Overview

The real-time temperature pressure flow monitoring integrated machine is a temperature pressure flow integrated monitoring device specially developed for low flow rate conditions (1m/s~5m/s). The instrument adopts high-precision micro differential pressure/static pressure sensors and pitot tube structure design, combined with automatic calibration and automatic blowback technology, which can be widely used for real-time continuous measurement of various flue gas temperatures, pressures, flow rates, and flow rates.

Product Details

Real time temperature pressure flow monitoring integrated machine：A high-precision instrument that integrates temperature, pressure, and flow rate measurement functions, mainly used for industrial process monitoring and environmental emission control.

1、 Core principles and structure

1. Measurement principle

Flow rate: Based on the pitot tube method, the flow rate is obtained by measuring the difference between total pressure and static pressure (dynamic pressure) through an S-shaped pitot tube, combined with the smoke density (calculated from temperature and pressure).

Temperature: Direct contact measurement using PT100 platinum resistance or thermocouple, with an accuracy of ± 1%.

Pressure: Micro differential pressure sensors measure dynamic pressure, while absolute pressure sensors measure static pressure, with a typical range of ± 5kPa to ± 10kPa.

Flow calculation: Multiply flow velocity by pipeline cross-sectional area, supporting real-time temperature and pressure compensation to improve accuracy.

2. Key components

S-type Pitot Tube: Made of 316L stainless steel, corrosion-resistant and wear-resistant, suitable for high dust and high temperature (0-500 ℃) environments.

Backblowing unit: Dual solenoid valves control high-pressure gas source (≥ 0.35MPa), regularly blowing and sweeping the pitot tube to prevent particle blockage.

Intelligent processor: integrates automatic zero calibration, fault diagnosis (such as blockage prompt, voltage abnormality), and data storage functions, supporting 4-20mA analog signals or RS48

2、 Technical features and advantages

1. High precision and stability

Flow rate error is ≤± 5%, temperature error is ≤± 1%, pressure error is ≤± 1% FS, meeting the strict requirements of CEMS system for calculating total pollutant emissions.

Real time temperature and pressure compensation algorithm and dynamic calibration technology to reduce the impact of environmental fluctuations on measurement.

2. Automation and Intelligence

Support manual/automatic blowback (interval time can be set), manual/automatic zero calibration, reducing manual maintenance costs.

The LCD display screen intuitively displays data, fault codes, and operation guides, supporting local debugging and remote monitoring.

3. Reliability design

Explosion proof type (such as IIC T6) is suitable for hazardous areas such as petrochemicals, with a protection level of IP65 or above.

Fully sealed structure and corrosion-resistant materials, capable of long-term stable operation in an environment of -20~40 ℃.
