Magnetic Float Level Transmitter — Product Series Taxonomy(customized)

Driven by a mechanical float that moves with the fluid level and an internal reed switch/resistor chain, the magnetic float level transmitter excels at continuous liquid level and immiscible liquid-liquid interface measurements—making it a highly reliable, magnetically coupled contact-type instrument for harsh process environments.

Comprehensive Industrial Applications

Robust magnetic float level transmitters engineered for diverse processing industries, harsh environments, and sanitary standards.

Petroleum & Refining
Chemicals & Chlor-Alkali
Power Generation
LPG, LNG & Cryogenics
Water & Desalination
Pharma & Food Processing
Mining & Hydrometallurgy
Pulp, Paper & Textiles

Petroleum Refining & Oil-Water Separation

In petroleum refineries and offshore platforms, magnetic float level transmitters monitor crude distillation column bottoms, flash drums, and storage tanks.

With dual-density calibrated floats, these sensors excel at measuring liquid-liquid interface boundaries—such as oil-water separation layers in electrostatic desalters and primary production separators.

Chemical Processing & Chlor-Alkali

Handling aggressive media such as hydrochloric acid (HCl), sulfuric acid (H₂SO₄), and wet chlorine gas requires extreme material performance.

Engineered with corrosion-proof PTFE/PFA linings, Hastelloy C-276, or Titanium, magnetic float transmitters prevent chemical degradation and deliver long-term reliability in acid reactors and chlor-alkali neutralization tanks.

Power Generation & High-Pressure Boilers

Thermal and combined-cycle power facilities rely on magnetic float transmitters across boiler drums, feedwater heaters, deaerators, and steam condensers.

Rated for pressures up to PN160 / PN320 and elevated temperatures, magnetic coupling operates smoothly without being affected by high-density saturated steam or thermal expansion.

LPG, LNG & Cryogenic Fuel Storage

Pressurized and cryogenic gas applications—such as Liquefied Petroleum Gas (LPG), LNG, and anhydrous ammonia—demand hermetic containment and strict flameproof safety.

Equipped with intrinsically safe (Exia II CT6) and explosion-proof (Exd II CT6) terminal enclosures, all electrical reed elements are completely isolated from pressurized hydrocarbon vapors.

Water Treatment & Seawater Desalination

In municipal wastewater plants, industrial zero liquid discharge (ZLD) systems, and seawater reverse osmosis (SWRO) facilities, transmitters face high chloride concentrations.

Corrosion-resistant metal alloys (such as Titanium or 316L SS) protect against seawater pitting and bio-fouling in high-pressure concentration towers, raw water intake pits, and chemical dosing tanks.

Pharmaceuticals & Food Processing

Hygiene and contamination control are critical in pharmaceutical synthesis, fermentation vessels, beverage blending, and edible oil refining.

Designed with polished 316L SS or PTFE wetted parts and Tri-Clamp sanitary process connections, these magnetic float transmitters support CIP/SIP (Clean-In-Place / Steam-In-Place) procedures without dead legs.

Mining & Hydrometallurgy (HPAL)

Metal extraction processes—such as high-pressure acid leaching (HPAL) for battery-grade nickel and cobalt—involve hot, highly abrasive, and acidic mineral slurries.

Heavy-duty magnetic float transmitters manufactured with Titanium or Hastelloy wetted components withstand extreme acid corrosion and harsh mechanical slurry environments.

Pulp, Paper & Textile Dyeing

Pulp bleaching towers, liquor recovery boilers, and textile dyeing vats utilize strong bleaches, caustic solutions, and organic dyes under elevated temperatures.

Magnetic float transmitters penetrate through dense surface foam and floating fibers, ensuring continuous, drift-free liquid level tracking where optical sensors get blinded.

Buying from Instrava gives you the best of both worlds—the direct-from-source pricing of a factory, combined with the professional service, product range, and risk mitigation of an elite sourcing partner. Here is how we deliver value to your business:

Unbiased Market Curation (More Choices & Better Prices): Unlike single factories that only praise their own capacity, or traditional trading companies restricted by personal connection networks, we evaluate the entire Chinese manufacturing landscape. We benchmark and source from multiple verified factories to secure the most competitive pricing and the exact product specifications you need.

100% Transparency (Your “Brain” in China): We never hide behind the veil of being a “fake manufacturer.” We act as your transparent, in-country purchasing department. You always know exactly who is producing your goods, how much they cost, and what the real lead times are.

Uncompromised Quality & Risk Mitigation: Our business is built on long-term partnerships, not one-off high-profit transactions. We perform strict, independent quality control from your perspective before shipment, protecting you from post-purchase defects and communication breakdowns.

Streamlined Communication & Service: No more dealing with slow, production-centric factory service. We provide a single, highly responsive point of contact that manages the entire supply chain—from negotiation and quality checks to shipping logistics—saving you time and reducing headaches.

Level gauge, flowmeter, transmitter, level switch, Gas Alarm Controllers etc.

Our customer-centric philosophy prioritizes their procurement needs.

1. Initially confirm the manufacturer based on product pricing and the strength and qualifications of the production factory.

2. Verify the manufacturer’s production environment through video and on-site inspections to check the compliance of the entire product manufacturing process.

3. Ensure post-production product testing and retain data and video evidence from the verification process(testing and verification methods vary depending on the product).

Firstly, we confirm the packaged products with the factory (different products require different packaging and shipping methods. Heavy equipment and bulk shipments are securely secured within sea freight containers using custom-designed engineering steel frames, heavy-duty multi-layer wooden crates, and industrial-grade vacuum rust-proof bags. Precision instruments are protected against impacts and maintained in a stable position; the factory has extensive experience in this area. Custom labels are affixed to the outer packaging).

Secondly, we maintain communication with the freight company to confirm the condition of the goods and advise them to handle the loading and unloading processes with care.

1. Instrava offers a comprehensive 12 to 24-month warranty (specific warranty period depends on the product line), covering all manufacturing and component defects.

2. When online technical support is needed, customers can connect with factory engineers online. Real-time guidance is provided for installation, on-site calibration (for instruments), and commissioning. When on-site engineer support is needed, we will arrange for an engineer to visit the site.

3. In the event of component issues, we will ship replacement parts via international express delivery (DHL/FedEx) to minimize your project downtime.

4. Whether a product requires replacement or repair will be clearly stated in the purchase contract.
