| Magnetic flapper level indicator instrument can be used for the medium liquid level detection of various kinds of towers,tanks,slots,ball type container and boilers and other equipment.This series of liquid-level gauges can be highly sealed, anti-leakage and suitable for high temperature, high pressure, corrosion-resistant occasions.It makes up the glass plate (tube) level gauge indicating poor clarity,easy to break and other defects,and the whole process measurement without blind spot, clear display, large measuring range. The parts materials of the magnetic flapper level indicator use 1Cr18Ni9Ti、316L、0Cr18Ni9Ti、1Cr18Ni9Ti lining PTFE, PVC, PP and other materials and imported components, which have excellent reliability and corrosion resistance. |
