to measure liquids with a range greater than 4m or in situations where rigid probes cannot be installed on the top space; · The coaxial rod probe can measure the viscosity of liquids up to 500cst, the coaxial rod probe can measure liquefied gas, the nozzle and the internal structure of the material tank have no effect on the measurement; · When used for measuring the material level of large bins, the cable probe should be equipped with a plastic sheath to maintain the seal and prevent the cable from breaking due to side pressure; · Corrosive media should be selected for corrosion protection; · When the measured medium is a very loose material, it can be classified as a class with low dielectric constant; · The maximum range of the instrument will be reduced due to the influence of working conditions, such as: very loose surface material, adhesion caused by wet medium.

Measurement Condition Specifications: Delve into our precise measurement conditions designed to enhance reliability and accuracy across various applications and environmental challenges.
• Measurement Range Dynamics: The range initiates from the beam's contact with the tank bottom. Note: When dealing with disc-bottom or conical discharge port tanks, levels below the contact point remain undetectable, ensuring measurement precision.
• Low Dielectric Media Considerations: For media with low dielectric constants (Class A and B), if the medium is at a minimal level (figure C), the tank's bottom becomes visible, potentially reducing accuracy. It's advisable to set the measurement zero point at position C, distanced from the bottom, to maintain accuracy.
• Theoretical Measurement Range Insights: The range can extend to the instrument's antenna end, but considering potential corrosion and adhesion effects, a safe distance (A in the figure) from the range end to the top of the antenna is recommended, particularly during condensation.
Minimum Measurement Range B: This is contingent on the selected antenna type, ensuring you can optimize your setup efficiently (refer to the table below for specifics).
Tank Dimensions: For optimal performance, the tank's diameter should exceed D, and its height must be no less than H, as outlined in the table below.

· Influence of Gas Phase on Measurement Accuracy: Understand the impact of gas phase dynamics on measurement precision for refined operational outcomes.
In environments where steam hovers over the liquid, high pressure can decelerate signal transmission. This effect varies by steam type and intensifies in low temperatures. As the distance from measurement zero (flange) to material surface increases, so does measurement error, as detailed in the accompanying table.
