Intelligent spiral vortex flowmeter

The intelligent spiral vortex flowmeter adopts microprocessor technology, which has the advantages of strong functionality, wide flow range, simple operation and maintenance, and easy installation and use. Its main technical indicators have reached the level of similar foreign products. Widely used in various gas metering industries such as petroleum, chemical, power, metallurgy, and coal.

The main features of intelligent spiral vortex flowmeter are:

1. Built in pressure, temperature, and flow sensors with high safety performance, compact structure, and beautiful appearance.

2. Display temperature, pressure, instantaneous flow rate, and cumulative flow rate on site.

3. By adopting a new type of signal processing amplifier and * filtering technology, the interference signals generated by pressure fluctuations and pipeline vibrations are effectively eliminated, greatly improving the anti-interference function of the flowmeter and ensuring excellent stability for small flow rates.

4. The function of time display and real-time data storage ensures that internal data will not be lost and can be saved in any situation.

5. The whole machine has extremely low power consumption and can operate for a long time with internal battery power supply, making it an ideal on-site display instrument without the need for external power supply.

6. The anti-theft function is reliable, with password protection to prevent parameter changes.

7. The header can rotate 180 degrees freely, making installation convenient.

Installation precautions

Sensors can be installed in vertical, horizontal, or any inclined position according to the flow direction indicator;

When the pipeline is long or close to the vibration source, supports should be installed upstream and downstream of the flowmeter to eliminate the impact of pipeline vibration;

The installation location of the sensor should have sufficient space for the inspection and maintenance of the flowmeter, and should meet the environmental requirements of the flowmeter;

Avoid interference from strong external magnetic fields;

When installed and used outdoors, there should be a cover to avoid direct sunlight and rainwater erosion, which may affect the service life of the instrument;

When conducting pipeline pressure testing, attention should be paid to the pressure measurement range of the pressure sensor equipped on the intelligent flowmeter to avoid damaging the pressure sensor due to overpressure.

Attention should be paid to the influence of installation stress. The upstream and downstream pipelines of the flowmeter should be coaxial, otherwise shear stress will be generated. The installation location of the flowmeter should consider the thickness of the sealing gasket or install an elastic expansion joint on the downstream side.

Before installing the flow meter, the welding slag and other debris in the pipeline should be removed first.

When put into operation, the upstream and downstream valves of the flowmeter should be slowly opened to avoid sudden rapid airflow and damage to the starter.
