Product Overview

In the wave of Industry 4.0, flow meters are no longer just independent measuring instruments, but crucial sensing nodes in the Industrial Internet of Things. Nexisense intelligent electromagnetic flow meter combines Faraday's law of electromagnetic induction with modern advanced digital signal processing technology. Through deep optimization of sensor structure and excitation algorithm, Nexisense effectively solves common pain points in industrial sites such as electromagnetic interference, pressure fluctuations, and medium corrosion. Whether dealing with viscous papermaking slurry or highly corrosive chemical liquids, Nexisense always provides global system integrators and engineering contractors with stable, reliable, and easy-to-integrate flow monitoring experience.

Core Technical Advantages

1. Excellent Sensor Hardware Construction
Nexisense adopts thickened flange plate integrated forming process. Compared with the common thin welded flanges on the market, our product greatly reduces signal interference caused by pipeline vibration at the physical level and effectively improves the pressure resistance upper limit. The sensor adopts symmetrical electrode layout inside, with optional materials such as 316L, titanium, tantalum, Hastelloy alloy, etc., to specifically solve electrochemical interference and corrosion problems of different media.

2. Intelligent Algorithm and Digital Meter Head
Built-in 0.8-inch high-definition wide-view LCD display screen, supporting one-key switching of multiple flow units such as cubic meter (m³), liter (L), and ton (t). The intelligent meter head has anti-reflection backlight function, ensuring data remains clearly visible under strong sunlight or dark environments. Its internal algorithm has been optimized through tens of thousands of working condition simulations, with a turndown ratio of 10:1 (up to 150:1 customizable), and still maintains extremely high sensitivity at low flow rates (≥1m/s).

3. Comprehensive Protection Rating
Nexisense provides two configurations: **integrated type (IP65)** and **split type (IP68)**. The split type model can realize long-term submersion of the sensor underwater through special sealing technology. Combined with multi-layer anti-corrosion coating, it effectively blocks the erosion of H₂O, impurities, and rust elements, ensuring ultra-long service life of the equipment in humid environments such as underground pipe networks and mines.

4. Powerful Industrial Communication and Integration
To meet the demand for real-time monitoring in modern production lines, Nexisense comes standard with 4-20mA current output, pulse output, and RS485 Modbus serial communication interface. This design greatly simplifies wiring difficulty and integration workload. On-site engineers can easily read instantaneous flow, cumulative flow, and alarm status through the master station, significantly improving system maintainability.

Technical Specifications

Application Scenarios

Environmental sewage treatment: Real-time monitoring of domestic sewage and industrial wastewater discharge flow. High protection rating is fearless of acid and alkali corrosion and impurity deposition.

Chemical agent control: In fine chemical production, flow metering of various expensive agents to ensure precise formula ratios and improve product yield.

Building heating and energy consumption management: By monitoring hot water circulation flow and combining with temperature sensors to achieve heat calculation, helping commercial real estate and parks achieve energy saving and emission reduction.

Flow quantitative control: Integrated into automated filling or loading systems, linked with solenoid valves through pulse output to achieve high-precision quantitative addition and sub-packaging tasks.

Wiring and Installation Guide

To ensure the best measurement performance of Nexisense flow meter, please strictly follow the following principles during installation:

• Pipe section requirements: At least 10×D (D is the inner diameter of the flow meter) straight pipe section in front of the sensor and 5×D straight pipe section behind to ensure stable flow field.

• Installation position: Should be installed at the lower part of horizontal pipes or vertically upward. It is strictly prohibited to install at the highest point of the pipe or vertically downward (to prevent air bubbles or partial pipe filling).

• Pump position: The sensor must not be installed at the inlet of the pump; it must be installed at the outlet of the pump to prevent negative pressure from damaging the lining.

• Communication wiring: RS485 communication is recommended to use shielded twisted pair. When multiple instruments are connected in parallel, please ensure daisy-chain connection and match 120 ohm resistor at the end.

• Exhaust suggestion: If the pipeline drop exceeds 5 meters, install an exhaust valve downstream of the sensor.

Frequently Asked Questions (FAQ)

Q1: Can Nexisense flow meter measure pure water or distilled water?
A: No. Electromagnetic flow meters require the medium conductivity ≥50μs/cm. For non-conductive media such as pure water, distilled water or alcohol, please consult Nexisense sales personnel to choose ultrasonic flow meter or other technical routes.

Q2: How to choose lining material according to working conditions?
A: Neoprene (CR) is generally recommended for sewage; polytetrafluoroethylene (F4/F46) is recommended for strong acid and strong alkali media; polyurethane (UR) lining is more advantageous for abrasive media (such as slurry).

Q3: After installation, the reading keeps fluctuating. What could be the reason?
A: Please check the following three points: 1. Is the pipe full? Partial filling will cause reading fluctuation. 2. Is the grounding good? Electromagnetic flow meters are very sensitive to equipotential. 3. Are there large frequency converters or high-frequency interference equipment nearby?

Q4: Why are 10D front and 5D rear straight pipe sections required?
A: This is to eliminate vortex interference caused by elbows, valves and other pipe fittings, ensuring that the fluid is uniform and stable when flowing through the sensor, thereby guaranteeing measurement accuracy.

Q5: Does Nexisense support battery power supply?
A: Yes. We provide models with built-in 3.6V lithium battery power supply, suitable for remote sites where external power supply is unavailable. Battery life can reach 3-5 years.

Q6: Can RS485 Modbus protocol modify meter parameters?
A: Yes. Through the standard Modbus protocol, not only can flow data be read, but also damping time, small signal cutoff value, and range can be modified remotely.
