Product Description

Function and Measurement System
Measuring Principle
The MGS series of guided wave radar level meters are cutting-edge 'top-down' measuring instruments grounded in the precise Time of Flight principle. These meters emit advanced high-frequency pulse signals that travel seamlessly along the probe. Upon encountering the material surface, they reflect back, allowing the instrument to capture the echo. Utilizing unique equivalent sampling technology, the pulse's travel time is accurately transformed into the distance from the instrument's reference point to the material surface. This calculation reveals the level with remarkable precision, embodying the exceptional TDR Time Domain Reflectometry measurement method.

Import
The echo pulse signal is innovatively transmitted from the probe directly to the instrument's electronic unit, where a sophisticated microprocessor meticulously analyzes the received signal. This process discerns the true level echo signal, expertly executed by intelligent software. The measurement distance D is skillfully linked to the pulse travel time t: D=c * t / 2, with c as the speed of light. Utilizing the known empty tank height E, the level L is calculated as L =E-D. Refer to the diagram on the right for the empty tank height E reference point.


Output
Tailored to field conditions, this instrument allows precise setting of the empty tank height (zero point), full tank height (full scale), and application parameters, enabling automatic adaptation to current measurement scenarios. Users can set a corresponding output of 4~20mA according to the range settings, with seamless communication achieved through the HART protocol.

Measurement medium selection	Liquid dielectric constant greater than or equal to 1.6 · Thick liquid medium	· Any medium with a dielectric constant greater than or equal to 1.6	· Any medium with dielectric constant greater than or equal to 1.6 · Medium viscosity less than or equal to 500cst · It has a strong inhibitory effect on steam and foam, and the measurement is not affected				· Any medium with dielectric constant greater than or equal to 1.4 and viscosity less than or equal to 500cst · The measurement is independent of the conductivity of the medium
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.

Blind zone and measurement distance: Optimized for minimal blind zones and enhanced measurement range.

	min	max
Cable probe	1	20	0.2	0.25
Pole probe	0.5	4	0.2	0.05
Coaxial rod probe	0.5	3	0	0.05
explain: 1. The top blind area refers to the minimum distance between the highest material surface and the measurement reference point; 2. The bottom blind area refers to the distance near the bottom of the probe that cannot be measured accurately; 3. Effective measurement distance refers to the distance between the top blind zone and the bottom blind zone. Only when the material is within this distance can the reliable measurement of the material level be ensured.
