For measuring a variety not easy to side-mounted liquid level of the reservoir, in particular underground storage tank level measurement inside. Widely used in petroleum, chemical, metallurgy, electric power, light industry and pharmaceutical industries and sectors. Top-mounted magnetic level gauge installed directly on top of the container, through the float with the liquid (or interface) to move up and down movement of the upper and lower magnetic rod driven by a magnet inside the magnetic rod driven by magnetic coupling principle of magnetic turn Board Indicators, with red and blue (red liquid gas blue) clear visual indication of the level or interface level process container, can be long-distance transmission and automatic control. UHZ series top-mounted magnetic level gauge consists of a body portion, local indicators, several parts remote transmitter and upper and lower limit alarms. Top-mounted magnetic level gauge main technical parameters Measuring range: 0-4000mm Nominal pressure: 1.0MPa; 1.6MPa; 2.5MPa; 4.0MPa Nominal diameter: DN150 Working temperature: -40 ~ 80 ℃ Accuracy: ± 10mm Medium Density: Level: ρ≥0.5g / cm3 interface level: ρ1-ρ2≥0.25g / cm3 wetted material: 1Cr18Ni9Ti Flange Standard: JB82-59 (level gauge flange: flat or convex flange) with Thermal jacket fitting: ZG1 / 2 "(female)
