A magnetostrictive level gauge measures liquid level accurately in tanks and process systems. Its price is not fixed because each unit is configured for the application. Standard models cost USD 300 to USD 1,200. Explosion-proof, long-probe, high-temperature, or sanitary versions can cost USD 1,500 to USD 5,000 or more.

Probe length is a major price factor. A short 300 mm probe costs less than a 3,000 mm probe. Accuracy also matters: a 0.5 mm unit is cheaper than a 0.1 mm model. Output options such as 4-20 mA, HART, RS485 Modbus, and Profibus add cost. Corrosive, high-pressure, or high-temperature media may require 316L stainless steel, Hastelloy, PTFE, or titanium.

Brand, warranty, and after-sales support affect the quote. A low-cost supplier may save money now, but calibration and spare parts can cost more later. Installation type and float design also influence price. Top-mounted, side-mounted, and bypass chamber designs use different fittings.

To get a fair price, prepare specifications: range, medium, temperature, pressure, output, accuracy, connection size, wetted parts, and certifications. Ask for a quotation including the sensor, float, flange, transmitter, documents, and shipping. Compare at least three suppliers and review calibration reports. Basic water or oil models cost USD 300 to USD 700. Standard industrial models with HART or Modbus cost USD 700 to USD 1,200. Custom high-end models cost USD 1,500 to USD 5,000+. Price depends on specifications and quantity.
