Jiwei Level Switch: Customized Liquid and Bulk Level Solutions for Every Industry
In industrial environments, liquid and bulk level measurement is never as simple as “buying a standard product and it works everywhere.” The complexity of the field often exceeds expectations: medium densities range from ultra-light powders at 0.02 kg/L to high-density slurries at 2.0 kg/L; viscosities vary from water-like fluids to heavily adhesive pastes; tank structures range from standard carbon steel to jacketed, pressurized vessels, with mixers, filters, or cyclone dust collectors. Additionally, rapid temperature changes, pressure fluctuations, material flow dynamics, sedimentation, vacuum suction, condensation, foam layers, flange limitations, and restricted installation spaces can make a standard level switch unstable or even completely fail.
Experienced engineers know that 70% of a level switch’s reliability comes from understanding the application conditions, not just product specifications.
For this reason, Shenzhen Jiwei Automations Ltd. follows an industry-customized strategy, rather than mass-producing standard products. Jiwei engineers have accumulated extensive real-world application data across industries, understanding why certain materials are difficult to measure, why the same device performs differently in two plants, and why laboratory tests often differ from field results. Based on this, Jiwei provides tailored probe designs, signal processing, anti-interference strategies, and installation solutions, ensuring liquid and bulk level measurements are truly aligned with real-world conditions.
This depth of customization solves common pain points, including dust causing false triggers on vibrating probes, condensation affecting radar echoes, buildup jamming float switches, and oscillation causing level fluctuations. It also avoids the risks of standard level switches, such as drifting, false triggering, blind spots, signal loss, or total device failure, making measurements reliable even under complex conditions.
1. Why Industry Customization Matters More Than Standard Products
Most field issues are not due to insufficient product specifications but due to highly variable conditions:
- Light powders easily float, and standard fork switches cannot trigger reliably
- High-viscosity materials adhere to walls, standard radar fails to echo
- High-temperature/high-pressure conditions require special seals or extended antennas
- Low dielectric media are difficult to measure
- Mobile vessels like ships or tankers face vibration interference
- Food and pharmaceutical industries require sanitary standards and CIP compliance
- Strongly corrosive chemicals generate steam or volatile compounds
Even within the same industry, different plants or tanks may require different probe structures, installation methods, and signal configurations. Jiwei’s level switches are structurally and functionally customized for each application.
2. Jiwei’s Industry Customization Approach: From Application, Not Product
a) Customized Probe Structures
- Powder: anti-clog probes, enhanced amplitude frequency vibrating rods
- Sediment-laden water: probes designed for high concentrations of suspended solids or sediment, unaffected by flow rate or sedimentation, providing reliable and continuous measurements.
- Viscous liquids: extended, anti-sticking vibrating rod switches, designed for high-viscosity fluids, unlike standard dual-purpose models. Reliable even in adhesion, stirring, or temperature fluctuation conditions.
- Granular materials: impact-resistant, vibration-proof structures
- Corrosive media: 316L, Hastelloy, coated isolation materials
- High-temperature: operates at 280°C (most competitors max 150°C) and even up to 400°C, providing leading high-temperature corrosion resistance while ensuring long-term measurement stability in aggressive media
b) Customized Signal Processing
- Steam and condensation compensation
- Dust or foam interference correction
- Mobile vessel interference suppression (ships, tankers)
c) Customized Installation & Accessories
- Limited tank top space: short antenna or side-mount options
- High-temperature tanks: extended horn tubes + insulation
- Hazardous media: Ex ia intrinsic safety, NAMUR outputs
d) Customized Testing & Validation
- Material sample testing
- Simulated tank trials
- On-site parameter optimization
Ensures the product works reliably immediately upon installation.
3. Industry Cases: Reliable Results Through Customization
✔ Chemical Industry (Steam, Corrosive, Volatile)
Special anti-corrosion radar level meters for sulfuric acid, methanol, high-salt waste liquids, with fully sealed antennas, corrosion-resistant materials (PTFE, PFA, Hastelloy), and condensation compensation. Continuous, stable echo measurement prevents overflow, leakage, and safety risks.
Jiwei also offers the first China-made level instrument Bluetooth applet, Jiwei Smart Control®, enabling parameter configuration, online commissioning, quick diagnostics, and data review via mobile devices, ideal for tight, high-temperature, or hazardous locations.
✔ Heavy Industry (Gear Oil, Lubricants)
Delivered 60 vibrating rod switches customized for high-viscosity gear oil. Using high-reliability piezo-ceramic probes rated up to 400°C with extended anti-sticking design, stable triggering is ensured even under stirring, high-temperature fluctuation, and viscous media. This represents a leading solution for continuous lubrication monitoring.
✔ Low-Density Materials
Customized solutions for ultra-low density media: vibrating rod switches measure down to 0.02 g/cm³, and fork switches down to 0.008 g/cm³. Anti-sticking designs and optimized structure effectively prevent false triggering, performance comparable to imported products.
✔ Beverage & Food Processing
Sanitary connections with mirror-polished probe surfaces (Ra ≤ 0.5 μm) reduce residue and microbial adhesion, fully meeting CIP/SIP cleaning and sterile production requirements.
✔ Transport & Maritime
Radar level meters designed for tankers and bulk carriers feature anti-sway structures and filtering technology, effectively suppressing vibration, vessel sway, and liquid surface fluctuations, ensuring long-term, reliable measurement at sea or during transit.
