Magnetostrictive Level Transmitter Product Matrix
A magnetostrictive level transmitter (or gauge) is an industrial instrument that utilizes the magnetostrictive effect to measure liquid levels with high precision.
Its core components include an electronics housing, a waveguide, and a float containing a built-in permanent magnet.
During operation, the electronics unit transmits a current pulse along the waveguide; this pulse interacts with the float’s magnetic field to generate a torsional stress wave. By precisely measuring the time interval between the pulse transmission and its return, the system calculates the float’s position, thereby determining the liquid level.
This instrument offers advantages such as high measurement accuracy and resolution, excellent reliability, non-contact measurement, and low maintenance requirements, while also being capable of simultaneously measuring liquid levels and interfaces (such as the oil-water interface).

Industry Applications of Magnetostrictive Level Transmitters
High-precision (±1mm), continuous liquid level and dual-float interface measurement engineered for demanding industrial environments and safety-critical process control.
Oil & Gas Upstream, Refining & Petrochemicals
In crude oil extraction platforms, refineries, and tank farms, Magnetostrictive Level Transmitters deliver high-accuracy (±1mm) measurement where custody transfer, inventory management, and process safety are critical.
By deploying dual-float configurations, a single transmitter simultaneously measures total oil level and oil-water interface in separators, flash drums, and settling tanks. Flexible cable options allow seamless measurement in deep vertical oil tanks up to 25 meters.
Chemical Processing & Corrosive Media
Chemical processing units frequently handle highly reactive and hazardous media such as concentrated sulfuric acid (H₂SO₄), hydrochloric acid (HCl), caustic soda, and volatile solvents.
Magnetostrictive transmitters engineered with full PTFE/PFA linings, Hastelloy C-276, or Titanium probes isolate internal electronics completely from corrosive fumes. The non-contact wave-guide technology eliminates drift, providing maintenance-free continuous output.
Power Generation & High-Pressure Steam Drums
Thermal power plants, combined-cycle power units, and utility boilers require robust level control across high-pressure steam boilers, feed-water heaters, deaerators, and turbine lube oil reservoirs.
Equipped with high-temperature piezo-ceramic sensors and high Curie-point magnetic alloys, magnetostrictive transmitters operate continuously at temperatures up to 420°C and pressures exceeding 16 MPa, unaffected by dense steam phase dielectric fluctuations.
LPG, LNG & Cryogenic Gas Terminals
Pressurized, liquefied gases such as LPG, LNG, liquid ammonia, and underground fuel storage demand hermetically sealed sensors that can handle rapid thermal expansion and sub-zero temperatures.
Equipped with low-density floats customized down to 0.45 g/cm³ and thermal vacuum jackets, magnetostrictive transmitters deliver reliable, high-precision inventory tracking for spherical tanks and ATG (Automatic Tank Gauge) petrol station networks.
Water & Wastewater Treatment
In municipal water plants, industrial effluent systems, and seawater reverse osmosis (SWRO) desalination facilities, magnetostrictive transmitters measure chemical dosing tanks, sludge pits, and neutralizers.
Offering superior stability over ultrasonic or radar meters when surface turbulence, heavy foam, or vapor steam is present, they provide absolute level tracking without requiring periodic field recalibration.
Pharmaceuticals & Food Processing
Hygienic manufacturing environments require strict adherence to sanitary standards for purified water (PW), water for injection (WFI), fermentation vessels, and food syrup storage tanks.
Sanitary magnetostrictive transmitters feature electro-polished 316L probes (Ra < 0.4μm), dead-leg-free internal construction, and Tri-Clamp sanitary connections, fully supporting Clean-In-Place (CIP) and Sterilization-In-Place (SIP) routines.
Metallurgy & Heavy Industrial Automation
Steel mills, aluminum smelting plants, and heavy machinery workshops rely on magnetostrictive sensors not only for liquid level tracking in hydraulic power stations and lube oil reservoirs, but also for linear position feedback.
Built with extreme vibration resistance and heavy-duty armor, these transmitters endure mechanical shocks, high ambient heat, and electromagnetic interference (EMI) typical of heavy metallurgical operations.
Skid-Mounted Equipment & OEM Integration
OEM manufacturers of chemical dosing skids, oil-gas separator packages, boiler feed skids, and magnetic level gauge (MLG) bypass chambers require compact, highly reliable transmitters with non-intrusive mounting capability.
Magnetostrictive transmitters can be strapped directly onto the outside of bypass magnetic gauges. This provides zero-contact, 100% leak-proof continuous 4-20mA HART remote signal transmission without creating additional process nozzles.
