Smart Measurement in Digital Transformation: Product Value Overview

In traditional industrial level measurement, long-distance wiring is costly and prone to aging failure in corrosive, flammable, and explosive environments. The Nexisense wireless magnetic flap level gauge is designed to solve these engineering challenges.

The device combines the classic buoyancy balance principle with advanced IoT wireless technology. Through a high-precision magnetic float and non-contact magnetoresistive sensing, it converts liquid level height into accurate electrical signals. Nexisense gives traditional instruments “wireless” and “intelligent” capabilities, allowing users to remotely monitor inventory status of petroleum, chemicals, food, or wastewater systems in real time from control centers or mobile devices.

Core Technical Advantages: Designed for Harsh Industrial Environments

1. Magnetoresistive Technology Replacing Traditional Reed Switches
Nexisense R&D team eliminates issues such as sticking or magnetic failure in reed switches. Magnetoresistive technology detects magnetic field variations to determine position, offering faster response, no mechanical fatigue, and stable ±2.5%FS accuracy even under fluctuating conditions.

2. Multi-dimensional Wireless Communication Architecture
LoRa: supports private networking via Modbus-RTU gateway, cost-effective and highly penetrating.
NB-IoT/Cat.1: based on operator networks, plug-and-play, ideal for remote reservoirs, dams, and fuel stations.

3. Materials and Environmental Resistance
Wetted parts are made of 304 stainless steel (optional 316L), resistant to corrosive media. The device supports up to 2.5MPa pressure and operates from -40°C to 120°C, suitable for asphalt and high-viscosity media.

4. Intelligent Algorithm: From Level to Volume
By entering a 6-digit password (000237), users can access advanced settings, input tank cross-sectional area, and automatically calculate volume using V = S × h, displayed in cubic meters (m³).
