Flange-mounted magnetostrictive level gauges are designed for reliable continuous measurement in grain and oil storage tanks. The MGL-F series uses a stainless steel probe and a flange process connection to suit top-mounted installation, avoiding side-wall openings and reducing leakage risk. Typical models include MGL-F100 for clean oils, MGL-F200 for grain silos and MGL-F300 for high-humidity or outdoor tanks. Key specifications: measuring range 0–6000 mm; accuracy ±0.5 mm; resolution 0.1 mm; probe diameter 10 mm or 12 mm; process flange DN50, DN80, ANSI 2 in or custom; wetted material 304/316L stainless steel; output 4–20 mA, HART, RS485 Modbus or relay; supply 24 VDC; working temperature -40°C to +85°C; pressure up to 1.6 MPa; protection IP65/IP67; optional explosion-proof Ex ia IIC T6 and LCD display. For grain tanks, select a probe length that covers the full material height and keep a dead zone at the top and bottom. For oil tanks, confirm fluid compatibility, sealing material and flange rating. Installation should be vertical, with the flange centered and the probe protected from inlet flow. Regular zero and span checks help maintain accuracy. Model selection should match tank height, medium, output protocol, hazardous area classification and site flange standard. With proper specification, the gauge provides stable level data for inventory, automation and safety control in grain and oil storage systems.
