Flange-mounted magnetostrictive level gauges provide continuous liquid level measurement in storage tanks, process vessels, and industrial reservoirs. Their flange connection simplifies installation and ensures a secure seal under demanding pressure and temperature. A typical model code, such as MLG-F-1000-SS316-DN80, identifies the product family, measuring range, probe material, flange size, output signal, and explosion-proof option. Confirm each code item with the supplier before ordering.

Key specifications often include a measuring range of 300 mm to 6000 mm, accuracy of ±1 mm or ±0.05% FS, resolution of 0.1 mm, and repeatability of ±0.5 mm. Output options are 4–20 mA with HART, RS485 Modbus, or Profibus; supply voltage is commonly 24 VDC. Process connections follow DIN, ANSI, or JIS standards, such as DN50, DN80, DN100, 2 in, 3 in, or 4 in. Wetted parts are usually 304/316L stainless steel, with PTFE or PFA coating for corrosive media.

Operating conditions depend on the probe and electronics. Media temperature typically ranges from -40°C to 120°C, with high-temperature versions reaching 200°C. Pressure ratings may range from 1.0 MPa to 4.0 MPa. Protection class is normally IP65 or IP67, and explosion-proof models may meet Ex d IIC T6 or Ex ia IIC T6 for hazardous areas.

When selecting a model, define tank height, liquid density, medium compatibility, flange standard, insertion length, output protocol, and environmental protection. Correct model and specification ensure stable signal transmission, low maintenance, and accurate level control in chemical, water treatment, oil and gas, and food processing applications.
