Float-type magnetostrictive level gauges are reliable for continuous level measurement in grain and oil storage tanks. A standard model includes a stainless-steel probe, magnetic float, signal converter, and display housing. The float follows the liquid surface, and the sensing element converts its position into a precise signal.

Typical models offer measuring ranges from 0.3 m to 6 m, with custom lengths for tall tanks. Accuracy is ±1 mm or ±0.05% FS, and resolution is 0.1 mm. Output options include 4–20 mA, HART, RS485/Modbus, and alarm relays. Power supply is usually 24 VDC, with 220 VAC optional. Process connections include flange, thread, and clamp. Wetted parts are 304/316L stainless steel; float material can be selected for oil, water, and food-grade grain applications. Protection is IP65/IP67, with explosion-proof versions for flammable oil environments.

Model codes often indicate probe length, connection type, output, and explosion rating. For example, a model may be specified as range 0–3 m, 24 VDC, 4–20 mA/HART, flange DN80, 316L probe, and Ex d IIC T6. Before ordering, confirm medium density, viscosity, and tank opening size. Calibration is simple and can be completed via pushbuttons or a HART communicator.

Selection depends on tank height, medium density, temperature, pressure, and installation space. For grain and oil tanks, choose anti-condensation design, reliable sealing, and easy calibration. A stilling well or guide pipe improves stability. This gauge supports accurate inventory control, overfill protection, and automated tank management.
