Product Value Overview

In today’s era of rising energy costs, Nexisense Intelligent Precession Vortex Flow Meter provides a high-performance benchmark solution for industrial gas metering. As a new generation of intelligent gas flow instruments, it not only overcomes the shortcomings of traditional flow meters in low-flow conditions, such as difficult metering and easy wear, but also converts working-condition volume flow into standard-condition volume flow and total volume in real time through a built-in high-precision sensor array.

Nexisense is committed to providing transparent and traceable metering data for energy-intensive industries such as petroleum, chemical, power, and metallurgy. By solving fluctuation interference on industrial sites through digital means, Nexisense ensures that the value of every cubic meter of gas can be accurately recorded, helping users make scientific decisions in complex pipeline network dispatching.

Core Technical Advantages

1. Excellent Hardware Material and Protection Rating
      Nexisense always insists on using corrosion-resistant, high-strength industrial-grade materials.
      • High-quality valve body material: Provides multiple material options including 304 stainless steel, 316L stainless steel, and aluminum alloy, which can be customized according to the corrosiveness of the medium.
      • Industrial-grade protection and explosion-proof: The whole machine has IP65 waterproof and dustproof capability and has obtained ExdbIICT6 high-level explosion-proof certification, ensuring stable operation in flammable and explosive chemical hazardous areas.

2. Advanced Algorithm Optimization and Compensation System
      Compared with ordinary flow meters, Nexisense has carried out in-depth optimization at the algorithm level.
      • Full-automatic factor correction: Built-in high-precision digital temperature and pressure sensors can automatically detect the medium environment and perform real-time dynamic correction of the compressibility factor.
      • Wide turndown ratio performance: Turndown ratio can reach 1:10 to 1:15 (customized according to specifications), effectively covering full-scenario metering from peak flow to low flow without missing or mis-metering.

3. Micro-power Design and High Reliability
      • Dual power supply mode: Built-in 3.6V/10AH large-capacity lithium battery can run continuously for several years without external power supply; it also supports external 24VDC power supply to meet the needs of real-time signal remote transmission.
      • Data security guarantee: The instrument has a large-capacity memory with data tamper-proof function, automatically recording key parameter modification logs and historical statistical data to ensure the judicial fairness of metering data.

Wiring Instructions and Installation Guidelines

• Power Wiring: When using 24VDC external power supply, please pay attention to polarity connection. If only internal battery power is used, please ensure the meter head display is activated.

• Communication Integration: RS485 communication is recommended to use shielded twisted pair. When transmitting over long distances (more than 500 meters), please install a 120 ohm termination resistor at the end.

• Installation Direction: The instrument must be installed according to the arrow direction marked on the housing to ensure the correct medium flow direction.

• Straight Pipe Section Requirements: To ensure measurement accuracy, it is recommended to maintain a straight pipe section of no less than 5DN upstream and no less than 3DN downstream.

Common Questions and Answers (FAQ)

Q1: Does the Nexisense Precession Vortex Flow Meter require regular calibration?

Although the product has no mechanical wear and has excellent long-term stability, in order to comply with legal metrology requirements, it is recommended to perform periodic verification every 1-2 years according to industry regulations.

Q2: Why does my flow meter show a small flow jump even when there is no gas flow at night?

This is usually caused by pipeline vibration or pressure fluctuations. Nexisense internally supports the “low flow cutoff” function to effectively shield working condition background noise interference.

Q3: Does the instrument support absolute pressure (Absolute Pressure) compensation?

Yes. The built-in sensor can be set to absolute pressure or gauge pressure acquisition mode according to user needs and automatically participates in the temperature and pressure compensation algorithm.

Q4: Will data be lost if the battery runs out?

No. Nexisense adopts non-volatile memory. Even in power-off state, accumulated flow and configuration parameters can be permanently saved.

Q5: Can it be used in environments containing corrosive gases?

Yes. It is recommended to select 316L stainless steel valve body according to the medium composition for better corrosion resistance.

Q6: Does the Modbus communication protocol support modification of instrument parameters?

Yes. Through the Modbus-RTU instruction set, the remote monitoring center can read the accumulated quantity and modify debugging parameters such as cutoff value under authorized permission.

Q7: Can the brightness of the instrument display be adjusted?

To maintain extremely low operating power consumption, Nexisense uses a micro-power LCD screen. It is clearly visible under strong light, but it is not recommended to run the battery-powered version in high-brightness backlight mode for a long time.

Q8: What should I do if the on-site pipeline pressure exceeds 4.0 MPa?

Nexisense provides high-pressure customization solutions. We can design and test customized models with pressure resistance up to 10.0 MPa or higher according to your working conditions.

Q9: Why choose the precession vortex principle instead of the traditional turbine principle?

The precession vortex flow meter has no rotating bearings, so it has higher tolerance to fine impurities in the medium, lower failure rate, and is particularly suitable for non-absolutely pure gases such as natural gas.
